Understand APIs as they actually behave - not as they are documented.
Built from real-world research into how APIs behave in practice — not in documentation.
Cloud and SaaS platforms expose vast API surfaces.
Documentation tells you what should happen.
Reality is what your tenant is actually doing right now.
Those two things are rarely the same.
UndREST Labs is focused on closing that gap.
Observe → Understand → Map → Evolve
Real-time visibility into API calls as they happen.
- Inspect live traffic in your browser
- Compare against known API specs
- Identify undocumented or unexpected behaviour
Query and reason about API behaviour.
- Analyse patterns across API specifications
- Detect known anti-patterns across all documented API specs
- Turn raw API activity into insight - SpeQL is the engine that feeds APISpy
Mapping API ecosystems at scale.
- Continuous tenant analysis
- Behavioural baselining
- "Spec vs Reality" at enterprise scale
This is an active research and development space.
Initial releases are being prepared.
Expect rapid iteration and occasional chaos.

Assumptions have teeth.
Reality is the source of truth.
Capability ≠ intention.
This is research tooling intended for defensive security, analysis, and understanding complex API ecosystems.
Use responsibly.
