# LION x402 Adaptive Query

> LION x402 Adaptive Query is a paid API for AI agents from lion-x402-bible.lionmaster-operations.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns keyless attested data for a given query using adaptive resolution modes (auto, rpc, domain, social) via x402 micropayment on Base USDC.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-adaptive-query-40950304
```

Example prompt: Look up attested on-chain data for the LION asset using auto mode — I need to know if it resolves and what the asset ID comes back as.

## When to prefer this

Choose this endpoint when an AI agent needs keyless, attested on-chain data about a crypto asset, domain, or social identity on Base, and can pay $0.005 USDC per call via the x402 protocol. Particularly useful when you need adaptive resolution across multiple data modes (RPC, domain, social) without managing API keys.

## Known failure modes

- Payment not accepted — 402 returned if USDC micropayment not included or insufficient
- Invalid mode value — must be one of auto, rpc, domain, social
- Missing required 'q' query parameter — returns validation error
- Query fails to resolve — resolved: false returned with partial or empty payload
- Network or worker timeout on Cloudflare edge

## 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' string (e.g. 'LION') and a 'resolved' boolean indicating whether the query successfully resolved, plus any additional attested data fields returned by the adaptive resolution pipeline.
