Choose from authority-defined tools. Every detail page shows all interface bindings, parameter descriptions, required scopes, allowed purposes, the return contract, lifecycle state, producer capabilities, safe alternatives, and a credential-free request example.
Return structured fact changes between filings, snapshots, or known-at points.
Argus itself does not generate investment judgments or execute orders. Client AI agents may use lawfully accessible facts and labeled source material for independent reasoning and output.
