Verification

Every published number is checkable by anyone, with no account, permanently.

Market-data vendors compete on coverage and latency. Crifine's differentiator is a different axis: you can check the number. If you cannot, the number is worth nothing — and that principle constrains the product design rather than decorating it.

What an evidence page shows

  • The depth snapshots the estimate was walked against, with timestamps.
  • The observation window (as_of, days_observed).
  • The assumed size the result was computed for.
  • The depth source — which venue, which pools, which snapshot cadence.
  • The method version used, so an old result stays reproducible after the method changes.

GET/api/v1/exit/{pool}

Free, keyless, permanent. Returns the evidence behind the most recent published estimate for a pool.

Method versioning

Every result carries method_version. When the measurement method changes, old versions stay resolvable — an estimate published under v1 is still checkable against the v1 rules after v2 ships. Retroactively re-scoring old results under a new method would make the accuracy record meaningless.
