How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with a boolean 'ok' indicating whether the email is syntactically valid, the 'local' part (before the @), the 'domain' part (after the @), and a schema identifier string. No network lookup or mailbox verification is performed — purely structural/syntactic analysis.
Example use cases
Form input validation before submission
“Before I save this user's profile, check if the email address they typed — 'jane_doe@mycompany.org' — is syntactically valid.”
Batch lead list pre-screening
“I have a lead email 'bad@@broken..com' — can you tell me if that's a valid email format before I try to add it to my CRM?”
Email parser for automated workflows
“Parse 'support+ticket123@helpdesk.example.io' into its local part and domain so I can route it to the right team.”
