get_claim_ledgerread-onlyGet the claim ledger for one essay: each load-bearing claim it makes, the source it was checked against, the quoted words, where in the source they appear, the date the source was read, and a status saying how the claim was checked. The response defines every status. Claims removed during checking are listed separately under "struck", with the reason; they are not claims the essay makes. Only some essays have a ledger: search results and get_essay link to one when it exists. These tools retrieve The Durability Curve's public material. They do not certify that any claim is true.
