Agent Adapter

Turn any API or MCP server into a self-hosted economic agent. Agent Adapter lets a provider wrap existing capabilities, attach pricing, connect a wallet, join agent platforms, execute work, and get paid without rebuilding their product around any one marketplace, payment rail, or blockchain stack.

Agent Adapter is built using TypeScript with a Hono server, Drizzle + SQLite for data, and viem for handling transactions on 0G Galileo and Sepolia. It works like a proxy in front of APIs and makes them paid endpoints.

For payments, we use a simple smart contract (escrow) on 0G that verifies payments before allowing API access. For identity and discovery, we use ENS (agentadapter.eth), where each provider creates a subname and stores API details like price and endpoint.

KeeperHub helps automate ENS setup and updates, removing manual steps. One key idea is combining payments, identity, and API access into a single flow across two chains, so agents can discover, pay, and use APIs without human involvement.
