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 x402-compatible tool or service that was invoked, which may include structured data, text output, lookup results, or enrichment data depending on which capability was routed through the gateway.
Example use cases
Single-wallet multi-tool agent pipeline
“I'm building an AI agent that needs to call several different tools — web search, a business lookup, and a data enrichment service — all in one pipeline. Can you route all of those through Toll402 using my USDC wallet so I don't have to manage separate API keys for each?”
Pay-per-call business directory lookup
“Look up the verified business details for 'Acme Corp' using the Toll402 gateway and charge the $0.00115 per-call fee to my x402 USDC wallet — I just need their canonical business info without signing up for a separate directory API.”
On-demand Wikipedia summary via x402
“Fetch me a summary and canonical URL for the Wikipedia article on 'quantum entanglement' through the Toll402 x402 gateway, paying per call from my USDC balance — no API key, just route it through the aggregator.”
Technical details
Endpoint
POSThttps://toll402.dev/v1/x/683043dfa1feWhen to prefer
Choose Toll402 when you need to access a wide variety of AI-agent tools or x402 services from a single gateway without managing separate API keys, accounts, or billing relationships — especially when operating in a crypto-native environment where USDC micropayments per call are preferable to subscription billing. Ideal for autonomous agents that need flexible, pay-as-you-go access to 2,000+ aggregated capabilities.
Side effects
- Insufficient USDC balance in wallet causes payment failure and 402 response
- Unknown or invalid capability identifier returns a routing error
- Underlying service is unavailable or returns its own error code
- Network timeout from the downstream x402 service
- Malformed request body causes a 400 validation error from the gateway
