## 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 strale-keyword-rank-check-05279f8f -d '<json body>'
```

Example prompt: Can you check where stripe.com ranks on Google in the US for the keyword 'online payment processing'? Scan the top 50 results.

## When to prefer this

Choose this endpoint when you need a structured, auditable keyword ranking check for a specific domain in a specific market, especially when you need international support (27 countries), validated country/language inputs, and a cryptographic audit trail. Prefer over manual Google searches or generic SEO tools when operating inside an AI agent workflow that requires reliable, machine-readable output with per-call accountability.

## Known failure modes

- Unrecognized country code rejected before search runs and returns a validation error
- Malformed language code (not ISO 639-1) rejected before search runs
- Domain not found within specified depth — returns no rank found rather than an error
- Depth exceeds max of 100 — request rejected
- Missing required fields (keyword or domain) — request rejected with validation error
- Upstream Serper/Google API unavailability causes service error

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns the ranking position of the specified domain in Google search results for the given keyword, along with surrounding search result metadata and a cryptographically hashed audit record for traceability. If the domain is not found within the scanned depth, that is also indicated.
