Extract

The extract endpoint is the primary entry point for the Talonic API. Send any document and receive schema-validated structured data with per-cell provenance and confidence scores.

Request

Send a multipart/form-data request with the document file and an optional schema. See authentication for header requirements and schema formats for all schema options.

Parameters

Examples

curl -X POST https://api.talonic.com/v1/extract \
  -H "Authorization: Bearer $TALONIC_API_KEY" \
  -F "file=@invoice.pdf" \
  -F 'schema={"vendor_name":"string","invoice_number":"string","total_amount":"number","due_date":"date"}'

Response

For small documents, the API returns 200 OK with the extraction result inline. For larger documents, it returns 202 Accepted with a job ID — poll via the jobs endpoint or use webhooks for async notification.

Pipeline processing

The extract endpoint triggers the four-phase pipeline. The Resolve phase classifies the document using the 529-type ontology. The Agent phase extracts values. The Validate phase applies the confidence gate. The Re-read phase cross-checks flagged values. Results include per-cell provenance linking each value to its source region.

Error handling

See the error reference for all error codes. Common errors include file_too_large (exceeds plan limits), unsupported_format, and invalid_schema.
