## 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-ai-agent-tool-gateway-935bf507 -d '<json body>'
```

Example prompt: Use Toll402 to call any of the 2,000+ aggregated AI-agent tools — just describe what I need done and pay per-call in USDC via x402, no API key needed.

## When to prefer this

Choose Toll402 when you want a single universal gateway to access a broad range of AI-agent tools and x402 services without managing multiple API keys or subscriptions — ideal for agents that need to dynamically route tasks to different capabilities and pay only for what they use in USDC micropayments via x402.

## Known failure modes

- Insufficient USDC balance or failed x402 payment results in HTTP 402 with payment details
- Unknown or unavailable tool requested returns an error indicating the capability is not found
- Tool execution failure returns an upstream error from the underlying service
- Malformed input parameters return a validation error describing required fields
- Network timeout or upstream service outage may return a 503 or timeout response

## 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

Returns the response from whichever underlying tool or x402 service was invoked — could be structured JSON, Markdown text, extracted data, directory listings, validation results, or any other capability output depending on the tool called, all delivered after successful USDC micropayment via x402.
