A risk number is only useful if you know how much to trust it. Alterscope answers that on every response, not in a separate report: each wrapped API response carries a small metadata block that states how fresh the underlying data is and whether it passed an automated quality check. Staleness and degradation are surfaced as data, never hidden.

Two questions, answered on every response

How fresh is this? Each response reports when the data was computed, how old it is, how often it refreshes, and a plain status: Is it fit to act on? Each response also carries a quality verdict derived from the platform’s confidence in the answer and whether any inputs were degraded: When a verdict is warn or fail, the response names exactly which fields were degraded, so there’s no guessing about what to trust.

Why this matters

  • No silent staleness. A number that’s an hour old looks identical to a fresh one unless the response tells you — so it does. This is the single most common failure mode in DeFi risk data, and it’s designed out here.
  • Auditable. The freshness timestamp and quality verdict are part of the response payload, so they can be logged and reviewed after the fact alongside the decision they informed.
  • Machine- and human-readable. Automated systems branch on the verdict; people read the same signal in plain language.

How staleness is detected, per source

Freshness is not one global timer — it is measured against the expected update cadence of whichever source backed the answer. That source is named on the response itself (meta._agentic.sources), so the freshness status is always tied to its origin. How each source is detected: The quality verdict then layers on top: it reflects the platform’s confidence and whether any input was degraded — so a response can be fresh but warn if one of its inputs was incomplete.

Where the data comes from

How the underlying data is sourced and normalized — connectors, archive node, time-series store, knowledge graph, and indexers — is covered in Data provenance.
