description: >-
  Bloomberg publishes no rate limits for the Data License REST API or the Server API on any
  anonymously reachable page, and no rate-limit headers appear on the live anonymous responses.
  Consumption on these APIs is governed contractually — by entitlement, dataset scope and
  Data License request volume in the customer's agreement — rather than by a published
  requests-per-minute ceiling. Bloomberg does maintain a "Web API Connectivity Policy", but it is
  served from the Enterprise Console (console.blpprofessional.com/about/82), a JavaScript-rendered
  application whose content is not present in the delivered HTML.
limit_count: 0

headers:
  observed: []
  note: >-
    No RateLimit-*, X-RateLimit-* or Retry-After header was returned on any anonymous request. The
    401 and 403 responses carry only content-type and the vendor error envelope.
responseCodes:
  throttled: unknown
  note: The status code returned on exhaustion is not documented publicly.
evidence:
  - url: https://api.bloomberg.com/eap/catalogs/
    status: 401
    finding: No rate-limit headers on the response; body is the JWT-missing error envelope.
  - url: https://api.bloomberg.com/
    status: 403
    finding: No rate-limit headers on the response.
  - url: https://console.blpprofessional.com/about/82
    status: 200
    finding: >-
      "Web API Connectivity Policy" is a client-side-rendered SPA route; the served HTML is a
      2.3KB shell with no policy text.
note: >-
  This file replaces a 2026-05-04 bulk-sweep scaffold that asserted free/professional tiers at
  10 and 100 requests per minute with X-RateLimit-* headers. None of that was ever published by
  Bloomberg. An honest limit_count of 0 with the probe record is the correct measurement.
