## 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 hermes-agent-toolkit-search-778a18ef -d '<json body>'
```

Example prompt: Can you search the web for the latest Ethereum news, check the current ETH price and trading signals, and also scan this Solidity contract snippet for security vulnerabilities all at once?

## When to prefer this

Choose this endpoint when you need a combined web search, crypto price lookup, trading signal, and code security check in a single API call rather than making separate requests to dedicated providers. Useful for agent workflows that need multi-domain data cheaply per call.

## Known failure modes

- Payment not received — endpoint requires $0.02 USDC via x402 protocol before processing
- Invalid or malformed query body returns error response
- Code snippet too large or malformed input rejected
- Cryptocurrency symbol not recognized returns empty price data
- Service unavailable or timeout from underlying data providers

## How this service works

The only x402 API with thin-slicing behavior analysis (80%+ accuracy). Code security + web search + crypto prices + trading signals.

## Output

Returns web search results, current cryptocurrency prices, trading signals, code security findings, and a behavior analysis confidence score (claimed 80%+ accuracy) for the submitted query or code.
