# Infer Tracking Number (Beta)

> Predict the carrier SCAC and tracking number type from a bill of lading, booking, or container number using the Terminal49 Infer endpoint.

<Info>
  **Beta Feature** - This endpoint is currently in beta. The API is stable, but
  the schema and behavior may evolve based on feedback.
</Info>

## What this endpoint does

Provide a tracking number (container, bill of lading, or booking). The endpoint returns:

* The **predicted VOCC carrier SCAC** to use for tracking
* The **predicted number type**
* A confidence-driven **decision** (`auto_select`, `needs_confirmation`, `no_prediction`)

<Info>
  Terminal49 uses machine learning prediction across container, bill of lading,
  and booking numbers. For container numbers, Terminal49 leverages tens of
  millions of historical container movements to predict which carrier is moving
  the container (about 9 out of 10 times).

## How to use the result

<Warning>
  This endpoint has its own rate-limit bucket: 200 requests per minute per API key.
