402signalhq/402signal
Checks live x402 routes across Base, Solana, and Algorand. $0.003 USDC settles only for a valid live eligible route; normal typed misses are not settled. Free preview and validate tools. Seller payment is separate; the agent keeps its wallet. Remote MCP: https://402signal.com/mcp (x402-capable client required for paid routing).
