  Re-searched 2026-09-04 against the Biogen developer portal (https://developer.biogen.com/io-docs,
  HTTP 200), the portal's own search index (https://developer.biogen.com/search, HTTP 200 — 4 indexed
  documents, none describing limits), the non-production portal
  (https://developer1.biogen.com/io-docs, HTTP 200) and the provider's published API definition
  (https://developer1.biogen.com/swagger/export/23683, HTTP 200). NO published limit, window, burst or
  rate-limit response header was found anywhere. limit_count is 0 because Biogen publishes no numbers;
  the contractual entry below is a description of how limits are governed, not a published limit.

description: Biogen does not publish a public API rate-limit policy. Any throttling, concurrency, or
  quota controls live inside individual partner / B2B integration agreements rather than on a public
  developer portal.

notes: No public rate-limit documentation. Reconcile against the active partner agreement when one
  is in force.

limits:
  - name: Partner integration
    scope: contract

policies:
  - name: Backoff
    description: Clients receiving a 429 should respect any Retry-After header and apply exponential
      backoff with jitter.
  - name: Contractual escalation
    description: Throttling adjustments and quota raises are handled through the Biogen partner
      success contact rather than self-service.
