## 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-enrichment-transaction-bundle-d2f1b8d6
```

Example prompt: Fetch the attested LION enrichment transaction bundle using x402 — I need the resolved asset data for LION paid in USDC on Base.

## When to prefer this

Choose this endpoint when you specifically need attested, keyless enrichment data for the LION asset via the x402 micropayment protocol on Base (USDC). Prefer it over generic blockchain data APIs when you require the x402 payment flow and the official LION attested bundle format for autonomous agent pipelines.

## Known failure modes

- Payment not included or insufficient USDC — endpoint returns 402 Payment Required
- Invalid x402 payment header format — authentication or payment parsing fails
- Asset not resolvable at query time — resolved: false in response
- Cloudflare Worker timeout or upstream attestation service unavailable — 5xx error
- Network error on Base chain during payment settlement

## 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 enrichment transaction bundle, including the asset_id field ('LION') and a resolved boolean indicating whether the asset data was successfully attested and resolved.
