authentication:
  style: api-key
  details: >-
    api_key query parameter, or Authorization "Bearer {api_key}" header, or
    domain-restricted public keys via X-Authorization-Public-Key for client-side use.
  artifact: authentication/intrinio-authentication.yml
pagination:
  style: cursor
  request_params: [next_page, page_size]
  response_fields: [next_page]
  default_page_size: 100
  max_page_size: 10000
  details: >-
    Paged responses include a next_page field; pass it back as a next_page query
    parameter to fetch the following page. next_page is null on the last page.
    Default 100 records per request; page_size may be raised to 10,000 (subject to
    special limits).
idempotency:
  supported: false
  details: >-
    Read-only data API — requests are GETs and naturally idempotent, but Intrinio
    documents no Idempotency-Key style contract.
versioning:
  scheme: host-based
  current: v2 (API version 2.140.0 reported by the API root)
  details: >-
    The v2 Web API lives on its own host, https://api-v2.intrinio.com. The unversioned
    root returns {"name":"Intrinio API","version":"2.140.0"}.
error_envelope:
  fields: [error, message]
  artifact: errors/intrinio-problem-types.yml
rate_limiting:
  signaling: HTTP 429 (limits) and 503 (throttle/timeout); no documented rate-limit response headers
  bulk_request_limits: {free: 1 per minute, paid: 1 per second, custom: contact sales}
  throttle_limit: 100 requests per second for free-data-feed-only users
  timeout: 25 seconds per request (dropped with 503 after that)
  artifact: rate-limits/intrinio-rate-limits.yml
streaming:
  style: websocket
  details: >-
    Real-time equities and options prices are delivered over two-way WebSocket
    connections (separate hosts per feed) rather than webhooks.
