## 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 grokzilla-seo-skill-x402-micropayment-microservice-5ca00289 -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call SEO analysis without a subscription, especially in agent workflows that require autonomous micropayment-gated API access via the x402 protocol on Coinbase/Stripe rails. Ideal for agents that process many pages at low cost ($0.012 per call) and need structured JSON SEO results programmatically.

## Known failure modes

- Payment not included or invalid — returns HTTP 402 requiring x402 micropayment
- Malformed input body — missing required 'type' or 'method' fields returns validation error
- Unsupported HTTP method or path — may return 404 or error JSON
- Upstream SEO processing failure — may return ok: false with error detail
- Network timeout if SEO computation takes longer than expected
