Sources

Every fact is auditable to where it came from.

Every fact carries provenance. Nothing is asserted without a source, and each answer traces back to the page it came from, when it was fetched, and how strongly the source supports it.

#What a fact carries

Every current fact, as returned by a profile, carries:

FieldMeaning
valueThe typed value (bool, string, list, or object)
confidence0 to 1, how strongly the source supports the fact
observedAtWhen it was fetched
staleWhether it is past its freshness TTL

Behind each fact is a source record with the exact URL it came from, the time it was fetched, and how strongly that source supports the value.

#Confidence

Confidence reflects how the fact was established, not a vote.

  • Deterministic signals are high confidence. A published npm package, a *-mcp GitHub repo, or a served llms.txt file set their facts at 0.9 and above, because the evidence is hard. See Methodology.
  • Vendor-verified facts are high confidence, after a domain claim.
  • A single-source model extraction is medium.
  • An inferred value is lower.

#Citations you can check

research_company returns its sources array directly, so you can open or cite the exact URLs behind the answer. The answer is grounded strictly in those sources: if a source does not support a claim, the claim is not made.

  • Freshness: the stale flag and TTLs.
  • Schemas: the fields each source populates.
