OpenAPI Specification

openapi: 3.2.0
info:
  title: '{{siteName}} Public Agent API'
  version: '{{version}}'
  description: 'Anonymous, read-only API for clients and Agents. No API key is required.


    Picking an endpoint: answer a person''s question inside an AI agent -> read /api/v1/agent, which lists Markdown addresses made for agents. Show recent or today''s items -> /api/v1/items. Show what is trending right now -> /api/v1/hot-topics. Show the daily digest -> /api/v1/dailies/latest; the weekly and monthly reports -> /api/v1/weeklies/latest and /api/v1/monthlies/latest. Keep a complete local copy of the selected set -> /api/v1/selected/snapshot once, then /api/v1/selected/changes forever.


    How often to poll: use each response''s Cache-Control s-maxage as the minimum interval, and always send If-None-Match: an unchanged resource answers 304 with an empty body. On 429 or 503, honour Retry-After. There is no push channel (no SSE, webhooks or streaming): poll on an interval.


    Keep responses small: send Accept-Encoding: gzip or br (curl --compressed). To follow new items, page back only until you reach an id you already have instead of re-reading the whole 7-day window on every poll; to keep every selected item, read /api/v1/selected/snapshot once and then only /api/v1/selected/changes.


    Report dates, weeks and months identify fixed editions, but corrections and withdrawn citations can change their public content. Revalidate retained copies with If-None-Match after Cache-Control expires; do not treat a dated report as immutable.


    Titles and summaries are generated from third-party sources; the original is always linked in links.original.'
