limit_count: 1
note: >-
  Exactly one numeric rate limit is published across Linden Lab's whole API
  surface, and it is stated in prose on a wiki page rather than signalled at
  runtime. No Second Life endpoint returns any RateLimit-*, X-RateLimit-* or
  Retry-After header — verified against live 200 and 400 responses on
  api.secondlife.com on 2026-08-25, whose only non-standard header is
  x-ll-request-id. An agent cannot discover its remaining budget from the API; it
  has to have read the wiki.
rate_limits:
  - api: Second Life Name to Agent ID API
    endpoint: POST https://api.secondlife.com/get_agent_id
    scope: per-api-key
    limit: 2
    window: 1s
    burst: not documented
    status_on_exhaustion: 403
    error_body: >-
      JSON object with `error` and `message` fields (same envelope as the probed
      400 bad_input response).
    headers_returned: []
    method: searched
    source: https://wiki.secondlife.com/wiki/Name_to_agent_ID_API
    note: >-
      The docs state "403: Rate limiting exceeded (>2 requests/second)". Not
      probed to exhaustion — deliberately, since doing so would mean abusing a
      live production endpoint.

  - note: >-
      These are publisher-side refresh intervals, not consumer rate limits. They
      are the only guidance Linden Lab gives on polling frequency: there is no
      documented ceiling on requests to /datafeeds/*, and no cache-control or
      ETag-based conditional-request guidance either. Polling a 3-minute feed more
      often than every 3 minutes buys nothing.
