How this service works
Machine-facing pay-per-call utility services using x402 on Base with USDC.
Output
Returns a JSON object containing the original email, the extracted domain, the normalized canonical form of the email, and a boolean indicating whether the syntax is valid.
Example use cases
New user registration email check
“Before I save this new user to my database, can you validate their email 'john.doe@company.org' and confirm it's properly formatted and give me the normalized version?”
Bulk lead list quality gate
“I'm about to send a campaign — can you check if 'marketing_lead@corp.co' is a valid email and pull out its domain so I know what company it's from?”
Form input sanitization
“A user just typed 'Jane+filter@Gmail.COM' into my signup form — can you validate and normalize that email address so I store the clean version?”
