Browse CollectionHow the APIHiver API marketplace works
- Find an API. Search the marketplace or browse categories such as weather, currency, OCR, email and phone validation, and Indian IFSC, GSTIN and UPI lookups. Every listing shows its endpoints, pricing plans and live service level.
- Test it in your browser. Each endpoint has a built-in playground, so you can send a real request and see the response before you write any code.
- Subscribe and call it. Pick a free plan or a paid one, then use one API key for every API you subscribe to. Usage, request logs and billing live in one dashboard.
- Publish your own. Add your API, describe its endpoints, set plans and prices, and APIHiver handles the key management, rate limits, analytics and payouts.
Why developers use APIHiver
Finding a reliable API usually means reading a dozen docs, signing up on a dozen sites and managing a dozen keys. APIHiver puts them in one place, with a consistent way to try, subscribe, monitor and pay.
- Free APIs and free plans, so you can build and test before you pay.
- Prices in rupees, with simple monthly plans and no hidden per-call surprises.
- Clear metrics on every API: popularity, latency and service level from real traffic.
- A gateway in front of each API that handles authentication and rate limiting for you.
Building an API of your own? Providers keep control of their pricing and are paid monthly. Learn more about APIHiver or read the documentation.
