  Invoca publishes no rate limits. Every page of the developer portal was read for a rate,
  quota, throttling or 429 statement and none exists: the design-principles page, the error
  handling page, the API-credential guidelines, and each API reference (Transactions, Signal,
  Call, Call Ingestion, Calls In Progress, Network Integration, Bulk Ringpool, legacy
  Ringpool) document status codes but no limit and no rate-limit response headers. The
  harvested SMS Messaging OpenAPI declares no 429 response on any of its 12 operations.
  The Invoca Support knowledge base (support.invoca.com, community.invoca.com) is
  authentication-gated (HTTP 401), so a limit published only to customers would not be
  visible here.
headers:
  documented: []
  observed: []
  note: >-
    No X-RateLimit-*, RateLimit-* or Retry-After header is documented anywhere in the public
    developer portal, and none could be observed because every Invoca API endpoint requires a
    credential.

  note: >-
    Invoca positions the Bulk Ringpool API as the high-throughput replacement for the legacy
    Ringpool API for high-request-per-second trackable-number allocation. This is a capacity
    statement, not a published limit — no numeric rate is given.

- surface: plan quotas
  note: >-
    The only published numeric ceilings are commercial, not per-request: 6,000 / 12,000 /
    18,000 annual local or toll-free numbers and 5 / 50 / 100 custom Signals across the Pro /
    Enterprise / Elite tiers. Captured in plans/invoca-plans-pricing.yml.
