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.

Environment Variables
