response_headers:
  - name: Retry-After
    on: 429 and 503 responses; seconds to wait before retrying
  - name: Asa-Concurrency
    on: every successful response; current in-flight vs allowed (e.g. "3/20")
  - name: Asa-Rps
    on: every successful response; current average RPS vs ceiling (e.g. "8/10")
  - name: Asa-Attempts
    on: every response; number of internal upstream retries used
  - name: Asa-Cost
    on: every response; credits spent (5 standard, 0 for any non-2xx)

  - scope: per-key (Custom plan, $100-$2,000/mo)
    window: sustained, short averaging window
    limit: 50-500 rps sustained
    burst: 2x sustained for 3s
    concurrency: 100-500+ concurrent in-flight
notes: >-
  Two ceilings apply per API key: concurrency (in-flight requests) and sustained RPS. 429 responses
  carry a standard Retry-After header and the JSON error envelope with error code "rate_limited";
  429s are never billed. Batch POST submissions consume one concurrency slot only for the duration
  of the POST; batch items are processed under a separate internal worker budget. The MCP server
  README additionally states a 120 requests / 60s per-key ceiling. Official SDKs (Node/Python/Go/CLI)
  respect Retry-After automatically and ship a client-side token-bucket limiter. Short-term limit
  boosts are available by emailing info@chocodata.com.
