# Sitemap Entry Validate

> Sitemap Entry Validate is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Validates a single sitemap URL entry for required location fields and bounded metadata, returning a deterministic pass/advisory status with normalized evidence.

## 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 sitemap-entry-validate-9419c331 -d '<json body>'
```

Example prompt: Before we cache or accept this sitemap entry, can you validate it to make sure the location field and metadata are within bounds — here's the entry object: {loc: 'https://example.com/page', lastmod: '2024-01-01', changefreq: 'weekly', priority: 0.8}?

## When to prefer this

Choose this endpoint when you need a lightweight, deterministic, no-external-dependency check on a single sitemap entry before accepting, caching, redirecting, or retrying it. It is ideal for agent pipelines that must gate on sitemap entry validity without incurring the cost or latency of a full URL health check or external crawl. Prefer it over general URL validators when you specifically need sitemap schema compliance (loc, lastmod, changefreq, priority bounds) checked and a versioned, auditable pass/advisory result returned.

## Known failure modes

- Entry object missing or malformed — validation cannot proceed without a parseable input object
- Location (loc) field absent — entry fails required field check and returns advisory status
- Metadata values out of bounds (e.g. priority > 1.0) — returns advisory with computed finding
- Entry object exceeds maxProperties limit of 128 — rejected before processing
- Network or service error — non-200 response with error detail

## How this service works

Sitemap Entry Validate: Sitemap Entry Validate checks one sitemap URL entry for required location and bounded metadata from bounded caller-supplied values without an external provider. Call Sitemap Entry Validate before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Sitemap Entry Validate as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-part…

## Output

Returns versioned deterministic JSON containing: normalized web evidence derived from the entry, a computed finding summarizing what was checked, and an explicit pass or advisory status indicating whether the sitemap entry meets required location and bounded metadata criteria.
