## 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-gateway-ai-agent-tool-hub-4b0e2c07 -d '<json body>'
```

Example prompt: Use Toll402 to call the best available tool for getting current weather in Tokyo — pay per call via my USDC wallet, no API key setup needed.

## When to prefer this

Choose Toll402 when an AI agent needs access to a broad and diverse set of tools or services without the overhead of managing multiple API keys, accounts, or payment methods. Ideal for autonomous agents that dynamically select capabilities at runtime and need a single unified wallet-based payment mechanism via x402/USDC.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Unknown or unavailable tool identifier returns an error
- Malformed tool parameters cause downstream service rejection
- Rate limiting or tool unavailability from underlying provider
- Network timeout from proxied third-party service

## 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 tool or service was invoked — this varies by capability but is delivered through the Toll402 gateway as the unified response payload, eliminating the need to integrate each service separately.
