### Query parameters

- `only_latest` (boolean, optional, default: true) — If true, only the latest known engine status per vehicle is returned.
- `fleet_ids` (list of string, optional, nullable) — Limit results to specific fleets using Catena's fleet IDs. *For your own fleet identifiers, use `fleet_refs` instead* To specify multiple values, repeat the parameter for each value (e.g., `?fleet_ids=id1&fleet_ids=id2`).
- `fleet_refs` (list of string, optional, nullable) — Limit results to specific fleets using your organization's fleet reference identifiers. To specify multiple values, repeat the parameter for each value (e.g., `?fleet_refs=ref1&fleet_refs=ref2`).
- `connection_id` (string, optional, nullable) — Limit results to a specific provider connection. This is the UUID assigned by Catena when your fleet connects to a TSP.
- `from_datetime` (datetime, optional) — Return only records that occurred on or after this date and time. **Format:** ISO 8601 (UTC) **Applies filter:** `occurred_at >= from_datetime` **Default value:** `now() - 1 day` **Restriction:** `to_datetime - from_datetime` cannot exceed 45 days
- `to_datetime` (datetime, optional) — Return only records that occurred before this date and time. **Format:** ISO 8601 (UTC) **Applies filter:** `occurred_at < to_datetime` **Default value:** `now()` **Restriction:** `to_datetime - from_datetime` cannot exceed 45 days
- `driver_ids` (list of string, optional, nullable) — Limit results to specific drivers. **Maximum:** 100 IDs To specify multiple values, repeat the parameter for each value (e.g., `?driver_ids=id1&driver_ids=id2`).
- `vehicle_ids` (list of string, optional, nullable) — Limit results to specific vehicles. **Maximum:** 100 IDs To specify multiple values, repeat the parameter for each value (e.g., `?vehicle_ids=id1&vehicle_ids=id2`).

## Types

### EngineStatusRead

Engine status API model with fleet fields.

- `fleet_id` (string, required, nullable) — Internal fleet identifier.
- `id` (string, required) — Unique identifier of the record at Catena Telematics.
- `created_at` (datetime, required) — Immutable: The datetime the record was ingested into Catena Telematics.
- `updated_at` (datetime, required) — The dateime the record was last modified in Catena Telematics.
- `connection_id` (string, required) — Unique identifier of the connection at Catena Telematics through which this record was ingested. A connection represents a Fleet/TSP pairing.
- `source_name` (enum, required) — The underlying telematics platform that provided this data (e.g., `samsara`, `motive`, `hos247`). Note: Some platforms like `hos247` offer white-labeling, so multiple TSPs may share the same source_name — use `tsp_id` or `tsp_slug` to identify the specific ELD provider.
  - Allowed values: `ada`, `ai_eld`, `air_eld`, `alfa_eld`, `alpha_eld`, `als`, `anytrek_pro`, `anytrek_classic`, `apex_eld`, `apollo`, `apollocloud`, `ascend`, `att`, `awaregps`, `azuga`, `bigroad`, `bluehorse_eld`, `blueinktech`, `bouncie`, `budgetgps`, `catena_simulator`, `captain_eld`, `carrier_lynx`, `chronos`, `club_eld`, `cogo_eld`, `counting_trucks_eld`, `cyntrx`, `digital_eld`, `dragon_eld`, `dreyev`, `drive_hos`, `drive_hos_v2`, `driver_tech`, `dsg_elogs`, `dynamic_eld`, `eighteighteight_eld`, `eld_88`, `eld_books`, `eld_mandate`, `eld_mandate_prime`, `eroad`, `eva_eld`, `evo_eld`, `expressway_eld`, `extreme_eld`, `ezlogz`, `ez_lynk`, `factor_eld`, `firstgate`, `fleetcomplete`, `fleetcompletehub`, `fleethunt`, `fleetpulse`, `fleetsharp`, `fleetup`, `fm`, `fordpro`, `forwardthinking`, `forza_eld`, `geotab`, `gpsinsight`, `gpstab`, `gpstrackit`, `grand_eld`, `greenlight`, `groundhog`, `hcss`, `hos247`, `hutch`, `intellishift`, `ironman_eld`, `isaac`, `jjkeller`, `kinexaiot`, `knight_eld`, `konexial`, `lioneight`, `linxup`, `loop_eld`, `lucid_eld`, `luna_eld`, `lytx`, `lytxv3`, `mapon`, `matrack`, `maven`, `mdm_eld`, `michelin_connected_fleet`, `mobilefleet`, `moonlight_eld`, `motion_eld`, `motive`, `my_drivebook`, `my_logs_eld`, `nero`, `netradyne`, `new_eld_world`, `nextgen_eld`, `nextraq`, `nexus_eld`, `omnitracs`, `1sew_eld`, `onestep`, `ontime_eld`, `optima`, `optimus_tracker`, `orbcomm`, `orient_eld`, `ozod_eld`, `panda_eld`, `patriot_eld`, `payd`, `peak_eld`, `pedigree`, `peoplenet`, `phillips_connect`, `phoenix`, `pop_eld`, `prologs`, `proride_eld`, `qualitylogs_eld`, `randmcnally`, `rastrac`, `raven`, `redfox`, `regulog_eld`, `ridehub`, `rigbot`, `roadeazy`, `roadready`, `rock_eld`, `rollingtrans`, `routemate`, `route_one_eld`, `royal_eld`, `safelane`, `samsara`, `selectivedrive`, `simba_eld`, `skybitz`, `smart_elds`, `sparkle_eld`, `spireon`, `sts_eld`, `sun_eld`, `surfsight`, `swift`, `switchboard`, `synergy_eld`, `teletracnavman`, `teletracnavman_director`, `telogis`, `tenna`, `teslemetry`, `thermo_king`, `think`, `tive`, `topcompliance_eld`, `traccar`, `trackease_eld`, `trackpro`, `traclog`, `transflo`, `trimac`, `trimble`, `truckford`, `truckspy`, `truckx`, `trueroad_eld`, `tt`, `txt_eld`, `us_fast_eld`, `verizon_connect`, `vista_eld`, `vistracks`, `vlog_eld`, `vulcansols_eld`, `wialon`, `webfleet`, `wizefleet_eld`, `xplore_eld`, `zigzag_eld`, `zms_eld`, `zonar`, `zubie`
