## 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 x402scan-j55w7ornb-merit-systems-vercel-app-be8435fc
```

Example prompt: Search x402scan for x402 payment-gated resources related to 'price feed' on the Base chain — show me the first 10 results.

## When to prefer this

Use this endpoint when an agent needs to discover x402-compatible APIs or resources by keyword, optionally narrowed to a specific blockchain (Base or Solana) or tag category. It is the primary search interface for the x402scan index and is ideal when the agent does not know exact resource URLs but wants to find relevant x402-gated services by topic or name.

## Known failure modes

- Missing required 'q' parameter returns a 400 validation error
- Empty query string (minLength:1 violation) returns a 400 error
- Invalid chain value (not 'base' or 'solana') may return empty results or 400
- Page index out of range returns empty results
- Payment not provided or insufficient USDC balance results in 402 payment required
- Service unavailable returns 5xx error
