## 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 x402-gateway-domain-competitors-finder-9d073428 -d '<json body>'
```

Example prompt: Find the top 20 organic search competitors for shopify.com in the United States — I want to see which domains are competing with them most in Google search results.

## When to prefer this

Choose this endpoint when you need fast, pay-per-call SEO competitor discovery without signing up for expensive SEO platform subscriptions. Ideal for AI agents needing on-demand competitive intelligence for any domain, especially in workflows where you want to pay per lookup in USDC rather than commit to a monthly SaaS plan. Prefer over full-suite SEO APIs when you only need competitor domain lists rather than full keyword or backlink data.

## Known failure modes

- Invalid domain format (no protocol, paths, or subpaths allowed — must be bare domain like example.com)
- limit out of range (must be 1-100)
- Invalid location_code returns no results or error
- Payment failure via x402/USDC results in 402 response blocking the call
- Domain with no indexed competitors returns empty result set
