How payments work

Orbis uses the x402 protocol — an open HTTP payment standard built on Base. When your agent calls an API:

  1. Orbis returns a 402 Payment Required response with payment details
  2. The MCP server handles the USDC payment on Base automatically
  3. The API call completes — total cost: $0.01

No wallets to configure for browsing. To make paid calls, provide your Base wallet via ORBIS_KEY.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
