## 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 agents-get-paid-kit-solve-captcha-x402-usdc-232190b5
```

Example prompt: I need to solve a CAPTCHA on a page I'm trying to access — use the x402 USDC metered solver with a GET request, and make sure spend caps are applied.

## When to prefer this

Choose this endpoint when your AI agent needs to programmatically solve CAPTCHAs and can pay per-solve in USDC via the x402 protocol on Base mainnet, particularly when spend cap enforcement, AUP compliance, and MCP-native tooling are required. It is especially suited to agents already operating within the x402 micropayment ecosystem and needing a metered, policy-governed unlock capability rather than a flat-rate or subscription CAPTCHA service.

## Known failure modes

- Payment not settled — agent lacks sufficient USDC balance on Base mainnet
- Spend cap reached — tool refuses to execute further solves within the cap period
- AUP violation — request blocked due to unacceptable use policy
- CAPTCHA type unsupported — tool cannot handle the specific challenge presented
- x402 handshake failure — payment protocol negotiation fails between agent and endpoint
- Invalid input schema — missing required 'type' or 'method' fields returns a validation error
