# TOLL·402

> The directory of x402-payable tools for AI agents — MCP servers and APIs that charge per call in USDC over the x402 protocol (HTTP 402, on Base). No accounts, no API keys: your agent pays, the call runs.

Each listing shows kind, network, status, and price. "verified" means TOLL·402 made a real paid call to the endpoint and confirmed on-chain settlement. Prices are what your agent pays the provider directly — there is no platform fee.

## How payment works
An agent calls a tool with no payment and the server answers HTTP 402 with a USDC price quote. The agent signs an x402 payment authorization and retries; the server verifies, runs the tool, and settles on-chain. Gasless for the payer via EIP-3009.
