Description
x402 Facilitator is a payment settlement service on Abstract that enables AI agents and applications to transact using the x402 HTTP payment protocol. It verifies signed stablecoin payment authorizations and settles transactions on-chain, allowing HTTP servers and APIs to require per-request USDC payments without API keys or traditional billing infrastructure. The service runs as a public, gas-sponsored facilitator on Abstract mainnet and testnet, supporting any ERC-3009-capable token.
