    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.

    Why it is in this group

    • The description's first verb is "read": a word for reading.
    Description, as the server wrote it
    Reads invoices, bills and receipts from PDF into structured JSON — vendor, customer, dates, PO, line items, discount, tax, shipping, total, balance due — and checks the arithmetic: quantity × unit price, lines to subtotal, tax rate, total and balance due. The response says exactly which figures don't add up. Returns vendor, customer, invoice number, dates, PO, line items, subtotal, discount, taxes, shipping, total, amount paid and balance due, plus checks (passed true/false, or null when the figures aren't printed). $0.04 per page (up to 25 pages) in USDC per successful read via x402, quoted before you pay; failed reads are free.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
