How this service works
Email validation API. Checks whether a string is a syntactically valid email address using the same production-grade validation library trusted across the Node.js ecosystem, catching edge cases a quick regex misses. Returns true or false.
Output
A boolean value — true if the input string is a syntactically valid email address, false if it is not. No additional metadata or error details are returned beyond the pass/fail verdict.
Example use cases
User registration form validation
“Before I save this new user to the database, can you verify that 'alice@company.org' is actually a valid email address?”
Bulk import data quality check
“I have a customer record with the email 'not-an-email@@broken' — can you confirm whether that's a valid email format so I know whether to reject it?”
Chatbot lead capture validation
“A user just typed 'bob.smith@' into our lead form — can you check if that's a properly formatted email before we try to send them a confirmation?”
Technical details
Endpoint
POSThttps://ppu43fkyhimq5fiqpmo42eh5ri0yypid.lambda-url.us-east-1.on.aws/isEmailWhen to prefer
Use this endpoint when you need production-grade email syntax validation that catches edge cases a simple regex would miss, especially in Node.js-compatible pipelines or when you want a lightweight, single-purpose microservice without pulling in a full validation library. It is not a substitute for email deliverability or existence checks.
Side effects
- Missing 'value' field in request body returns an error or undefined result
- Non-string input may cause unexpected behavior
- Network timeout on Lambda cold start
- Payment failure (402) if USDC balance is insufficient
- Validation only checks syntax, not whether the mailbox actually exists or is deliverable
