## 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-sitemap-entry-validate-51802217 -d '<json body>'
```

Example prompt: Can you validate this sitemap entry for me — it has loc set to https://example.com/page, priority 0.8, and changefreq weekly — and tell me whether it's structurally valid?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use, no-signup validation of individual sitemap entry objects with cryptographic evidence of processing (SHA-256 input hash, zero-retention guarantee). Prefer it over general XML validators when you need machine-readable structured results suitable for agent pipelines, or when operating on Base/Solana USDC payment rails via x402 without an ongoing subscription.

## Known failure modes

- Malformed entry object causes a 400-level error if required fields are missing or types are wrong
- Priority values outside 0.0–1.0 range may return valid:false rather than an error
- Non-URL values in loc field will return valid:false with appropriate evidence
- Oversized entry objects exceeding 128 properties will be rejected
- Payment failure via x402 protocol results in 402 Payment Required before processing begins

## 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 containing the validated loc URL, a boolean indicating whether the entry is valid, the priority value, an overall status string ('pass' or 'fail'), and an evidence block with an input SHA-256 hash, a flag confirming no data was retained, and a count of external calls made (always 0).
