Question 1

What is KeyKit?

Accepted Answer

KeyKit runs any data or model API through up to 30 structured tests against your own requirements and returns Fit, Partial Fit, or No Fit verdicts. It does the hard part of evaluating a data or model API, so you can see if it works for you without the scripts, engineer, and week that usually takes.

Question 2

How does KeyKit work?

Accepted Answer

You bring a trial API key for the provider you want to test. KeyKit runs structured evaluations against your stated requirements, freshness, latency, field fill rate, reliability, and more, with no provider involvement required, and returns a Fit, Partial Fit, or No Fit verdict for each test.

Question 3

What can I evaluate with KeyKit?

Any data or model API. KeyKit covers one-off evaluations, side-by-side provider comparison, ongoing health checks, and category benchmarks across coverage, data quality, freshness, reliability, and compliance.

Question 4

How much does KeyKit cost?

Accepted Answer

There are two plans. Pro is $199 per month or $1,990 per year, for buyers evaluating APIs. Provider is $749 per month or $7,490 per year, for providers proving and maintaining quality. There is no free tier.

Question 5

Who is KeyKit for?

Accepted Answer

Buyers use KeyKit to evaluate and monitor providers. Providers use it to prove quality to prospects with an evaluation the prospect runs themselves, so the results are not something the provider can influence.
