You Shouldn't Have to Commit to an API Before You've Seen What It Returns
Evaluating a new API is annoying. You read the docs, the docs look reasonable, and then you spend an afternoon finding out whether the actual responses match the promise. Sometimes they do. Often they don’t. Either way, you’ve lost the afternoon.
The worst version of this is when you can’t even start evaluating without signing up, entering a credit card, or picking a pricing tier. Now you’re not just evaluating the API. You’re evaluating whether you trust the company enough to hand over payment information before you’ve seen a single response.
We were doing a version of this with StoaPack. Not the credit card part, but the plan selection part. New accounts could explore the dashboard and read the docs, but couldn’t make an API call until they’d selected a plan. Even a free one. It was a small ask, but It was a small ask, but it was still a commitment before value. That’s the wrong order.
What we changed
New StoaPack accounts now get 50 free API calls the moment they confirm their email. No plan selection, no credit card, no timer counting down.
You create an account, generate a key, and you’re making real API calls within ten minutes. Pack items across multiple warehouses, test your actual inventory data, build a proof of concept. See what the responses look like before you decide whether it’s worth building around.
When you’ve used 40 of your 50 calls, we’ll nudge you toward picking a plan. When you hit 50, the API tells you clearly what happened and where to go next.
That’s it. 50 calls, nothing required upfront, results first.
Why this matters for a packing API specifically
A bin packing API is one of those things that’s hard to evaluate from documentation alone. The interesting questions aren’t “does it support metric units.” They’re things like: how does it behave when inventory at the closest warehouse is insufficient? What happens when an item has fragile handling requirements and the only available box is too large? How does it decide between two warehouses with similar shipping distances?
You can’t answer those questions by reading about them. You have to call the API with real scenarios and see what comes back.
50 calls gives you room to actually do that.
Try it
Sign up, follow the quick-start guide, and make your first call. If the responses are useful, great. If something looks wrong, the docs cover most edge cases. And if they don’t, we’re reachable.
