# Use Cases

TaτsuOS is application-agnostic, but the following are representative of the deployments planned for the first twelve months.

**Industrial sensor networks.** A factory deploys TaτsuOS-enabled vibration sensors. On the Starter tier, devices stream basic 1 Hz telemetry. Upgrading to Builder or Pro unlocks high-rate sampling, OTA firmware pushes, and fleet-wide dashboards — all gated by the monthly TATSU subscription burn rather than a fiat contract with a single vendor.

**Agricultural telemetry.** A farm cooperative deploys soil-moisture probes. Each member pays once, in TATSU, to unlock the cellular-uplink feature on the probes assigned to their plot.

**Consumer prosumer hardware.** A camera ships with on-device object detection disabled. The buyer subscribes to the Pro tier, which includes access to the AI model layer, and the capability is unlocked via a cryptographic receipt — no separate vendor account, no opaque fiat billing.

**Aftermarket vehicle modules.** A retrofit telemetry module ships with basic OBD-II reporting. Advanced features — fleet-grade location reporting, driver-scoring inference — are on-chain unlocks.

**Research and educational deployments.** A university lab buys 200 boards for a course. Unlock features per student, per semester, with a clean cryptographic record of who paid for what.

In each case, the OEM ships one SKU, the buyer pays once, and the entitlement is portable — bound to the device, not to the buyer's account with the vendor.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://tatsu.gitbook.io/tatsu-whitepaper/use-cases.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
