## 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-deep-research-json-a0c5dd3b
```

Example prompt: Fetch the deep research JSON for the LION asset — pay the x402 micropayment in USDC on Base and give me the attested resolved status and full data payload.

## When to prefer this

Choose this endpoint when you specifically need attested, structured research data for the LION digital asset and are operating in an autonomous agent context that supports the x402 micropayment protocol with USDC on Base. It is distinct from generic crypto data APIs because it provides keyless attestation and is designed for machine-to-machine agent payments without API key management.

## Known failure modes

- Payment not included or insufficient USDC — returns HTTP 402 with x402 payment requirements
- Invalid or missing x402 payment header — request rejected before data is returned
- Asset not found or not yet resolved — resolved field returns false
- Cloudflare Worker downtime — 5xx error with no payload
- Network timeout on Base payment confirmation — request hangs or times out

## How this service works

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

## Output

A JSON object containing at minimum an asset_id field (e.g. 'LION') and a resolved boolean, plus any additional attested deep-research fields provided by the LION data service. The response is cryptographically attested and delivered after successful x402 USDC micropayment on Base.
