How this service works
Zach Riehn's lab: an about-me and portfolio, a news desk, The Atelier for AI experiments, Launch Lab for XRP research, and Fracture for games.
Output
Returns a JSON object with a single boolean field `syntax_ok` — true if the provided email address passes syntax validation, false if it does not.
Example use cases
Pre-send email format check
“Before sending out my newsletter, can you verify that 'user@mydomain.co' is a properly formatted email address?”
Form input validation
“A user just submitted 'notanemail@@broken' as their email — is that actually a valid email syntax?”
Database cleanup validation
“I'm cleaning up my user database — can you check if 'jane_smith@company.org' passes basic email syntax validation?”
Technical details
Endpoint
GEThttps://cocoeatsai.com/area4/agent/tools/email-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, cheap ($0.001 USDC) syntax-only email validation check without requiring DNS MX record lookup or deliverability confirmation. Best suited for lightweight pre-validation steps in form processing or data pipelines.
Side effects
- Missing or malformed query parameter may return an error or unexpected result
- No email address provided returns undefined behavior since queryParams schema has no defined properties
- Network or payment failure (402 not satisfied) blocks the request entirely
