Building API Clients Faster with apiexplorer.io and Martini
One thing I’ve learned after years of working with enterprise APIs: most integration projects don’t fail because of code—they fail because of friction.
Too much time wasted digging through incomplete documentation. Too much trial and error to figure out how APIs actually behave. Too many moving parts slowing developers down before they even hit “Run.”
That’s exactly why we built apiexplorer.io at Lonti—and why I use it myself every time I want to get a head start on a new integration or workflow.
If you haven’t checked it out yet, let me show you how I—and plenty of other developers—use apiexplorer.io and Martini to go from idea to working prototype, fast.
Why We Built apiexplorer.io
At Lonti, our mission is pretty straightforward: give professional developers low code, no limits tools to solve real problems.
And let’s be honest—one of the biggest headaches in integration is simply figuring out how different systems’ APIs behave before you commit to the build. You’re stuck with:
- Sparse or outdated API docs
- No usable test environments
- A ton of upfront effort just to test basic use cases
We wanted to eliminate that friction.
That’s why apiexplorer.io isn’t just another demo API. It’s a fully-loaded suite of enterprise-grade APIs—Billing, CRM, Ecommerce, Financials, Inventory, Payments, and more—designed specifically for developers to prototype integration projects easily.
Each API comes with:
- Comprehensive API documentation
- OpenAPI specs
- Pre-built Postman collections
- A real front-end UI to visualize data
- And of course, an interactive API Explorer UI
All you need to get started is a free signup—you’ll get your API access key instantly, no delays, no hoops.
How I Prototype Integrations with apiexplorer.io + Martini
Here’s how I personally use apiexplorer.io to cut through the noise and get straight to building.
Step 1: Grab an API Access Key
Sign up free at apiexplorer.io, get your API key immediately, and you’re ready to start hitting any of the APIs in the catalog.
Step 2: Pick the APIs You Want to Integrate
Say I’m working on an integration between a CRM system and a Payments provider. I’ll select the CRM API and Payments API from the Explorer. Right there, I can:
- Browse API endpoints
- Test them live
- Understand the payloads
- See how the front-end application interacts with the APIs
No ambiguity. No surprises. Everything behaves like it should.
Step 3: Import into Martini
Here’s where it gets fun.
I fire up Martini—our API integration and automation platform—and import the OpenAPI specs from apiexplorer.io. Martini’s low-code API client builder takes care of the heavy lifting, generating the service connectors and data models.
What’s left? Just the logic.
Step 4: Build and Automate the Workflow
Using Martini’s visual workflow editor, I can wire up the CRM’s “New Customer” event to trigger a Payments API call, maybe automate invoice creation, notifications, whatever I want.
Need data transformations? Martini’s got built-in mapping.
Want custom business rules? Drop in Groovy or Java, no limits.
In under an hour, I’ve got a functioning integration prototype—and because it’s built with real, working APIs, I can confidently move forward, knowing there won’t be nasty surprises later.
Why Developers Love It
Here’s why apiexplorer.io paired with Martini is a game-changer:
- Real, fully functional APIs that reflect real enterprise systems.
- No guessing games—every API has documentation, an Explorer, a front-end UI, and sample data.
- Free signup, instant API key. Zero friction to get started.
- Seamless integration with Martini’s low-code tools, but always flexible enough for pros to customize.
We built apiexplorer.io because we wanted a better, faster way to prototype integrations—not just for our customers, but also for our team at Lonti.
What’s Next?
Once you’ve got your prototype working:
- Swap apiexplorer.io endpoints for production systems.
- Scale the workflow, add error handling, expand functionality.
- And if you’re building an app on top of those APIs, you can jump into Bellini and design your front-end, all API-powered.
TL;DR
Stop wasting time fighting bad docs or guessing how APIs behave.
Sign up free at apiexplorer.io, grab your key, and start prototyping today.
Use it with Martini, and you’ll be building real integrations before lunch.
I use it. Our team uses it. And I promise—it’ll change how fast you move.
