## 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-aggregator-cac835cb -d '<json body>'
```

Example prompt: Route this tool call through Toll402's gateway — I need it to look up business directory info and pay the per-call fee in USDC from my x402 wallet, no API key setup needed.

## When to prefer this

Choose this endpoint when your AI agent needs to access many different tools or capabilities without managing separate API keys or accounts for each provider, and when you want a unified per-call USDC micropayment model via x402. Ideal for autonomous agents that require dynamic tool selection across a broad catalog of 2,000+ services.

## Known failure modes

- Insufficient USDC balance in x402 wallet returns a 402 Payment Required error
- Unknown or unsupported tool name results in a routing error
- Malformed request payload causes a 400 Bad Request response
- Underlying tool/service provider is unavailable, returning a gateway timeout or 503
- Invalid x402 payment header leads to authentication/payment rejection

## 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 agent receives the output of the dispatched tool or service call — structured results, data, or content from the underlying capability — along with any metadata about the execution, billed at $0.00115 USDC per call via x402.
