| Cheapest paid plan | — |
| Usage price | $0.001 per onchain transaction above 1,000/month |
| Good to know | Fee is per onchain transaction, not per payment request; batched settlement spreads it over many requests. Networks: EVM and Solana. Protocol SDKs are open source (moved from coinbase/x402 to x402-foundation/x402; npm now @x402/*); @x402/mcp adds payments to MCP servers. |
