## 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-cf188d6e -d '<json body>'
```

Example prompt: Use the Toll402 gateway to call the business directory tool and find me verified coffee shops in Austin, Texas — charge my USDC wallet per call, no API key needed.

## When to prefer this

Choose this endpoint when your agent needs access to a broad catalog of tools (business directories, RSS parsers, HN feeds, web services) without managing individual API keys or signing up for multiple providers. Ideal when you want a single wallet-driven, pay-per-call interface for diverse capabilities using USDC on Base via x402.

## Known failure modes

- Insufficient USDC balance triggers HTTP 402 payment failure
- Unknown or malformed capability identifier returns an error
- Underlying x402 service timeout causes gateway timeout response
- Invalid tool parameters cause a 400-level error with details
- Capability not found in the aggregated catalog returns a not-found error

## 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 structured output from whichever underlying tool or x402 service was invoked — could be business listings, RSS items, news stories, verification results, or any other capability in the 2,000+ service catalog. Payment is deducted per call in USDC via HTTP 402.
