description: >-
  Bloomberg publishes NO rate limits for any of its data APIs, and its API responses
  carry no rate-limit signalling. Consumption is governed by contractual data
  entitlements and per-security or per-dataset licensing rather than by request-rate
  quotas an agent can read at runtime.
  SUPERSEDES a 2026-05-04 bulk-sweep scaffold that asserted 10 / 100 / 1,000
  requests-per-minute tiers and X-RateLimit-* response headers. None of that was
  harvested from Bloomberg and none of it is served by Bloomberg; it has been removed
  rather than left to be read as published limits.
limit_count: 0
limits: []
headers: {}
headers_note: >-
  No RateLimit-*, X-RateLimit-* or Retry-After header appeared on any observed
  api.bloomberg.com response. The headers actually returned are X-Request-ID,
  X-Content-Type-Options, X-Frame-Options, Content-Security-Policy and, on /eap/*,
  Access-Control-Allow-Origin / Access-Control-Allow-Methods.
responseCodes:
