## 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-tools-gateway-bdc4536d -d '<json body>'
```

Example prompt: Use Toll402 to call a tool from its 2,000+ aggregated x402 services — route my request to the business directory lookup capability and pay automatically in USDC from my Base wallet, no API key needed.

## When to prefer this

Choose Toll402 when your AI agent needs to access multiple heterogeneous tools without managing separate API keys or accounts, and when you want to pay per call in USDC via x402 on Base. Ideal for agents that need a single wallet and single endpoint to cover a wide range of capabilities including web access, business lookup, news aggregation, and RSS parsing. Prefer this over individual tool APIs when minimizing integration overhead and credential management is a priority.

## Known failure modes

- Insufficient USDC balance causes 402 payment failure
- Invalid or unknown capability identifier returns routing error
- Underlying tool service unavailable returns downstream error
- Malformed request payload causes 400 bad request
- x402 payment header missing or malformed causes authentication 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 response from the underlying tool or aggregated service that was invoked — this could be structured data, search results, business listings, feed items, or any other capability output depending on which tool was routed through the gateway. Payment is deducted per call via x402.
