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 service, which varies by the underlying capability invoked. Could include structured data, business records, enriched information, computation results, or other tool-specific payloads, all routed through the Toll402 gateway after successful x402 USDC micropayment on Base.
Example use cases
Business directory lookup via agent
“Search the Toll402 verified business directory for coffee shops near downtown Austin and return their contact details — pay per call using my x402 wallet.”
No-signup tool access for agent pipeline
“I need my AI agent to access web search and data enrichment tools without setting up any API keys — route everything through Toll402 and pay per call in USDC.”
Aggregated capability routing for multi-tool agent
“My agent needs to call several different capabilities — a geocoding service, a weather lookup, and a business enrichment tool — can Toll402 handle all of those through one gateway with micropayments?”
