## 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 lion-x402-enrich-v1-json-26338d39
```

Example prompt: Look up the attested enrichment data for asset ID 'LION' and return the resolved JSON record — pay the micropayment automatically via x402 on Base.

## When to prefer this

Choose this endpoint when you need keyless, attested enrichment data for the LION asset and want to pay automatically via the x402 USDC micropayment protocol on Base — no API key registration required. Prefer it over traditional enrichment APIs when operating as an autonomous agent that can self-pay for data access in a trustless, permissionless flow.

## Known failure modes

- Payment not received or x402 handshake fails — endpoint returns 402 Payment Required
- Invalid or unrecognized asset_id — resolved may return false or endpoint returns 404
- Cloudflare Worker timeout or downtime — returns 5xx error
- Malformed request parameters — returns 400 Bad Request
- Insufficient USDC balance on Base for micropayment — payment fails silently or with error

## How this service works

Keyless attested data for autonomous agents. USDC on Base via x402. Official @x402/* middleware.

## Output

A JSON object containing the asset_id field and a resolved boolean (e.g. {"asset_id":"LION","resolved":true}), plus any attested enrichment metadata associated with the queried asset identifier.
