idealista.com

No evidence that idealista.com (Spanish/Italian/Portuguese real estate portal) appears among any A2A launch partners or adopters. The confirmed launch partners named in Google's announcement include Atlassian, Box, Cohere, Intuit, LangChain, MongoDB, PayPal, Salesforce, SAP, ServiceNow, UKG, and Workday — all enterprise software vendors, not consumer real estate portals. Idealista is not mentioned in any A2A-related context found.

No evidence that idealista.com (Spanish/Portuguese real estate portal) is an ACP launch partner or has any documented integration with the Agentic Commerce Protocol. Known early adopters and participants center on e-commerce and retail merchants; no real-estate sector participants — and idealista specifically — appear in OpenAI/Stripe ACP partner listings or announcements. The ACP standard is also a poor structural fit for idealista's core product (property listings, not transactional checkout), making adoption unlikely in the near term.

No evidence that idealista.com (a Spanish/Portuguese real estate classifieds platform) is among the AP2 launch partners or adopters. Named partners confirmed in AP2 launch materials include Airwallex, American Express, PayPal, Coinbase, Ethereum Foundation, MetaMask, Mastercard, and ManusAI — all in payments/fintech or agentic AI, not real estate. Idealista's core business (property listings, lead generation) does not align with the agentic commerce payment flows AP2 targets, and no vendor-specific evidence was found.

No evidence found of an official MCP server or MCP integration published by idealista.com itself. All MCP-related results are third-party Apify scrapers (e.g., apify.com/lukass/idealista-scraper/api/mcp) that wrap idealista data without any affiliation or authorization from idealista. Idealista's own developer surface at developers.idealista.com is a gated REST API requiring a key obtained via a contact-sales form — no MCP protocol layer has been documented or announced.

No evidence that idealista.com (Spanish/Italian real estate portal) is a participant in or has integrated the MPP protocol. Known launch partners and Tempo ecosystem members include Anthropic, DoorDash, Mastercard, Nubank, OpenAI, Ramp, Revolut, Shopify, and Standard Chartered — no travel or real estate portals, and specifically not idealista.com. This is a not_found rather than confirmed_absent because MPP is early-stage (mainnet launched March 18, 2026) and idealista has published no public statement on it.

No evidence that idealista.com has implemented or been named in connection with NLWeb. Microsoft's confirmed early-adopter cohort at launch (May 2025, Build conference) includes Tripadvisor, Shopify, O'Reilly, Condé Nast, Redfin, Eventbrite, and Priceline — idealista.com appears in none of these lists. Not confirmed_absent because no idealista-specific deprecation or opt-out statement was found; the result is simply an absence of any trace.

No usable finding available for this protocol (no legitimate scan available within the candidate window).

No evidence that idealista.com has implemented WebMCP or exposed any window.AICommands tool surface. Searches returned only coverage of the protocol itself (with Google, Microsoft, Chrome, and general web commentary as the relevant actors) and idealista's own existing REST API and property listing tools. WebMCP appears to be an early-preview protocol with no confirmed real-estate sector adopters identified.

No evidence of idealista.com appearing in any x402 launch partner list or integration announcement. Known x402 partners include Cloudflare, Google, Visa, Circle, Stripe, Amazon Web Services, Vercel, and Stellar — none related to idealista. Idealista is a Spanish/Italian/Portuguese real estate portal with no identified developer API surface oriented toward micropayment or stablecoin settlement.

Property listing search and discovery across Spain, Portugal, and Italy — covers residential, commercial, garages, rooms, and plots; supports natural-language queries returning photos, prices, and descriptions. Does not support contacting sellers, saving searches, or posting listings.

Property search and listing retrieval API (read-only) for real estate listings across Spain, Italy, and Portugal; supports querying by location, property type, operation type (sale/rent), and price filters. No listing-submission or supply-side management capability found.

Idealista operates a proprietary REST Search API (versioned, current references show v3.5) at api.idealista.com. Access requires submitting a request at developers.idealista.com/access-request and receiving approval; credentials are not self-serve. Auth uses OAuth 2.0 client credentials (API key + secret issued at approval). No evidence of a separate supply-side or listing-management API distinct from this search surface.

Direct HTTP checks for https://www.idealista.com/llms.txt, /AGENTS.md, /agents.md, /.well-known/agent, and /.well-known/ai-catalog.json all returned HTTP 000 (connection refused/blocked from the sandbox), preventing a positive confirmation. A targeted site-search for these files on idealista.com returned no results — only unrelated property listings. No third-party references or vendor announcements indicate idealista.com has published any self-declaration file. The HTTP 000 responses reflect a network block from the research environment rather than confirmed file absence, but the lack of any external evidence further supports not_found over unable_to_verify.
