    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

Capabilities

Tools 8

check_coverage

Says whether HOUSINGFAX can produce a report for a province (name or two-digit INE code) and, optionally, finds the municipality in the official street directory. Status covered, not_yet_covered (Navarra: foral adapter pending) or unrecognized; not_yet_covered never means no risk. In the Basque Country (Araba, Bizkaia, Gipuzkoa) the report covers the whole building, not a single flat. municipalityLookup unavailable means the directory did not answer: unknown, not missing. Call it before search_address when you are not sure the place is covered.

Discovered
create_free_report

Queues the report for the building resolved with resolve_building and returns a private link (previewUrl) and a statusToken for get_report_status. Every report is free: it is the full report with PDF, with the building condition assessment when the building has an IEE/ITE record, generated in minutes. CONSENT: before calling, show the person the consent text returned by get_products (consent.text, same language) with its terms and privacy links, and set consent=true only if the person has explicitly accepted it in this conversation; pass consent.statementSha256 as consentStatementSha256. Never accept on the person's behalf. The email is optional (ready notice with the link and the PDF) and only with the person's permission. If the answer is CHANNEL_AT_CAPACITY or CLIENT_LIMIT, wait the retryAfterSeconds it gives and try again. The link is private: give it only to the person, never publish it. Always tell the person: it is a preliminary, automated report built from public records, not a technical inspection, valuation, certificate, safety assessment or legal advice; probabilities are given as words (very low to very high), never as percentages; a check without data (○) means unknown, not negative or safe; Navarra is not covered yet; the report is only available as a private link.

Discovered
get_products

Returns the HOUSINGFAX report for a home in Spain (productMode free): a single product, the full report with web view and PDF, free of charge, with the building condition assessment when the building has an IEE/ITE record. Also returns the capacity limits of the channel (no daily cap) and the consent text (with its SHA-256) that the person must accept before create_free_report. Use it when someone asks what HOUSINGFAX offers or before ordering. Always tell the person: it is a preliminary, automated report built from public records, not a technical inspection, valuation, certificate, safety assessment or legal advice; probabilities are given as words (very low to very high), never as percentages; a check without data (○) means unknown, not negative or safe; Navarra is not covered yet; the report is only available as a private link.

Discovered
get_report_status

Returns the status of a report created with create_free_report: queued, in_progress, ready, failed or expired, with the private link when ready. Wait pollAfterSeconds between calls. withLimitations=true means some source did not answer and its check shows ○ no data with the reason (unknown, not negative). Give the link only to the person.

Discovered
list_checks

Lists the 22 numbered checks of the report (title, question it answers and whether its source is integrated yet) and the meaning of the ✓ / ⚠ / ○ marks. Use it to explain what the report looks at. Checks marked pending_integration show as ○ no data, never as a negative result. Always tell the person: it is a preliminary, automated report built from public records, not a technical inspection, valuation, certificate, safety assessment or legal advice; probabilities are given as words (very low to very high), never as percentages; a check without data (○) means unknown, not negative or safe; Navarra is not covered yet; the report is only available as a private link.

Discovered
purchase_report

Not available: every report is free; use create_free_report. This tool stays in the contract for compatibility and answers NOT_FOR_SALE without creating anything.

Discovered
resolve_building

Identifies the building from an address found with search_address (object address) or from a cadastral reference (14 characters = building or plot; 18 or 20 = a single flat). Give either cadastralReference or address, not both. status resolved returns a resolutionToken (valid 15 minutes) for create_free_report, the building's public cadastral data and whether an IEE/ITE record exists (ieeAvailability; unverified means the registry did not answer, not that there is none), which decides whether the report includes the building condition assessment. status select_unit lists the units: ask the person which flat, or repeat with the 14-character reference and scope=building for the whole building. Only non-protected cadastral data is returned. Do not publish the address or reference.

Discovered
search_address

Two steps to build an address. kind=municipality with provinceCode and q returns municipalities and their codes. kind=street with provinceCode, municipalityDgcCode, municipalityIneCode (from the first step) and q returns streets with streetTypeCode and streetCode (and localityId in the Basque Country). Pass the chosen street, the house number and the codes to resolve_building. Only for places check_coverage reports as covered. Do not store or publish the address.
