What is this?

Enterprise AI APIs add SLA tiers, audit logging, schema validation, and backward-compatible versioning.

Why should you care?

AIPredict enterprise merchants require audit trails and 99.9% uptime on fraud scoring.

See it live — copy this example

Use a .NET console or Web API project with Microsoft.ML. Run dotnet run after pasting.

app.MapPost("/api/v1/fraud/score", async (TxRow tx, PredictionEnginePool<TxRow, FraudPred> pool, IAudit audit, HttpContext ctx) =>
{
    var p = pool.Predict(tx);
    await audit.LogAsync(ctx.User.Identity!.Name!, tx, p, modelVersion: "v12");
    return Results.Ok(new ApiEnvelope<FraudPred>(p, requestId: ctx.TraceIdentifier));
});

What happened?

  • Envelope responses include requestId for support.
  • Audit stores who scored what for compliance.

Practice next

  1. ApiEnvelope wrapper.
  2. Audit each predict.
  3. TraceIdentifier in response.
  4. SLA tier header routing.
  5. Deprecate v1 with sunset header.

Remember

Audit trail. Stable envelopes. Versioned routes.

AIPredict enterprise SLA

Bank audits fraud scores for Q2.

Outcome: RequestId traces every prediction row.
