IsValid is a validation API service for developers who need to quickly verify data formats without building their own validators. It offers 40+ endpoints covering financial identifiers (IBAN, BIC, ISIN, CUSIP), international standards (ISBN, ISSN), technology formats (UUID, JWT, QR codes), regional codes (PESEL, REGON, VAT), and more.

The service works on a freemium model โ€” 100 free API calls per day, no credit card required. Users manage API keys through a dashboard with usage analytics showing daily call volume and per-endpoint breakdowns.

Questions & Answers

As answered by people managing UXpin and IsValid.dev.

What makes your product unique?

IsValid.dev's answer:

IsValid offers 70+ validators in a single API โ€” covering financial identifiers (IBAN, BIC, ISIN, LEI), international standards (ISBN, ISSN), technology formats (UUID, JWT, QR codes), tax numbers (VAT, REGON, PESEL), credit cards, phone numbers, and more. No need to integrate multiple services for different data types.

Why should a person choose your product over its competitors?

IsValid.dev's answer:

Most validation APIs focus on one category (email or phone). IsValid covers financial, regional, and technical formats all in one place with a consistent REST API. The free tier with 100 calls/day requires no credit card, and integration takes minutes.

How would you describe the primary audience of your product?

IsValid.dev's answer:

Developers and software teams building applications that handle user input, financial data, or international identifiers โ€” particularly in fintech, e-commerce, and SaaS products.

What's the story behind your product?

IsValid.dev's answer:

IsValid was built out of frustration with piecing together multiple validation libraries and services. The goal was a single, reliable API that handles the full range of data validation needs developers encounter in real-world applications.

Which are the primary technologies used for building your product?

IsValid.dev's answer:

Next.js, Fastify, PostgreSQL, Docker

  • Another newbie question, I want to build a PWA, I thought bootstrap + Django would be enough. I understand I still need Javascript, I think I'm going with VueJS but I'm getting lost on what I'm doing in which framework. Details in post ๐Ÿ˜ฌ ๐Ÿ‘†๐Ÿป
    1st design a responsive website from templates that follow established design: UXPin.com . Most of the other prototyping solutions kinda felt like they're built for folks who can draw, sketch, or maybe organize their room and choose matching clothes. Not me. Not a designer, I can barely choose my own clothes, let alone design something. I can think in components though. I especially liked their storybook example.... Source: over 4 years ago
