AgentBIT
Pay-per-call API tools for AI agents, monetized with the x402 protocol
AgentBIT is a catalog of ~99 HTTP API tools (AI, business, finance, security, data, onchain, and more) that AI agents can call without signup or API keys. Each endpoint uses the x402 protocol: a request returns HTTP 402 with the price, payment is made in USDC on Base (eip155:8453), and the call is retried with an X-PAYMENT header. Tools are also exposed via an MCP server and OpenAPI spec, and AgentBIT indexes x402 tools from other marketplaces (Coinbase Bazaar, Agent402, Agentic Market) with free discovery and a paid routing/execute endpoint.
