log_decisionLog a signed decision event to the ledger. Managed Mode (default for MCP): omit signing fields and pass agent_name - Audifact securely manages an Ed25519 keypair and signs on behalf of the agent. Events are immutable once recorded; managed mode provides strong auditability after…
log_outcomeLog a signed outcome event linked to a prior decision via decision_event_hash. Managed Mode (default): omit signing fields - the managed key from the linked decision's agent is used automatically when the decision was also managed. For client-signed decisions, pass agent_private…
get_proofFetch the public proof payload for one ledger event by its 64-char hex event_hash. When to use: after log_decision/log_outcome when you need trust labels, chain validity, anchor status, or a paired-event proof URL. When NOT to use: to browse many decisions or outcomes — use list…

When to use: to review what an agent already logged, pick an event_hash for get_proof, or page through history before linking an outcome. When NOT to use: to list outcomes (use list…
list_agent_outcomesList outcome events for one agent (by public key) in the API key's org, newest first by default. When to use: to audit what results an agent recorded, find an outcome event_hash for get_proof, or page outcomes without already knowing hashes. When NOT to use: to list decisions (u…
