This list is exhaustive for public API v1. Do not infer undocumented endpoints, request parameters, response fields, or compatibility guarantees. Ignore extra fields unless the API reference or OpenAPI document defines them.

## Markdown negotiation

Request raw documentation with Accept: text/markdown on https://datapublica.dk/docs, /docs/api, /docs/api/authentication, /docs/mcp, or /docs/errors. Stable .md files are linked from each page.

Canonical public company and person pages also support Accept: text/markdown. Successful responses use content-type: text/markdown; charset=utf-8, vary: Accept, and x-markdown-tokens. This page-content behavior is separate from the authenticated JSON API.

Anonymous endpoints used by the website are website support surfaces, not the official API. Do not call or infer them as stable integrations.

Machine-readable: GET /v1/resolve?q=datapublica.dk · GET /v1/domain/datapublica.dk · this page as Accept: application/json or text/markdown · MCP lookup_domain

Claim my listing on Agent Web Map for datapublica.dk:
1. POST https://agentwebmap.com/v1/sites/datapublica.dk/claims and keep claim_id and claim_secret private.
2. Publish the verification line "AgentWebMap verification: <token>" (token from step 1) in https://datapublica.dk/llms.txt, or use the DNS, meta-tag or well-known method the response describes. This only verifies the listing; your website and domain remain yours.
3. POST https://agentwebmap.com/v1/sites/datapublica.dk/verify with {"claim_id": "...", "claim_secret": "..."}.
4. Save the api_key from the answer; it manages the listing (PATCH https://agentwebmap.com/v1/sites/datapublica.dk).
MCP equivalent: tools begin_ownership_claim, then verify_domain, at https://agentwebmap.com/mcp. Docs: https://agentwebmap.com/docs#verify
