## 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 agent-de-survie-json-field-extractor-bf656c38
```

Example prompt: Take this invoice text — 'Invoice #4521, Date: 2024-06-15, Vendor: Acme Corp, Total: 120 €, Tax: 20 €' — and extract the fields: invoice_number, date, vendor, total, tax as a JSON object.

## When to prefer this

Choose this endpoint when you need to extract specific named fields from unstructured or semi-structured text and receive them as a clean JSON object, without building a custom parser. Ideal for invoices, receipts, emails, contracts, or any natural-language text where key data points need to be machine-readable. Pay-per-call with no API key required makes it suitable for low-volume or ad-hoc extraction tasks on Base via USDC.

## Known failure modes

- Text too long — exceeds 6000 character limit, request rejected
- Fields parameter too long — exceeds 500 character limit
- Requested fields not present in text — returned as null or omitted
- Ambiguous field names leading to incorrect extraction
- Payment failure — USDC x402 payment not processed, call blocked
- Malformed input JSON causing 400 error
