POST /v1/extract

Invoices, receipts, and estimates. Structured JSON. No sales call.

Sidera Extract is a self-serve API for developers. Upload a PDF or image, get a stable schema with line items, totals, and per-field confidence. Documents are processed in memory and discarded.

Stable schemas

Invoice, receipt, and contractor estimate types share one documented shape: parties, dates, currency, line items, tax, totals, payment terms, confidence.

Bring your own schema

Pass a JSON Schema when the built-in types are not enough. Invalid model output is repaired once, then optionally sent to a fallback model.

Privacy by default

Uploaded files are never written to the database. Logs keep request metadata only: pages, type, latency, key prefix.
