Extend Ai Rate Limits

The Extend API enforces account- and workspace-scoped throughput controls. Synchronous processor endpoints (/parse, /extract, /classify, /split) carry a five minute per-request timeout and are intended for onboarding and testing, while production traffic is expected to use the asynchronous run endpoints, batch endpoints, and webhooks. Workflow runs accept a priority value (default 50) that influences scheduling under load. Specific numeric request- and credit-per-minute limits are not publicly enumerated and are managed per account and plan, so this artifact is not reconciled.

Extend Ai Rate Limits is the machine-readable rate-limit profile for Extend on the APIs.io network, in the API Commons Rate Limits shape.

It captures 5 rate-limit definitions, measuring seconds, requests, runs, priority, and bytes.

An exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes response codes documented for throttled.

Tagged areas include Document Processing, Document AI, Intelligent Document Processing, OCR, and Rate Limiting.
