Email Verification API

A straightforward email validation service that checks syntax, MX records, and flags disposable addresses, then returns a quality score from 0 to 100. Runs as a remote MCP server over SSE and charges per verification using x402 micropayments in USDC. You'd reach for this when your agent needs to validate user input or clean email lists without spinning up your own infrastructure. The repository shows it's built in TypeScript and deployed at email-verification.api.klymax402.com, though the actual MCP tools and prompts aren't documented in the source. The micropayment model means you pay only for what you use rather than maintaining an API subscription.
