Danny Keane Npc Chat API

  title: Danny Keane API (dannykeane.com) Npc Chat API
  version: 1.0.0
  description: 'Public HTTP endpoints on dannykeane.com, the personal site of Danny Keane. No authentication on any endpoint.


    Pagination: list endpoints (/api/v1/work) are cursor-paginated. Pass limit for the page size; each page returns next_cursor, null on the last page -- send it back as cursor for the next one. Cursors are opaque tokens.


    Async jobs: send Prefer: respond-async to POST /api/v1/batch for a 202 whose Location (and body status_url) is /api/v1/jobs/{id}; GET it for the result. Jobs are stateless -- the id carries the request, the work runs when you poll, nothing is stored -- and ids expire an hour after creation.


    Versioning: the stable surface is /api/v1/. Breaking changes ship as a new version prefix; a deprecated endpoint answers with Deprecation and Sunset headers (RFC 9745 / RFC 8594) at least six months before removal.


    Deprecation policy: every /api response carries `Link: ; rel="sunset"` (RFC 8594 section 6), pointing at this policy before any Sunset date is set. Nothing is deprecated today.


    Rate limits: every response carries advisory RateLimit-Limit, RateLimit-Remaining, RateLimit-Reset, and RateLimit-Policy headers (60 requests per 60-second window per endpoint); a 429 carries Retry-After.


    Errors: every 4xx/5xx body is the ErrorResponse object -- a machine-readable `code`, a human-readable `error`, and an optional `hint`.


    The site also runs a Model Context Protocol server at https://dannykeane.com/mcp (Streamable HTTP, JSON-RPC -- not modeled here; see the server card at /.well-known/mcp/server-card.json), a docs MCP server at https://dannykeane.com/docs/mcp for searching and reading the site''s documents, and publishes llms.txt at https://dannykeane.com/llms.txt.'
