Hand your agent the receipt, the invoice and the contract. It hands back the fields.

Documents arrive as photos, scans and PDFs. Your agent turns each one into structured fields it can file, total or act on, with one reader for every kind of document.

How your agent does it

4 calls, one connection

An agent works the finance inbox: a photo of a coffee receipt, a supplier invoice and a supply contract arrive in the same hour.

Every step goes through the same key and the same connection, with no account at any of the providers behind them.

  1. Image to Text (OCR) €0.05

    Reads the text off the photographed receipt.

    x402 image-to-text

  2. Receipt Categorisation €0.05

    Turns the receipt text into an expense: vendor, date, amount and category.

    x402 receipt-categorize

  3. Invoice and Receipt Extraction €0.50

    Pulls the supplier, totals, VAT and bank details out of the invoice PDF.

    x402 invoice-extract

  4. PDF Data Extraction €0.30

    Reads the contract and answers what it was asked: the payment terms and the notice period.

    x402 pdf-extract

  5. The result

    Every document becomes fields the agent can file: the receipt as an expense, the invoice ready to check, the contract terms on record.
