## 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 toll402-aggregated-x402-tool-gateway-8ac5e885 -d '<json body>'
```

Example prompt: Use Toll402 to call any of its 2,000+ aggregated x402 services for me — I need to look up a verified business in the global directory, and I want to pay per call in USDC with no API key setup.

## When to prefer this

Choose Toll402 when an AI agent needs access to a broad set of tools or services without the overhead of managing multiple API keys, accounts, or payment methods. It is ideal for agentic workflows that require dynamic tool selection across many capability domains, all billed conveniently per call in USDC via the x402 protocol.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Unknown or invalid service identifier returns routing error
- Downstream x402 service unavailable causes timeout or 503
- Malformed tool call parameters rejected with 400 error
- Payment authorization failure if wallet not properly configured

## How this service works

The OpenRouter for AI-agent tools: one gateway, one wallet, every capability. Built-in tools, forged tools, a global verified business directory and 2,000+ aggregated x402 services, all paid per call in USDC via x402 (HTTP 402). No signup, no API key.

## Output

The response from whichever underlying x402 service or built-in tool was invoked — could be structured data, a directory result, a validation outcome, or any other tool output depending on the specific capability called. The gateway transparently returns the downstream service's result after processing the USDC micropayment.
