## 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 claw402-rootdata-search-via-x402-payment-gateway-5aa59dbe
```

Example prompt: Search RootData for 'Uniswap' and give me whatever project info comes back — pay the $0.002 USDC fee per call, no API key needed.

## When to prefer this

Use this endpoint when you need to search the RootData crypto/Web3 project database without obtaining a traditional API key, and you have a USDC-enabled wallet to pay $0.002 per call via the x402 protocol. Prefer this over direct RootData API access when you want keyless, wallet-native access to Web3 project search data.

## Known failure modes

- Payment not received or insufficient USDC — 402 response requiring payment
- Empty data array returned when query matches no RootData projects
- Invalid query parameter format — missing required 'query' param
- Upstream RootData API unavailable — proxy error or timeout
- Wallet not recognized or x402 handshake fails — payment rejected

## How this service works

Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.

## Output

A JSON object with a code field (0 = success) and a data array containing matching crypto/Web3 project records from the RootData database, including project metadata such as name, description, and related on-chain details.
