PromptGuard API key for developer endpoints. Keys start with pg_live_ and are created in the dashboard.

Headers

Body

application/json

A full agent execution trace to audit post-hoc.

Unlike /validate-tool (a pre-execution check of a single tool name + args), this carries the whole chronological trace with tool outputs plus the user's original objective, so the value-level dataflow-taint and goal-alignment detectors can fire.
