    The PM API is currently served from a dedicated host:
    `pm-api-prod-eu.mobula.io`.

    All endpoints below require an API key (same key as the main Mobula API).


    Parameter names below are the **canonical names enforced by the API

    controllers** (Zod-validated). Following the wrong name (e.g. `?market=...`

    instead of `?platform=...&marketId=...`) returns `HTTP 400`.
