The OpenAPI 3.1 contract, generated from the code that serves these addresses: https://everytownland.com/api/openapi.json. Every response carries a Link header to it and to this page.

• null means the source does not say it, or did not answer; never an empty string or a zero. When a source did not answer, complete is false and the response is served with no-store.
• Every address in a body is absolute; each response names its page (page_url) and its Markdown twin (markdown_url).
• The same envelope on every success, spread last: source, served_by, terms, documentation, notice. These names are reserved.
• A collection that can outgrow a response is paginated with limit and offset: a page block with the total and the absolute addresses of the next and previous pages, the same in a Link header. An unreadable parameter falls back to the default.
• No owner is ever served: the owner of a parcel is in the Land Registry of Tailte Éireann, on landdirect.ie, for a fee. No planning applicant is ever served.
• 30 requests a minute per address on /api/ and the MCP server, counted per Cloudflare location; beyond, a 429 with retry-after and theratelimit-* headers, which only this refusal carries. The pages and their Markdown twins are not limited.

• Additive, with no version number: a field may appear; none disappears or changes meaning under a caller, and an address does not move.
• A weak ETag on every response, If-None-Match honoured, an empty 304.
• Open CORS, with etag and link exposed. No rate limit.
• x-robots-tag: noindex: read by programs, not indexed as pages.

An error carries no envelope and is served with no-store. Its type is one of the anchors below; instance is the path asked for, and received what was read.

• Every page of a county, a townland, a civil parish or a parcel has a Markdown twin at the same address followed by .md: /westmeath/golden-island.md, /westmeath/ballymahon-road-athlone.md, /parcel/2755835.md, /westmeath/parish/multyfarnham.md, /westmeath.md. Each figure names its source.
• An MCP server at https://everytownland.com/mcp (also /api/mcp): stateless, POST only, protocol revisions 2026-07-28, 2025-11-25, 2025-06-18, 2025-03-26. 7 tools, which return the text of the twins: search_irish_places, get_irish_townland, get_irish_street, get_irish_land_parcel, get_irish_parcel_at_point, get_irish_civil_parish, get_irish_county.
