How this service works
Luhn checksum validation (credit cards, IMEI)
Output
Returns a boolean or pass/fail result indicating whether the submitted number string satisfies the Luhn checksum algorithm, used to detect common transcription errors in credit card numbers and IMEI identifiers.
Example use cases
Pre-charge credit card validation
“Before I attempt to charge this card, can you run a Luhn check on 4111111111111111 to make sure it's a structurally valid card number?”
IMEI number verification
“I need to verify if this IMEI number 490154203237518 is valid — can you run it through the Luhn algorithm?”
Detect user input typo in card number
“A customer entered the card number 1234567890123456 on our checkout form — can you Luhn-validate it to see if they might have made a typo?”

Endpoint
POSThttps://x402render-u5vwpxpyua-uc.a.run.app/validate-luhnWhen to prefer
Choose this endpoint when you need a lightweight, instant Luhn checksum validation for credit card numbers or IMEI identifiers without integrating a full payment processor or carrier lookup. Ideal for client-side pre-validation before submission to a payment gateway, or for verifying device identifiers in bulk.
Side effects
- Non-numeric characters in the number string causing validation failure
- Empty string input returning an error
- Number string with spaces or dashes not being normalized before validation
- Service unavailable or payment failure returning a non-200 response
