Call the API reliably

Rate limits, time budgets, pagination, idempotency, and HTTP codes for moving from a prototype to a reliable integration.

Slow down before the API has to stop you

Every response includes X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Window. Read them before you receive a 429.

Scope	Limit	Window
Whole API surface	60	60 seconds
Generate a text	10	10 seconds
Create a document	10	10 seconds
Create a project	10	10 seconds
Save a source to the inbox	10	60 seconds
Archive, trash, or restore	60	60 seconds
Verify a certificate without a key	30	60 seconds

Set your client timeout to at least the operation’s published x-kaneme-timeout-seconds. Responses aren’t streamed.

Number of voices

1 voice included on Free; 2 per paid seat. An extra voice costs 5 credits; a Free account needs a first purchase before adding one. A refused creation returns 402 voice_limit_reached.

Keep reading until the cursor is null

Call the same endpoint with ?cursor=… until nextCursor is null. A cursor is opaque: copy it exactly and don’t parse it.

Retry the call, not the charge

Add Idempotency-Key to write operations. If the response is lost, send the identical request with the same key within 24 hours. The API rejects a different payload under that key.

Use the status for the family and the code for the cause

Every error contains a stable machine-readable code. An abstention isn’t an HTTP error: it returns 200 with probability: null.

Status	Cause	Action
401	Missing, unknown, or revoked credential.	Create a new key in Connections.
402	Not enough credits.	Call /estimate before the operation.
404	The resource does not exist or is not yours.	Check the identifier without probing ownership.
422	The request is valid but cannot produce a result.	Read the response code for the exact reason.
429	Rate limit exceeded.	Wait for Retry-After before trying again.
503	A measurement layer is temporarily unavailable.	Retry after a short delay.
