Velrim

Extract structured data from a document (PDF or image, passed as document_base64 or as the upload_key of a staged upload) against a JSON Schema you supply. Returns a typed object and, for every field, a state (present, null, or missing), a calibrated confidence score, and an anchor (the source page and bounding box). The confidence is calibrated against published reliability curves (https://velrim.com/reliability), so a 0.9 means the field is right about 90% of the time on that document class — branch on it directly: act on a field at or above your accept threshold, escalate the fields below it and any that are missing. Use each field's anchor to check it against the source page.

Poll an asynchronous extraction job by its job_id (from POST /v1/jobs on the Velrim API; velrim_extract itself is synchronous and never creates jobs). Returns the job status and, once complete, the same typed result as velrim_extract: per field a state (present, null, or missing), a calibrated confidence score, and an anchor (source page and bounding box). Confidence is calibrated against published reliability curves (https://velrim.com/reliability) — branch the same way: act on a field at or above your accept threshold, escalate the rest, and use each anchor to check a field against its source page.
