Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 delx-commerce-json-email-fields-check-c1b0060b -d '<json body>'
```

Example prompt: Check whether the email fields in this JSON object are valid — the object is {"user":"alice@example.com","contact":"not-an-email","backup":"bob@test.org"} and the fields to check are ["user","contact","backup"].

## When to prefer this

Choose this endpoint when you need a lightweight, privacy-safe, pay-per-call email format validator that operates entirely in memory with no data retention, supports verifiable delivery via cryptographic evidence, and requires no API key signup. Ideal for AI agent pipelines needing trustless, auditable validation of email fields across arbitrary JSON structures at $0.001 per call.

## Known failure modes

- Exceeds 256 fields in the fields array — request rejected
- JSON object exceeds 128 properties — request rejected
- Individual field value exceeds 8192 characters — request rejected
- Fields listed do not exist in the provided object — may return those fields as invalid or skip silently
- Malformed JSON body — HTTP 400 error
- Payment not provided or insufficient USDC — HTTP 402 error

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object with a top-level 'result' containing 'passed' (boolean) and 'invalid_fields' (array of field names that failed validation), a 'status' string ('pass' or otherwise), and an 'evidence' object including a SHA-256 hash of the input, a flag confirming no data retention, and a count of external calls made (always 0).
