# Data model: what you provide and what we compute

> How Nozle splits responsibilities — partners bring stations, prices, and vehicles; Nozle computes routing, distance enrichment, and optimization.

**Nozle is compute-only.** We don't maintain a station database
or pricing feed — partners bring their own station data, and we
do the routing math. Specifically:

* **You provide:** stations with current prices, a vehicle, and
  trip endpoints (or a precomputed route).
* **We provide:** route geometry, distance enrichment for your
  stations, the optimization algorithm, and a baseline comparison
  showing what naive refueling would cost.
  This separation matters because (a) you almost certainly have
  more accurate price data than any third-party feed could provide,
  and (b) it keeps the API stateless — no syncing, no staleness,
  no licensing constraints on station coverage.
