​
Sync parse

Default when blob size is under server PARSE_SYNC_MAX_BYTES. Supported types depend on stored Content-Type (PDF, DOCX, CSV, XLSX). Counts toward parse_ops quotas. Per-minute parse rate limits by tier (429 PARSE_RATE_LIMIT).

​
Async parse

202 queued when async is enabled and the host has QStash configured. Optional callback_url: HTTPS with publicly resolvable host (validated server-side). Body optional for sync.

​
Poll status

Returns status, structured result when complete, or error message on failure.

​
Callback delivery audit

Lists persisted HTTP attempts for the async parse callback (newest first): attempt_number, status (success / failed), http_status, last_error, created_at. Same 404 / BLOB_NOT_FOUND rules as poll when the parse is not yours.

​
Replay callback (optional)

Re-sends the successful-parse callback (same JSON + HMAC as the worker). Requires parse complete, HTTPS callback_url, and result present. 403 CALLBACK_REPLAY_DISABLED when the host has not enabled replay; 422 if preconditions fail; 429 CALLBACK_REPLAY_RATE_LIMIT (per-minute cap).

​
Errors

Common codes: PARSE_TOO_LARGE_SYNC, PARSE_UNSUPPORTED_TYPE, PARSE_QUOTA_EXCEEDED, PARSE_RATE_LIMIT, PARSE_ASYNC_DISABLED, BLOB_NOT_FOUND, CALLBACK_REPLAY_DISABLED, CALLBACK_REPLAY_RATE_LIMIT, PARSE_NOT_COMPLETE, PARSE_CALLBACK_URL_MISSING, PARSE_RESULT_MISSING.
