## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability extract-invoice-data-c2ea3194 -d '<json body>'
```

Example prompt: Can you extract all the structured data from this invoice PDF — I need the vendor name, line items, amounts, dates, tax, and payment terms: https://example.com/invoice-2024-Q1.pdf

## When to prefer this

Choose this endpoint when you need to automatically parse invoice documents (PDF, DOCX, or image formats) into structured, machine-readable data for accounting, ERP, or accounts payable workflows. It is best suited for cases where you have a document URL or base64-encoded file and need vendor, line item, tax, and payment term fields extracted in one call. Prefer it over general-purpose OCR when you specifically need invoice-domain semantics and structured output.

## Known failure modes

- Document URL is inaccessible or returns a non-200 status — extraction fails with a fetch error
- File format is unsupported or corrupted — returns parsing error
- Base64 data is malformed or truncated — returns decoding error
- Invoice image is too low resolution to extract text reliably — returns partial or empty results
- Document is not an invoice (e.g. a contract or report) — returns incorrect or empty structured fields
