AI Execution Control Layer

Reliable AI Execution. Controlled Execution.

SIGTREX API is the execution control layer for AI — preventing drift, blocking unsafe multi-step prompts, reducing wasted spend, and producing replayable proof for every execution your agents make.

Why Teams Trust SIGTREX

Every AI execution is controlled, verified, and auditable

Drift prevention

Pre-execution checks flag scope creep, hallucination patterns, and unsafe step expansion before the model spends a token.

Cost protection

Hard caps on input + output cost per run. Runaway prompts get blocked and reported with exact dollars saved — auditable, defensible.

Replayable proof

Every decision logged with full trace, drift score, and reason — replay any execution by ID at any time.

Output control

Strict mode enforces evidence, output bounds, and fail-safe policy so downstream systems never receive unsafe output.

Built for teams that can't afford AI mistakes

Block unsafe multi-step prompt explosions before spend happens.

PA
Prevent runaway agents

Track prevented spend, token savings, and execution waste.

RC
Reduce AI costs

Full trace, drift explanation, and replayable proof for every run.
