The API research lab for platform engineers who can't afford surprises. Rate limits documented. Deprecations tracked. Benchmarks you can ship on.
The numbers that
make the argument.
APIs Cataloged
Every endpoint documented — rate limits, auth schemes, versioning, deprecation timelines.
Avg Audit Turnaround
From API discovery to full benchmark report. Faster than most CI pipelines.
Accuracy vs Vendor Docs
Independent measurements vs vendor-reported specs. The gap is where incidents hide.
Breaking-Change Alerts Issued
Caught before official changelogs shipped. Your on-call rotation thanks us.
These numbers are a sample. The directory has 4,217 complete API profiles.

Monitor — Continuous Change Tracking
Deep Technical Audit
Deep Technical Audit
Every API gets a full inspection: authentication flows, rate limit behavior under load, error response consistency, SDK quality scores, and undocumented endpoints found via fuzzing. We read the changelog so you don't have to.
Multi-Region Benchmarking
Latency measured from 6 global PoPs, every 5 minutes, across P50/P95/P99 percentiles. Rate limits stress-tested. SLA accuracy scored against actual uptime data — not vendor-reported numbers.
Continuous Change Tracking
Deprecations, version bumps, breaking changes in response schemas — tracked before they hit the official changelog. We've issued 2,841 early-warning alerts. Median lead time: 11 days before vendor announcement.
38 categories.
Zero gaps in your stack.

"We were 45 minutes from shipping an integration when Endpoint flagged that Plaid had quietly changed their webhook payload schema 9 days prior. That alert saved our on-call rotation. We now run Endpoint before any third-party dependency decision."
"Writing comparison guides used to mean 3 days of manual testing. Now I pull the Endpoint benchmark report, verify the methodology, and have a credible data-backed draft in 4 hours. The accuracy percentile against vendor docs is the part that makes readers trust the analysis."
"The build-vs-buy question for our notification layer came down to Twilio, AWS SNS, and a vendor we hadn't heard of. Endpoint's governance scoring and rate-limit stress data gave us the exact numbers our board needed. We made the right call. We know because we measured."
