Trooth

Read one company's published record on the Trooth Network, given its domain or Trooth slug. The identifier is matched exactly (a URL is reduced to its host), never by a similar name. Returns a status (published, listed, private, unclaimed or unavailable) and a provenance label; text the company wrote about itself is labeled as its own words. Read only.

Fetch https://<domain>/ and /.well-known/security.txt once, when called, from Trooth's server and report whether HTTPS answered, which of five response headers (HSTS, CSP, nosniff, frame protection, referrer policy) are present, and whether security.txt is published, absent or unread. IP literals and names resolving to private, loopback or link-local addresses are refused; redirects are reported, not followed; each request stops after 4 seconds. Observations, not witnessed evidence, not a grade.

Answer a question about Trooth itself (what the Trooth Network is, what one company record carries, pricing, how witnessing works) from Trooth's fixed, curated knowledge base. Makes no outside request. A question the knowledge base does not cover returns out_of_scope; for a company's record use trooth_public_trust_profile.

Check the two signatures on a Trust Ledger Token (tlt2. or tlt. form, or its JTI) against Trooth's own token ledger. Returns valid, invalid (a signature does not check out), expired or revoked, or unclaimed when no token matches. Trooth's signature covers the signing event and the payload at issuance, not the truth of the claims the token carries.
