Example evaluation. Results scored against your thresholds, not defaults.

The problem

Data procurement is still largely a leap of faith.

Vendor sales cycles are polished. Demo environments are cherry-picked. By the time you're live in production, you've already signed a contract.

KeyKit closes that gap. Run structured evaluation frameworks against a live trial key, scored against your actual requirements. Before the ink dries.

Review findings
01

Select your provider

Choose the API product you want to evaluate. KeyKit knows which frameworks apply to each provider type.

02

Paste your trial API key

KeyKit validates the key before anything runs. No wasted time on bad credentials.

03

Set your requirements

Define your actual thresholds: freshness tolerance, latency budget, field coverage %, reliability SLA, historical depth. Your requirements, not industry defaults.

04

Choose which frameworks to run

Pick from 30 ready-to-go frameworks across 10 groups. Dependencies are enforced automatically — you can't run Sort Order Stability before Result Set Stability.

05

Review fit-scored findings

Each framework scores FIT, PARTIAL FIT, or NO FIT against your scope. Live activity shows what's running. Findings include the measured value, the requirement, and a plain-language reason.

Evaluation frameworks

30 frameworks. 10 groups. Ready to run.

Every framework scores FIT, PARTIAL FIT, or NO FIT against your stated requirements, not industry averages. A provider that meets your thresholds gets credit. One that doesn't, doesn't.

Coverage

2 runs

Does the dataset cover the time range and regions your use case requires?

Historical DepthGeographic Coverage

Data Quality

4 runs

Are records complete, canonical, and free of duplicates before they hit your pipeline?

Determinism

4 runs

Does re-querying the same parameters return the same results? Critical for incremental pipelines.

Freshness

2 runs

How stale is "live" data? We measure actual ingestion lag against your stated tolerance.

Pricing

One platform. Two roles.

Buyers run evaluations to score API products against their requirements. Vendors sponsor prospects so buyers can evaluate them independently, against their own scope.

Start as Vendor
For data vendors

Let prospects evaluate you on their terms.

Buyers are getting more rigorous. Procurement teams are asking harder questions. A polished deck and a hand-picked demo no longer close deals on their own.

KeyKit's vendor tier lets you sponsor up to 20 prospects with full platform access. They run the evaluation frameworks themselves, against your live API, against their own scope. When findings score FIT, they know it. And so do you.
