IsValidValidate 70+ data formats with one REST API
Leszek Czajkaleft a comment
I built IsValid out of frustration with integrating multiple validation libraries for different data types. Instead of juggling separate services for IBAN, phone, email, VAT, and UUID validation — IsValid gives you one consistent REST API for 70+ validators. Free tier available (100 calls/day, no credit card). Would love your feedback!
