How this service works
Generate a random Luhn-valid TEST card number for the given network (default Visa). For testing only — these are not issued cards and cannot be charged. The response is always flagged `test:true`.
Output
Returns a synthetically generated payment card number that is valid in format (passes Luhn algorithm) for the specified card network and length, suitable for testing purposes but not a real funded account.
Example use cases
Payment integration testing suite
“Generate a valid-format 16-digit Mastercard number I can use to test our checkout flow in the staging environment.”
American Express QA validation
“I need a synthetic American Express card number — those are 15 digits — to test how our form handles Amex's different length and format.”
Multi-network card format testing
“Can you generate a Discover card number for me so I can verify our payment processor handles all the major networks correctly?”
Technical details
Endpoint
POSThttps://creditcard.openverbs.com/v1/generateWhen to prefer
Use this endpoint when you need syntactically valid, format-correct card numbers for payment system testing, QA, or integration validation — especially when you need numbers for a specific card network (Visa, Mastercard, Amex, Discover, Diners Club, JCB, or UnionPay) or a specific length. Prefer this over hardcoded test card lists when you need dynamic generation or network-specific numbers on demand.
Side effects
- Invalid length for chosen network (e.g. requesting 15 digits for Visa) returns validation error
- Unsupported network name returns enum validation error
- Missing required fields returns 400-level error
- Service unavailable returns 5xx error
- Payment of 0.002 USDC not completed returns 402 Payment Required
