## 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 agentindex-agent-claim-verification-7ed68b78
```

Example prompt: Submit my agent at https://agent.example for verification on AgentIndex under the name 'MyResearchAgent' using a POST method, and get me back a trust badge and operational score.

## When to prefer this

Use this endpoint when you need to formally register and verify an AI agent or API endpoint on the AgentIndex registry, obtain a hosted trust badge, and get an operational score and listing entry. Prefer this over manual directory submissions when you need machine-readable verification results with expiry timestamps and a shareable badge URL, especially in x402/USDC pay-per-call agent ecosystems.

## Known failure modes

- URL is unreachable or returns non-2xx — verification fails or score is low
- Invalid or missing URL field — 400 bad request
- Agent URL is not publicly accessible — cannot verify operational status
- Payment of $0.01 USDC not provided or rejected — 402 payment required
- Method enum value not recognized — schema validation error
