APIVerve for Visual Studio
Browse, test, and ship code against 360+ real-world APIs — weather, geocoding, finance, DNS, validation, text, and more — from a dockable tool window inside Visual Studio. Find the API you need, try it with real data, and drop ready-to-run C# into your project.
Browse freely — no account needed
Open View → Other Windows → APIVerve and explore the entire catalog signed out: search, filter by category, read descriptions, view example responses, and copy code. You only sign in when you want to make a live call.
Features
- APIVerve tool window — search the full catalog, filter by category, each API with its logo, description, and method.
- Try any API for real — fill in the parameters, hit Run, and see the actual JSON response, syntax-highlighted, docked right in the IDE. Your remaining credits show in the header.
- Ready-to-run C# — Insert drops a working
HttpClient call at your cursor; Copy C# / Copy cURL put it on the clipboard.
- Every API has a NuGet package — jump straight to it from the detail view.
- See it before you call it — example responses and a link to each API's docs.
- Sign in your way — OAuth or an API key, stored securely; never in your code.
- Self-updating catalog — refreshes from
assets.apiverve.com; a bundled snapshot keeps it working offline.
Getting started
- Open View → Other Windows → APIVerve and start browsing — no sign-in required.
- When you want to run a live call, sign in with APIVerve (or paste an API key). Don't have one? Get a free key from the sign-in screen.
- Pick an API, fill in the parameters, and Run — or Insert the C# into your open file.
New accounts include free credits, so you can start calling APIs right away.
