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 output of the dispatched tool — this varies by capability called but may include data lookups, transformed content, search results, business directory entries, or computation outputs. Responses are returned inline with x402 payment confirmation.
Example use cases
Live exchange rate lookup for agent
“I need my agent to convert 500 EUR to USD — can you use Toll402 to grab the current ECB exchange rate and do the conversion without me setting up a separate API account?”
GitHub repo stats for due diligence
“Pull the stars, forks, open issues, license, and last push date for the repo github.com/openai/openai-python using Toll402 — just pay per call, I don't want to bother with GitHub API tokens.”
Multi-tool autonomous agent workflow
“My agent needs to look up a business, check current currency rates, and fetch some web data all in one session — route everything through Toll402 so I only need one wallet and pay per call in USDC.”

Endpoint
POSThttps://toll402.dev/v1/x/26f6d7af960bWhen to prefer
Choose Toll402 when your AI agent needs access to many different tools or capabilities without managing per-service API keys or subscriptions. It is especially suited for agents that require pay-per-call micropayment economics in USDC via the x402 protocol, want to avoid upfront signup friction, or need to dynamically discover and invoke capabilities from a large aggregated marketplace of 2,000+ services.
Side effects
- Payment failure or insufficient USDC balance results in 402 response with payment required details
- Unknown or unsupported tool name returns an error indicating no matching capability
- Upstream tool provider downtime causes propagated errors or timeouts
- Malformed input parameters for the target tool return validation errors
- Rate limits on underlying aggregated services may cause transient failures
