MESH Gateway MESH

MeshGateway is a machine payments gateway on Robinhood Chain. It implements the Machine Payments Protocol (MPP, an HTTP 402 payment flow) so that AI agents and automated software can pay for API calls in USDG, the Global Dollar stablecoin, without accounts, API keys, or subscriptions. A client requests an endpoint, receives a 402 challenge with a price, signs a USDG payment authorization, and receives the response once the payment settles on-chain. The platform includes a marketplace of paid API endpoints operated by independent merchants, open-source client and server SDKs on npm, an ERC-8004 agent identity registry (MeshIdentity), and virtual payment cards funded with USDG (MeshCard). MESH is the protocol's token: protocol fees collected from settled payment volume are pooled and distributed daily in USDG to qualifying MESH holders.
