## 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 tanship-payai-browser-sitemap-extraction-dcc03ef6 -d '<json body>'
```

Example prompt: Can you fetch the full sitemap for example.com and give me a list of all the pages you find there?

## When to prefer this

Choose this endpoint when you need automated, payment-gated sitemap extraction without managing your own browser infrastructure, and especially when the target site requires JavaScript rendering or dynamic page loading. Ideal for agents operating in a pay-per-use model over Base/USDC where spinning up a persistent crawler is overkill.

## Known failure modes

- Target site blocks automated crawlers (403/robots.txt rejection)
- Site has no sitemap.xml and crawl depth is limited
- Payment transaction fails or USDC balance insufficient on Base
- Target URL is unreachable or returns 5xx errors
- Malformed input body causes schema validation error

## How this service works

Payment-gated AI and browser automation API using the x402 protocol. All /v1/* endpoints require USDC payment on Base (eip155:8453) via x402 v2 exact scheme.

## Output

Returns a structured list of URLs comprising the site's sitemap — either parsed from an existing sitemap.xml or discovered through browser-based crawling — along with metadata about the site's page hierarchy and link structure.
