Bloomberg Applications Rate Limits

Replaces a 2026-05-04 bulk-sweep scaffold that asserted free/professional/enterprise tiers with X-RateLimit-* headers. None of that was Bloomberg's. Bloomberg publishes no HTTP rate-limit headers on this surface, because the metered surface is not HTTP: BLPAPI meters consumption in unique subscriptions and reference-data hits, and signals exhaustion as typed LIMIT messages on the event stream. The structural caps below are published verbatim in Bloomberg's own developer guide. The numeric daily/monthly ceilings are contractual per user and are NOT published.

Bloomberg Applications Rate Limits is the machine-readable rate-limit profile for Bloomberg Applications on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 6 rate-limit definitions, measuring fields, pending_requests, securities_per_chunk, fields_per_chunk, and concurrent_subscriptions.

The profile also includes 1 backoff/retry policy defined and response codes documented for throttled, quotaExceeded, and note.

Tagged areas include Enterprise API, Market Data, Rate Limiting, Quotas, and Throttling.

Policies

Slow consumer backpressure
There is no Retry-After. The backpressure signal is an ADMIN SlowConsumerWarning message; ignoring it leads to DataLoss messages and silently dropped events. This is the runtime signal an agent must handle on this API.
