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 requested tool or aggregated x402 service — could be structured data, a lookup result, enriched information, or any capability result depending on which underlying tool was invoked, delivered as a JSON response after successful USDC micropayment via x402.
Example use cases
Crypto-native agent tool routing
“I want my AI agent to be able to call any tool from Toll402's catalog — things like business lookups, data enrichment, and web access — all paid automatically in USDC per call without me setting up separate API keys for each service.”
Accessing verified business directory
“Can you look up verified business information using the Toll402 gateway? I don't have an API key set up anywhere — just pay per call in USDC through their x402 system and get me the result.”
Single wallet multi-tool agent workflow
“My agent needs to chain several capabilities — maybe a web search, some data enrichment, and a lookup — all from one gateway. Use Toll402 so we only need one wallet and pay as we go in USDC on Base.”

Endpoint
POSThttps://toll402.dev/v1/x/3becb5b085ffWhen to prefer
Choose this endpoint when you need a single gateway to access a wide variety of AI-agent tools and x402 services without managing multiple API keys or subscriptions. It is ideal for agents that need to pay per call in USDC on Base, want access to 2,000+ aggregated capabilities including a verified business directory, and prefer a no-signup, crypto-native payment model over traditional API key billing.
Side effects
- Insufficient USDC balance causes HTTP 402 payment failure
- Requested tool or service not found in the aggregated catalog
- Invalid tool parameters cause a 400 bad request
- Network or downstream service unavailability causes 503
- x402 payment header malformed or missing causes authentication failure
