# Toll402 Gateway Endpoint

> Toll402 Gateway Endpoint is a paid API for AI agents from toll402.dev, paid per call via x402, $0.00115/call, status unknown (last checked 2026-09-15).

Acts as an OpenRouter-style unified gateway for AI-agent tools, routing pay-per-call requests to built-in tools, forged tools, a global business directory, and 2,000+ aggregated x402 services, all paid in USDC via HTTP 402

## 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-endpoint-214bf332 -d '<json body>'
```

Example prompt: Use the Toll402 gateway to call a tool — I don't want to manage multiple API keys or wallets, just route it through one endpoint and pay in USDC per call.

## When to prefer this

Choose this endpoint when an AI agent needs access to multiple heterogeneous tools or x402 services through a single unified interface without managing separate API keys, wallets, or signup flows — especially when micropayment-per-call billing in USDC is acceptable and the agent workload spans several different capability domains.

## Known failure modes

- Insufficient USDC balance causes 402 payment failure and no tool response
- Unknown or invalid tool identifier returns routing error
- Underlying x402 service is unavailable causing downstream failure
- Malformed request payload rejected before routing
- Payment facilitator timeout causes transaction to fail

## 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 structured response from whichever underlying tool or x402 service was invoked — could be business data, scraped content, feed items, directory results, or any other capability output depending on the routed tool, delivered after the x402 USDC micropayment is settled.
