What this does

• Browse 2,800+ APIs across data, AI, finance, and utilities
• Call any API directly — payment handled automatically via x402 on Base
• No API keys — agents pay per call in USDC, no accounts needed

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.
