01

POST the document

Send a PDF or Excel as multipart, or a file URL. Pass the prior application to enable period-over-period checks.

02

We reconcile, async

A job extracts every figure and runs the reconciliation rules: line math, retainage, the G703→G702 handshake, over-billing.

03

Get reconciled JSON

Receive a webhook when the job completes (or poll). The payload is versioned, structured, and flagged to the cent.

API pricing

Priced per document. One pay application is one document. Effective price drops with volume.

Sandbox & test mode
Separate sk_test_ keys run the full pipeline unmetered and unbilled. Build the whole integration before you go live.
Webhooks
Reconciliation is async. Subscribe to job events, or poll the job endpoint.
US data residency
Documents and results are processed and stored in the US.
Never trained on your data
Your documents are never used to train models.
Auto-delete on a timer
Source files are removed automatically after processing. You control retention.
On the Business plan? You get a higher API allowance.
Business includes a capped API on-ramp of 250 pay-apps / month, rate-limited, so a technical buyer can prototype in production, then graduate to a dedicated API plan as volume grows.
