real-time scoring

One API key. Pay per call, free to start. Every response ships a tamper-proof signed receipt you can verify with /v1/verify.

How the API flows

Seven stages. One signed response.

Every public endpoint runs the same seven-stage loop server-side and returns a verdict, a risk score and a verifiable certificate id.

Step 01

Suggested

A POST hits /brain/query with a decision

Step 02

Reviewed

Engines run, for / against compiled

Step 03

Approved

API returns verdict + risk + cert id

Step 04

Executed

Your app executes the decision downstream

Step 05

Measured

You PATCH outcome back to /decisions/:id

Step 06

Learned

Webhook delivered · models recalibrate

Step 07

Closed & fed back in

usage.recorded · loop closed for the call

The loop closes — every outcome feeds the next decision
