ChatHome

ChatHome (chathome.lu) is an AI-native property search and decision-intelligence platform for buyers, renters and estate agents in Luxembourg and its cross-border commuter belt in France, Belgium and Germany. It combines conventional and natural-language listing search with commune-level market data, property valuation, risk analytics, commute and financial tools (mortgage, notary fees, buy-vs-rent). For developers and AI agents it publishes public JSON endpoints, an OpenAPI description, an llms.txt index, and an authenticated MCP server and A2A endpoint. The site is operated by AnalyticoTech, a SARL incorporated in France (per the chathome.lu Legal Notice).

ChatHome publishes 5 API contracts indexed on the APIs.io network, including Protected Agent API, Agents API, Listings API, and 2 more. Tagged areas include Company, Real Estate, Property Search, Luxembourg, and Housing.

The ChatHome catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

ChatHome’s developer surface includes authentication, documentation, support, engineering blog, and 38 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented) Ask about this →
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks Ask about this →
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too Ask about this →
Agentic Commerce Well-Known Document +5 pts — a parsing /.well-known/ucp.json or acp.json declaring a version and at least one service, OR (0.27) a live x402 payment challenge from _data/x402-adoption.json — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's Ask about this →
