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 invoked tool or service — e.g. data lookups, enriched records, search results, or capability-specific payloads — depending on which underlying tool or aggregated x402 service was dispatched.
Example use cases
Unified tool invocation for agent
“I want my agent to call any tool it needs — web search, data lookup, or enrichment — through a single gateway without managing dozens of API keys. Use Toll402 so everything is billed in USDC per call automatically.”
Business directory lookup via x402
“Look up the verified business details for 'Acme Logistics Inc' using Toll402's global verified business directory — I need their address and contact info, paid per call in USDC.”
Aggregated capability routing
“My agent needs to pick the right tool from Toll402's 2,000+ aggregated x402 services to geocode an address and return coordinates — route the request through the Toll402 gateway and pay in USDC.”

Endpoint
POSThttps://toll402.dev/v1/x/a6d18263bb67When to prefer
Choose this endpoint when an AI agent needs to call any of a large catalog of tools or services without managing multiple API keys or accounts — especially when the agent has a USDC wallet and wants pay-per-call billing via x402. Prefer this over direct API integrations when operational simplicity and unified billing matter more than direct provider relationships.
Side effects
- Insufficient USDC balance or failed x402 payment results in HTTP 402 with payment required error
- Unknown or unsupported tool name returns 404 or error payload
- Malformed tool parameters return a 400 validation error
- Underlying third-party service unavailable causes 502 or timeout
- Rate limiting on downstream service returns an error code
