Idealista Listing Alert Bot
Scoped API key management and permission dashboard for AI agents in startups and tech teams.
Idea as submitted
Fencepost is a security platform providing scoped identity and access management (IAM) for AI agents deployed by startups and mid-market tech teams. Unlike the common practice of sharing identical API keys among multiple AI agents, Fencepost enforces fine-grained permissions, automatic credential rotation, and audit logging per agent. Each bot is assigned scoped access to only the APIs it requires, such as limited Gmail read access for an email-drafting bot or time-limited Stripe access for a payment workflow. This prevents security breaches and unauthorized access and enables rapid freezing of compromised agents.
Built on OAuth 2.0 principles and a credential vault leveraging PostgreSQL, Fencepost integrates initially with AI platforms like OpenAI, Anthropic, and automation tools like Zapier and Make. It offers a unified dashboard for teams to oversee agent permissions and activities. The pricing model scales per agent from $5 to $15 monthly, with compliance-focused packages starting at $500 per month to assist startups preparing for SOC 2 audits. Fencepost targets a growing $9.14B market in 2026 exploding toward $139B by 2034 as AI adoption and security needs surge.
This solution addresses acute AI security pain points for startups lacking mature IAM tools tailored for AI agents, enabling safer AI deployments and regulatory compliance while saving the cost and risk of building internal controls or risking incidents.

02 — Gate Evaluation
Gate Evaluation
✕
Buyers already paying for something similar?FAIL
CasaRadar.io charges €24.95 one-time for PRO. Botize charges €19-49/month for automation including Idealista integration. Generic monitors (Distill, Visualping, Wachete) charge €5-54/month.
✕
Purchase-intent signals visible?FAIL
CPC exists on broad property search keywords (€0.12-0.46 for Madrid/Barcelona rental terms) but is near-zero on alert-specific keywords. No ads detected in any SERP analyzed. The purchase intent is for property search broadly, not for alert tools specifically.
✕
Clear entry use-case?FAIL
Well-defined wedge: Telegram bot that sends real-time alerts for new Idealista rental listings in Madrid/Barcelona matching user's price, location, and room criteria.
✕
Clear monetization step?FAIL
Tiered subscription model (€5/10/20 per month) with market comparables: CasaRadar €24.95 one-time, Botize €19-49/month, generic monitors €5-15/month.

Understanding the Job
Before looking at competitors or keywords, we decompose the underlying job your customers are trying to get done.
03 — Task Decomposition
Task Decomposition
Primary Goal: Secure the right property (rental or purchase) in Spain's competitive market before someone else takes it
1
Monitor new listings across portals
Continuously check Idealista, Fotocasa, Habitaclia, and other portals for new properties matching criteria. Currently done by manually refreshing searches multiple times daily or relying on slow email digests.
Define search criteria (location, price range, rooms, size, features) → Check Idealista.com every few hours for new results → Check Fotocasa.es and Habitaclia.com as secondary sources → Compare new listings against remembered previous listings → Repeat across multiple neighborhood/price combinations
2
Evaluate listings quickly
Once a new listing is spotted, assess if it's worth pursuing by reviewing photos, description, location, price history, and agent details. Time pressure makes this stressful.
Open listing detail page → Review photos and floor plan → Check exact location on map → Assess price vs. market average → Look for red flags (too cheap, no photos, etc.)
3
Contact landlord/agent immediately
First responders often win in competitive markets. After finding a good listing, must contact immediately via the portal's messaging, phone, or WhatsApp.
Compose inquiry message → Attempt phone call if number available → Schedule viewing slot → Follow up if no response
4
Track price changes and listing updates
Monitor existing saved listings for price drops, status changes, or new information. Oportunista.net serves this specific niche with price history tracking.
Track which listings have reduced in price → Track which listings have been taken down (rented/sold) → Re-evaluate previously dismissed listings if price drops
5
Manage multiple searches efficiently
Active searchers often have 3-10 saved searches across different neighborhoods, price ranges, or property types. Keeping track across portals becomes a cognitive burden.
Organize saved searches by priority → Deduplicate listings across portals (Idealista + Fotocasa often have same listings) → Track which listings have been seen/dismissed/contacted
04 — Friction Points & Critical Sequence
Friction Points & Critical Sequence
Manual refresh cycle: Users must check Idealista 5-10+ times/day to catch new listings, creating a tedious monitoring loop
Forced by: Idealista's native email alerts are digest-based (daily roundup) not real-time [Source: competition-analysis.md, Idealista native alerts]. Push notifications exist in the app but speed is unclear.
Impact: Properties in Madrid/Barcelona can receive 50+ inquiries within hours of posting. A 4-8 hour delay from digest emails means missing the window entirely.
Multi-portal fragmentation: Same listings appear across Idealista, Fotocasa, Habitaclia, Pisos.com — users must check all separately
Forced by: No single aggregator covers all Spanish portals with real-time alerts. CasaRadar.io aggregates 12+ portals but is Barcelona-only [Source: competition-analysis.md].
Impact: Doubles/triples the monitoring burden. Users miss listings that appear on one portal before others.
Technical barrier for self-hosted bots: OSS solutions (idealista-notifier, Flathunter) require server setup, Python knowledge, and ongoing maintenance
Forced by: Open-source Telegram bots require self-hosting, server costs, and anti-scraping workaround knowledge [Source: competition-analysis.md, GitHub projects].
Impact: 90%+ of property seekers are non-technical and cannot use these free alternatives, leaving them with manual checking or slow email digests.
No listing deduplication: Users who check multiple portals see the same listing repeatedly without realizing it
Forced by: Each portal is a silo. No tool cross-references listings across portals for individual users.
Impact: Wasted time evaluating duplicates. Cognitive overload when managing 5-10 active searches across 2-3 portals.
No price intelligence at moment of alert: When a new listing appears, users don't know if the price is good relative to the neighborhood average
Forced by: Oportunista.net offers price history for individual listings, but not in the alert flow. There's no 'this is a good deal' signal at discovery time.
Impact: Users must manually assess value, adding evaluation time when speed matters most.

⚙
Critical Sequence
New listing appears on Idealista → User becomes aware of the listing (BOTTLENECK — speed determines outcome) → User evaluates listing quality and fit → User contacts landlord/agent → User schedules and attends viewing → User secures the property (application, deposit, contract)
Most fragile: User becomes aware of the listing — This is the step where the entire critical sequence can fail before it even starts. If awareness is delayed by hours (via digest email) or missed entirely (manual checking), the user never gets to evaluate or contact. Competitors (both native alerts and OSS bots) all attempt to fix this link, confirming it as the highest-leverage intervention point. [Source: competition-analysis.md — all direct competitors target this exact step]

Patterns
- No purpose-built paid Idealista alert SaaS exists for most of Spain. CasaRadar.io is the only discovered commercial product but is Barcelona-only with an unusual one-time payment model rather than monthly SaaS. Madrid, Valencia, and other cities are unserved.
- Native platform alerts (Idealista, Fotocasa, Habitaclia, Pisos.com) are all free but widely perceived as slow — digest emails and delayed push notifications. User complaints about speed are a documented pain point.
- Generic web monitors (Distill.io, Visualping, Wachete) are the current substitute but require technical setup, have no property-specific filters, and check as infrequently as every 10 minutes even on paid plans.
- Telegram is validated as a delivery channel by multiple open-source projects and private investment channels. WhatsApp is validated by CasaRadar.io but carries Meta Business API cost complexity.
- Open-source self-hosted bots (idealista-notifier, Flathunter) demonstrate technical feasibility and real user demand but serve only technical users willing to self-host — a minority of the ICP.
- Pricing signals: CasaRadar.io charges €24.95 one-time for 2 months (~€12.48/mo equivalent), suggesting willingness to pay in the €10-15/mo range is realistic. Generic monitors charge $5-28/mo. Proposed €5-20/mo tier is well within market norms.
Gaps
- SimilarWeb traffic data unavailable — Apify monthly usage limit exceeded. Cannot verify CasaRadar.io traffic or confirm it is a real business vs. ghost site.
- CasaRadar.io active paying user count is unknown — only 5 public reviews found. Cannot confirm revenue traction.
- Idealista native alert delivery latency is unverified empirically — official docs describe both push and digest but actual minutes-to-notification is not documented.
- No Fotocasa 'Radar Search' pricing or coverage details confirmed — unclear if it is free or paid, or whether it covers all of Spain.
- Botize polling interval for Idealista tasks is unverified — determines whether Botize can actually deliver real-time (minutes) alerts.
- No Product Hunt or AppSumo listing found for any Idealista-specific paid alert product — gap in discovery coverage.
- Spaininter.com Telegram bot pricing is entirely unknown.
- AlternativeTo.net not searched directly — may reveal additional niche competitors.

07 — Content Strategy Matrix
Content Strategy Matrix
The competitive content landscape for Idealista alert tools is almost nonexistent — direct competitors (CasaRadar.io, Oportunista.net) have near-zero organic search visibility (0 ranked keywords in Spain's top 20). This creates a wide-open content opportunity. The real SEO competition comes from real estate portals themselves (Idealista, Fotocasa, Habitaclia) which dominate high-volume property search SERPs. However, 20/27 analyzed keywords have Easy SERP difficulty with 4+ weak-authority domains in the top 10, and sites like kelify.com (PR 0) and redpiso.es (PR 2.71) rank for valuable terms. The strategic play is content-led acquisition: rank for property search intent (guides, comparisons, neighborhood analysis) and convert readers to alert subscribers. No competitor pursues this strategy — the gap is entirely uncontested.

The Idealista Listing Alert Bot addresses a genuine, validated pain point in Spain's competitive rental market. The critical sequence is clear: speed-to-awareness directly determines success in securing properties, and Idealista's native alerts are acknowledged as slow [Source: competition-analysis.md]. Forum discussions on Chollometro and Forocoches confirm active user demand for faster Telegram-based alerts.
However, three structural challenges make monetization difficult. First, search demand for the product category is effectively zero — none of the 50 alert/notification/bot seed keywords registered any search volume on Google Spain [Source: keyword-report.md, 0 vol for all 18 'Idealista Monitoring & Alerts' cluster keywords]. This means organic SEO cannot be the primary acquisition channel; growth must come from community marketing, app stores, or word-of-mouth. Second, the competitive landscape is dominated by free alternatives: Idealista's own alerts (free), multiple open-source Telegram bots (free, self-hosted), and CasaRadar.io (€24.95 one-time, not SaaS) [Source: competition-analysis.md]. Third, CPCs are extremely low (€0.05-0.46 on broad property terms, near-zero on alert terms) indicating minimal advertiser willingness to pay in this category [Source: keyword-report.md].
The strongest strategic signal is the geographic gap: CasaRadar.io only serves Barcelona, leaving Madrid (140K+ monthly searches for 'pisos alquiler madrid'), Valencia, and other cities unserved by any purpose-built paid alert tool [Source: competition-analysis.md, keyword-report.md]. The B2B pivot toward real estate agents (who have higher WTP and professional urgency) is the most promising path to viable unit economics, but requires a different feature set (multi-portal monitoring, CRM integration, lead alerts) beyond simple consumer alerts.

Automated First-Response Service
Done-for-you (Mechanic #4)
Don't just alert the user — automatically send a pre-written inquiry message to the landlord/agent on their behalf. The user wakes up to scheduled viewings, not just notifications.
Validation test
Survey 50 active property seekers: 'Would you pay €15/month if we auto-contacted landlords on your behalf within 5 minutes of a new listing?' Track interest and concerns.
Rental Application Platform
Move to Higher-Level Job (Mechanic #1)
Move beyond alerts to own the entire 'secure a rental' job: alerts → evaluation → application → document management → signing. Become the anti-Idealista for renters.
Validation test
Track drop-off in the alert-to-secured funnel: how many alert recipients actually secure a property? If <5%, the higher-level job has massive room for improvement.
Cross-Country Expansion (Italy, Portugal)
Geo expansion
Idealista operates in Spain, Italy, and Portugal. Build alert bots for all three markets simultaneously, serving expats moving between Southern European countries.
Validation test
Check Idealista.it and Idealista.pt search volumes and competitor landscape. If similar gap exists, cross-country launch could multiply TAM 2-3x.

15 — Pricing Strategy
Pricing Strategy
Free Tier (Lead Magnet)
€0/month
Free forever — 1 search, Idealista only, 30-minute delay, basic Telegram alerts
Essential to compete with the dominant free alternatives. The free tier must be better than Idealista's native alerts (Telegram > email, more responsive) but limited enough to drive upgrades. Without a free tier, acquisition cost is prohibitive given zero search demand.
Comparables
- Idealista native alerts: free, email digest [Source: competition-analysis.md]
- idealista-notifier (OSS): free, self-hosted [Source: competition-analysis.md]
Free users may never convert. Could become a money-losing infrastructure burden. Must enforce strict rate limits.
Pro Tier (Consumer)
€7.99/month or €19.99 one-time for 2 months
5 searches, multi-portal (Idealista + Fotocasa + Habitaclia), real-time alerts (<5 min), Telegram + WhatsApp, price-drop notifications
Positioned between CasaRadar's one-time payment and generic monitor subscriptions. The one-time option (€19.99/2mo) mirrors CasaRadar's model for price-sensitive users who are searching for a fixed period. Multi-portal aggregation is the key differentiator over free tier.
Comparables
- CasaRadar.io: €24.95 one-time for 2 months PRO [Source: competition-analysis.md]
- Distill.io: $12/month (generic monitoring) [Source: competition-analysis.md]
- Wachete: $5.40/month (generic monitoring) [Source: competition-analysis.md]
CasaRadar at €24.95 one-time may anchor expectations too low for monthly SaaS. Users searching for 2-3 months may prefer one-time payment over subscription.
Agent Tier (B2B)
€29.99/month
Unlimited searches, all portals, real-time alerts, API access, client matching alerts, CRM webhook integration, team sharing, priority support
Agents justify the cost with one client match per month. The tool pays for itself if it helps secure even one additional listing or client. Below Botize Scale (€49) but offers more value for this specific use case. Positioned as the SMB alternative to CASAFARI's enterprise offering.
Comparables
- Botize Automate: €19/month for general automation [Source: competition-analysis.md]
- Botize Scale: €49/month [Source: competition-analysis.md]
- CASAFARI: premium pricing (exact price unknown, enterprise-tier) [Source: web search]
Small agency market may be too niche in Spain. Agents may need CRM features beyond our scope. CASAFARI could launch a cheaper SMB tier.
16 — Prioritized Next Steps
Prioritized Next Steps
1
Time Idealista's native alert speed empirically — create a test listing and measure when push notification + email arrive. If alerts come within 5 minutes, the speed advantage is negligible and the entire premise collapses. If >30 minutes, proceed.
This is RAT #2 (risk 8, impact 10). The entire product's value depends on being meaningfully faster than Idealista's native alerts. Must resolve before building anything.
Clear data: Idealista native alert latency = X minutes. If <5min, KILL. If 5-30min, PARK and find differentiation. If >30min, PROCEED with speed as core value.
N/A — foundational assumption test2
Build minimal Telegram bot MVP (1 week) — single search URL input, Idealista scraping every 5 minutes, Telegram delivery. Deploy for personal use and recruit 20-50 beta testers from Chollometro/Forocoches.
RAT #1 (risk 9, impact 10): will anyone actually use and value this? Fastest way to test is build + share. Telegram bot development is trivial (<40 hours). Zero infrastructure cost initially.
20-50 active beta users. Track: daily active usage, listings received, user retention at day 7/14/30. Qualitative: would they pay €5/month?
bot telegram idealista (0 vol — community distribution only)3
Post in 5 Spanish property-seeking communities introducing the free bot — Chollometro, Forocoches, Reddit r/spain, Facebook 'Alquiler Madrid' groups, Telegram @pisosmadrid channels.
RAT #5 (risk 7, impact 8): can we acquire users without SEO? Community posts are the fastest, cheapest test of organic demand. If a free bot gets no traction, a paid one certainly won't.
50+ signups from community posts. Track: which community converts best, what questions/objections appear, how many request features (multi-portal, WhatsApp, price alerts).
pisos alquiler madrid (140K vol — audience overlap, not SEO)4
Interview 10 small real estate agents in Madrid about their listing monitoring workflow — do they manually check Idealista? Would they pay €30/month for instant alerts on private listings?
RAT #4 (risk 6, impact 8): B2B pivot is the most promising unit economics path. But we don't know if agents actually need this or already have better systems. 10 interviews resolve this cheaply.
Clear signal: 5+ agents say 'yes, I'd pay' → build agent tier. Fewer than 3 → abandon B2B angle.
paginas de alquiler de pisos particulares (2.5K vol)5
Publish a 'Mejores portales inmobiliarios de alquiler en España 2026' comparison guide targeting 'portales alquiler pisos' (310 vol) and 'paginas de alquiler de pisos particulares' (2.5K vol).
Content-led acquisition test. These keywords have Easy SERPs and problem-intent matching our value prop. The comparison guide naturally positions our alert bot as the recommended companion tool.
Page 1 ranking within 2-3 months. Track: organic traffic, alert bot signups from article CTA, newsletter conversion rate.
portales alquiler pisos (310 vol, Easy SERP, 5 weak spots)6
After 30 days of beta, introduce paywall: free tier (1 search, 30-min delay) + Pro at €7.99/month. Track conversion from free to paid.
Only after validating demand (steps 1-3) should you test willingness-to-pay. Premature paywalling kills a product nobody knows about yet. 30 days gives enough data on usage patterns.
Target: >5% conversion from free to paid within first month of paywall. If <2%, the consumer SaaS model is unviable — consider one-time payment or ad-supported.
