idempotency:
  supported: false
  notes: >-
    No Idempotency-Key or replay-safety contract is documented. Request/Response calls are reads;
    duplicate subscription attempts are managed by CorrelationID rather than an idempotency header.
request_tracing:
  mechanism: CorrelationID
  notes: >-
    Every request and subscription carries a client-assigned CorrelationID; all resulting events and
    messages (PARTIAL_RESPONSE, RESPONSE, SUBSCRIPTION_DATA, SUBSCRIPTION_STATUS) are correlated back
    to it. This is the BLPAPI equivalent of a request-id.
  schema: json-schema/blpapi-core-messages-schema.json#/$defs/CorrelationId
pagination:
  style: none
  notes: >-
    Responses are complete, delivered as one or more PARTIAL_RESPONSE events terminated by a RESPONSE
    event. HistoricalDataRequest bounds result size with maxDataPoints; intraday requests bound by
    startDateTime/endDateTime windows.
field_selection:
  style: explicit-field-lists
  notes: >-
    Requests enumerate Bloomberg field mnemonics (fields[]); overrides adjust calculation inputs.
    Field discovery via //blp/apiflds (fieldSearchRequest / fieldInfoRequest) replaces sparse-field
    conventions.

rate_limits:
  signaling: >-
    No HTTP rate-limit headers (non-HTTP transport). Limits are product-level (subscription counts,
    daily/monthly data caps per Desktop/SAPI/B-PIPE entitlements); LIMIT-category responseError
    signals when a cap is hit.
