Kapa Ai Rate Limits

The kapa.ai Query API authenticates with an X-API-KEY and meters usage primarily by questions/answers against a contracted monthly volume rather than by a published per-second request rate. kapa.ai does not document a public numeric rate-limit table; per-account request throttling and the monthly question quota are governed by the customer's plan and enforced server-side. Specific per-endpoint values are not reconciled in this artifact.

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

It captures 3 rate-limit definitions, measuring questions, requests, and concurrent.

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 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include AI, Answer Engine, RAG, Documentation, and Developer Tools.

Backoff Strategy
Clients should implement exponential backoff with jitter on 429 responses and honor Retry-After when present.
