## 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 public-canonical-hreflang-indexing-directives-inventory-purchase-91db78c0 -d '<json body>'
```

Example prompt: Can you kick off a canonical, hreflang, and indexing directives inventory scan for example.com and give me the job ID so I can check results when it's done?

## When to prefer this

Use this endpoint when you need to programmatically audit a website's canonical URL declarations, hreflang language/region targeting tags, and indexing directives (noindex, nofollow, canonical) via an AI agent marketplace with micropayment billing. Prefer this over scraping tools when you want a managed, asynchronous job with tracked results and no infrastructure overhead.

## Known failure modes

- Payment not authorized — 402 response if USDC payment is not properly included
- Invalid service ID — 404 if svc_9f42983e0b5242a9 is not recognized
- Malformed request body — 400 if required fields are missing
- Payment amount insufficient — rejected if less than $0.053 USDC is provided
- Service temporarily unavailable — 503 during platform downtime
