}A
For comparison, a thinly-covered domain:
A signal is “missing” if it’s currently scoring at the neutral fallback (≈ 50 / 100). This is not the same as a zero — neutral 50 means “we have no real data, so we’re not penalizing or rewarding.” A long missing list pulls the composite toward 50.
composite_score of 67 sounds the same whether it was computed on full data or half-empty fetcher results. This endpoint exposes the difference: data completeness, failed fetchers, and which signals fell back to neutral defaults.
When to use it
- Before trusting a score for a high-stakes decision.
- To render a “confidence” pill next to the score in your UI.
- To explain to a stakeholder why a small / private company has a directional rather than precise score.
The three bands
| Band | Meaning |
|---|---|
high | Completeness ≥80% and no critical fetcher failures. Trust the number. |
medium | 60–79% completeness, or one non-critical fetcher missing. Use as a directional indicator; cross-check critical buckets. |
directional | <60% completeness or a critical data fetcher failed. Treat the composite as a rough position, not a precise reading. |

missing_signals semantics
A signal is “missing” if it’s currently scoring at the neutral fallback (≈ 50 / 100). This is not the same as a zero — neutral 50 means “we have no real data, so we’re not penalizing or rewarding.” A long missing list pulls the composite toward 50.
How completeness is computed
A weighted ratio of “signals with real underlying data” / “signals applicable to the target’s profile”. Established companies have different applicable signals than growth companies (some venture-stage signals are N/A for mature firms), so the denominator is profile-aware.Authorizations
