## 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 syntexa-agentshelf-sitemap-url-extractor-1e2de868 -d '<json body>'
```

Example prompt: Can you fetch all the URLs listed in the sitemap at https://example.com/sitemap.xml so I can see what pages are indexed there?

## When to prefer this

Use this endpoint when an agent needs to programmatically discover all URLs from a sitemap or sitemap index without risking SSRF vulnerabilities. It is ideal for seeding web crawlers, performing SEO audits, or mapping site structure. Prefer the unpaid sandbox endpoint (/v1/sandbox/sitemap-urls) for testing; use this paid endpoint when the sandbox is unavailable or production reliability is needed.

## Known failure modes

- Invalid or malformed sitemap URL returns an error
- SSRF-blocked internal/private IP addresses are rejected
- Sitemap index deeper than one level is not fully traversed (only one level returned)
- Non-XML or malformed sitemap content may result in parse errors
- URLs exceeding 2048 characters or shorter than 8 characters are rejected
- Network timeouts if target sitemap server is slow or unreachable
- Payment failure if USDC balance is insufficient

## How this service works

Call when an agent needs URLs from a sitemap or sitemap index (SSRF-safe, one index level, cap 1000). Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/sitemap-urls first.

## Output

A list of up to 1000 URLs parsed from the given sitemap or sitemap index (one level deep), returned in a structured format suitable for downstream crawling, indexing, or analysis tasks.
