30 structured tests against your own requirements. Fit, Partial Fit, or No Fit. You bring the trial key, KeyKit brings the test harness.
Don't have the week either? Have Mulberry run the evaluation with you.
Define your tolerance for freshness, latency, field fill rate, and reliability. KeyKit runs your data or model API through up to 30 test types and returns Fit, Partial Fit, or No Fit verdicts tied to what you actually need. Use your own trial API key. No provider involvement required.
Run the same evaluation suite across multiple providers and see the results head to head. Built for buyers shortlisting two or three options. Built for providers who want to know where they stand.
Schedule evaluations to run daily, weekly, or monthly. KeyKit alerts you when coverage drops, latency spikes, or field fill rates change. Post-purchase monitoring so you are never caught off guard.
KeyKit aggregates anonymized results across all users testing the same provider. Know immediately whether your results are normal or a red flag, without asking anyone.
Simple mode surfaces the results that matter in plain English: what was tested, what it means for your requirements, and whether the API passed. Advanced mode gives full framework-level control for technical users. Switch between them at any time.

Every framework scores API performance against your stated requirements, not industry averages. It tests whether an API handles the queries your use case actually needs, not just the simple ones in the demo.
Does the dataset cover the time range and regions your use case requires?
Are records complete, canonical, and free of duplicates before they hit your pipeline?
Does re-querying the same parameters return the same results? Critical for incremental pipelines.
How stale is "live" data? We measure actual ingestion lag against your stated tolerance.
Can the API handle the queries your use case actually needs, or only the simple ones in the demo?
Performance and stability under realistic load, not cherry-picked conditions.
Does multilingual content arrive correctly encoded and attributed?
What breaks at the edges? Edge-case testing surfaces failures before production does.
Is sensitive data scoped correctly? Does cost hold at volume?
Side-by-side scoring against your current provider or an alternative. Apples to apples.
KeyKit is $250 a month, the same account for buyers and providers. Buyers evaluate any data or model API against their requirements. Providers get that same account, plus private self-testing and the ability to sponsor customers (see below).
$2,500/year
Evaluate any data or model API against your requirements.
A trial key hands the work to your prospect: find the time, wire it up, decide what the numbers mean. Most never get to it. Sponsor a KeyKit account instead and they get a neutral evaluation of your API against their own requirements, without the setup. If you're confident in your data, an independent verdict is the strongest thing you can put in front of them.
