Sources

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:

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.
