Append Style Agent Batch Items
Append up to 20 more documents to a batch that is still processing.
Rejected with 409 once the batch is sealed (1000 documents reached, or every
document has finished) — create a new batch instead. Send an
Idempotency-Key header to make retries safe: the same key + payload
replays the original 202 instead of appending the documents again.
Authentication
Bearer authentication of the form Bearer <token>, where token is your auth token.
Path parameters
Headers
Optional client-generated key making this submission idempotent: a retry with the same key and payload returns the original accepted response instead of submitting the documents again. Reusing a key with a different payload returns 409.
Request
Optional per-batch defaults applied to any item that omits the field.
Response
Lifecycle of a style-agent batch (see design-docs/style-agent-batch-checking.md).
A batch is running while any item is non-terminal; it becomes
completed (and sealed) once every item reaches a terminal state.
