Extracting data from certificates of deposit
A bank issues a certificate of deposit as a promise to repay a sum with interest on a fixed date, and a negotiable one can be sold on before then. Every issuing bank engraves its own form. Trust departments and archives digitize them in batches, arriving as scans and photographs of paper.
A holder needs the issuing bank, the principal, the rate, the term and the value at maturity. A custody or treasury system books the instrument from those, and prices it against the date it falls due.
What makes certificates of deposit hard
Handwriting over engraved print
The amount, the term and the rate are written or typed into blanks on a printed form, in a mix of scripts.
A choice left in the form
A certificate offers to pay the bearer or the order of a named holder, with a note to delete whichever does not apply.
Stamps stacked down the edge
Revenue stamps sit along one side, each carrying its own value, outside the flow of the certificate's text.
Parse, extract, verify
Parse
Parse turns the document into reading-order Markdown and a hierarchy of blocks (text, tables, figures), and grounds each block to its exact location on the page.
Extract
You define the fields in a JSON schema, and Extract returns their values in a consistent, structured format, each linked back to where it appears in the Markdown.
Verify
Each value links back to where it appears, down to the character range in the Markdown, and the page and bounding box in the source document, so every result can be verified.
One negotiable certificate of deposit, end to end
About this document: A Barclays Bank D.C.O. negotiable certificate of deposit, No. 301, issued in Johannesburg. Published by the Office of the Comptroller of the Currency on its history pages. One landscape image, black and white, 600 pixels wide, completed by hand and typewriter on an engraved form, with three revenue stamps down the edge and two signatures.
Processing objective: The objective is to read the instrument's terms off a small, old reproduction: who issued it, for how much, at what rate and for how long. The figures agree, since the principal plus 3.65 per cent for 180 days gives the R101,800 the form prints as its value at maturity.

Documents into data
Accurate
The best accuracy on the difficult documents other tools get wrong, such as messy scans, complicated tables, checkboxes and handwriting.
Auditable
Every answer cites its sources. Values come back with an audit trail (page, bounding box, character range) so a human can review them.
Agentic
Applies multi-step reasoning, and plans before it acts. Handles documents it has never seen before and adapts to variations.
API-first
Composable APIs that drop into any tech stack and can be called from anywhere. Easy to build on and embed in your pipelines and products.
Affordable
Cost-competitive rates with complete price transparency. Spend controls before you run, and every job reports its exact cost.
Enterprise-grade
Built for production and scale from day one. Fully observable and monitored, running securely in our cloud or yours.
Built for high-volume, high-throughput production
- Zero data retention
