## 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-7c94b501 -d '<json body>'
```

Example prompt: Use Toll402 to call a weather lookup tool for New York City right now — charge my USDC wallet per call, no API key needed.

## When to prefer this

Choose Toll402 when your AI agent needs to access many different capabilities without managing multiple API keys or service accounts — especially when you want per-call USDC micropayments via x402 protocol, or when you need a single wallet and gateway to cover a broad set of aggregated tools including web, data, and business directory services.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Unknown or invalid tool identifier returns routing error
- Underlying x402 service is unavailable causing downstream failure
- Malformed tool parameters result in execution error from target service
- Payment facilitator timeout causes transaction failure

## 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 output of the dispatched tool or capability as determined by the underlying x402 service — could be structured data, text, search results, enrichment data, or any other capability output depending on which tool was routed to.
