## 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-composite-bundle-json-125310bc
```

Example prompt: Fetch the LION composite data bundle from the LION x402 seller — pay the $0.001 USDC fee on Base and give me the attested JSON with the resolved asset info.

## When to prefer this

Choose this endpoint when an autonomous agent needs keyless, attested asset data for the LION asset and can pay $0.001 USDC per call via the x402 micropayment protocol on Base — ideal when avoiding traditional API key management and needing cryptographically attested, machine-readable JSON output.

## Known failure modes

- Payment not included or insufficient USDC: returns HTTP 402 Payment Required
- Invalid or expired x402 payment header: authentication rejected
- Cloudflare Worker timeout or downtime: 5xx error
- Malformed request missing required headers: 400 Bad Request
- Base network congestion causing payment verification delay

## How this service works

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

## Output

A JSON object containing the LION asset identifier (asset_id: 'LION') and a resolved boolean, along with additional attested composite data fields confirming the asset's status as provided by the LION x402 seller.
