notes: >-
  Illustrator desktop has no public REST API (scripting is local via
  ExtendScript / UXP). Rate limits apply only to the Firefly Services
  Vector / Pattern / Recolor APIs. Numeric per-second / per-minute
  ceilings are not published on the public docs and vary per endpoint.
description: >-
  Server-side rate limits for Illustrator-related APIs apply to the
  Firefly Services Vector, Pattern, and Recolor endpoints. Limits are
  governed by per-account concurrency caps and the available generative-
  credit balance; sustained excess returns 429.

  - name: Backoff Strategy
    description: Exponential backoff with jitter; honor Retry-After when present.
  - name: Generative-credit pacing
    description: >-
      Calls decrement the generative-credit balance; depleted balance
      returns a billing-state error rather than a 429.
  - name: Concurrency caps
    description: >-
      Each Firefly endpoint has a concurrent-request cap per account;
      exceeding it returns 429 with Retry-After.
