OpenFacilitator (OPEN)

OpenFacilitator is a hosted x402 payment facilitator service that enables developers to accept x402 payments without running their own infrastructure. The x402 protocol allows AI agents and applications to make autonomous micropayments for APIs and web resources. OpenFacilitator offers a free public endpoint at pay.openfacilitator.io, or users can create their own white-labeled facilitator for $5/month with custom domain support. The service is non-custodial, supports EVM chains and Solana, and is fully open source under Apache 2.0.
