4P Engine · AI logic verification and deterministic intelligence

4P Engine — Logic-first AI verification

Validate claims, proofs, and machine-generated answers through a deterministic architecture grounded in Logic, provenance, coherence, and explicit evidence boundaries.

API INTEGRATION

External services send data TO 4P via this endpoint:

POST /api/proof/check

How it works:

1. Your service calls the endpoint above with your API key

2. 4P validates the input through the Output Gate

3. Results POST to your webhook URL (if configured)

Headers: X-API-Key: your_keyBody: { "input": "your text", "context": "universal" }

Verify claims through Logic, evidence, and provenance

4P Engine separates authored premises, formal derivation, empirical evidence, machine interpretation, and unresolved scope so each result can be inspected rather than merely trusted.

Use the public research, documentation, Canon, and OASIS surfaces to examine the system's proofs, operating boundaries, and deterministic validation methods.
