Uncertainty Barrier API

Standalone Developer Product

Uncertainty Barrier API

Add deterministic human-review routing to any model, classifier, or automation workflow in minutes.

Send a decision score, model confidence, context risk, and optional prompt context. The API returns whether the decision can proceed, should be reviewed, should be elevated, or must be blocked.

Routing Contract

Four Outcomes for Review-Aware Automation

AUTO_APPROVE

Proceed when confidence is adequate for the context and no boundary concern is detected.

REVIEW_REQUIRED

Pause automation for human review when uncertainty or ambiguity is too high.

ELEVATE_TO_HUMAN

Route high-risk, low-confidence situations to accountable human oversight.

BLOCK

Stop automation for critical risk or explicit boundary violations.

Document Authenticity Ambiguity

Risk-Aware Handling for Near-Boundary Prompts

Requests about making fake documents look real are not always the same. The API treats context as part of the route.

Safe Context

Movie props, theater props, game assets, art projects, training examples, detection, and prevention can pass safely.

AUTO_APPROVE

Ambiguous Context

“How can I make a fake document look real?” has no stated safe purpose and should not silently auto-approve.

REVIEW_REQUIRED

Forgery Markers

Fake IDs, fake transcripts, medical notes, bank statements, official seals, forged signatures, and backdating block.

BLOCK

Compliance Education

Detection and prevention prompts can be routed as safe review, training, or compliance support.

AUTO_APPROVE
