Pick the right AI API relay, stop overpaying

API Compass tracks and independently measures relay and aggregator services worldwide, publishing each one's uptime, response latency, model coverage and backend engine — with the service's own advertised rates and minimums listed separately. We do not sell, resell or proxy anything; we just lay the data out.

How to read the data: uptime, response latency, model counts and endpoint verification are all measured by our own daily probes. Uptime is judged per day (over a 30-day window it answers "how many days was it down out of 30"), which is why values cluster at 96.7% and 93.3% — read the stability band to tell services apart. Rates, minimums and promotions are published by the services themselves on public channels; we log them and cite the source but they are not our measurements — always confirm on the service's own billing page. Last data verification: 2026-10-22.

What this site is for

The biggest problem in this market is information asymmetry: every landing page claims to be stable and cheap, but real uptime, actual response speed, whether a given model is genuinely available, and how a quoted rate is calculated are all impossible to check before paying. And mistakes are expensive — prepay for credit, the service disappears or quietly downgrades its models, and the money is gone.

So we do three things:

  • Publish measured data. We probe reachability, endpoint authenticity and response time daily, and rank by uptime and real latency rather than by who paid the most.
  • Keep advertised and measured figures apart. Rates and minimums — which the services state about themselves — go in their own table with the source cited, never mixed into the measured metrics, so advertising is never mistaken for performance.
  • Give official prices a baseline. We maintain a price list from each vendor's own pricing page, so you can check whether a "0.3x rate" is actually a good deal.

We do not proxy, resell or top up APIs, take no part in any transaction, and do not vouch for any service's finances. See About for how listing and ranking work.
