POST /v1/signal

unprobed

Financial evidence and pre-execution verification for autonomous agents across crypto, stocks, ETFs, macro and global financial markets. AIAPI independently retrieves relevant evidence, verifies caller-supplied claims and execution conditions, evaluates policy checks, reports missing or conflicting evidence, and returns structured decision and execution verdicts before capital moves.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
