Headers

X-Goog-FieldMask · string

Accepted for Google compatibility but ignored. The full response is always returned.

Body

application/json

Request body for route computation. Accepts all Google Routes API fields — unsupported fields are silently ignored.

origin · object · required

Origin waypoint (required)

Show child attributes

destination · object · required

Destination waypoint (required)

Show child attributes

intermediates · object[]

Intermediate waypoints (stops or pass-through points)

Show child attributes

travelMode · string · default: DRIVE

Travel mode. Only DRIVE is supported (truck routing).

routingPreference · string · default: TRAFFIC_UNAWARE

Routing preference. Traffic is not currently modeled.

departureTime · string<date-time>

Departure time in ISO 8601 UTC format. Affects school zone detection and time-based routing.

computeAlternativeRoutes · boolean · default: false

When true and no intermediate waypoints, returns up to 3 alternative routes.

routeModifiers · object

Route modifiers (avoid tolls, highways, ferries)

Show child attributes

languageCode · string · default: en-US

Language for navigation instructions

vehicleSpec · object

Vehicle specification for physics enrichment. Defaults to SEMI_TRAILER preset if omitted.

Show child attributes

routingProfile · enum<string> · default: balanced

Routing profile that adjusts enrichment weights

Available options: balanced, fuel_optimal, time_optimal, fatigue_aware

profileOverrides · object

Override individual profile weights (e.g. {"fuelWeight": 1.5})

Show child attributes

webhookUrl · string<uri>

Webhook URL for async route completion notifications. Only used by POST /v1/routes.

Response

200

application/json

Successfully computed route(s). The response matches the Google Routes API computeRoutes response shape exactly, with an additional enrichment field on each step.

Response from the Google-compatible computeRoutes endpoint. Returns one or more routes in the same format as the Google Routes API, enriched with segment-level physics data (grade, curvature, fuel burn, zone flags).

routes · object[] · required

Computed routes (primary + alternatives if requested)

Show child attributes

fallbackInfo · object | null

Google field — always null

geocodingResults · object | null

Google field — always null
