agent_recordShow a Priors agent's full credit record on Robinhood Chain: name, owner address, who backs it (its sponsor/backer), its credit line, what is drawn and available, loans repaid and volume, score, open loans with due dates, and whether it has defaulted or is frozen. Use it before trusting, paying or lending to an agent. Read-only.score_ofLook up any agent's Priors score (0 to 1000) and repayment record on Robinhood Chain: a public record built from on-chain repayments. Shorter than agent_record. Useful before trusting or paying an agent. Read-only.credit_historyShow the loan history Priors posted for an agent on the ERC-8004 reputation registry (Robinhood Chain): loans repaid on time, repaid late and defaulted, and loans outstanding, from Priors' credit statements (the erc8004-credit/v1 profile). Each statement is read from its own transaction and checked here: its bytes and hash, the chain of statements, and a sample of its loans against the pools' logs. The totals are Priors' claims checked on that sample, up to the last statement (the answer gives its block and date; later loans are not checked here); the answer gives the command that rebuilds every loan. Read-only.
