FAQ from X402mail - Email API with crypto micropayments

How does payment work?

Each API call is paid with USDC on Base. Costs are fixed per action (e.g., send email: $0.005, list messages: $0.002). $1 USDC covers approximately 200 emails.

What wallets are supported?

The recommended setup is a Coinbase Developer Platform (CDP) Server Wallet, which requires CDP API keys. You can also use any EVM wallet with USDC on Base by providing a private key.

Do I need an API key?

No. X402mail does not require traditional API keys. For CDP wallet usage, you need CDP API credentials (key ID, secret, wallet secret). For private key usage, you only need an EVM private key.

How much does it cost per action?

Send email: $0.005, check inbox: $0.001, list messages: $0.002, read message: $0.001. All costs are fixed in USDC on Base.

Is there an MCP server for AI agents?

Yes. Run x402mail mcp to start a local MCP server. It provides tools like send_email, get_inbox, list_messages, and read_message. Configure it in your MCP client (e.g., Claude Desktop, Cursor) using the provided JSON block.
