# Per-category travel times at many points

`POST /v1/point/summary`

## Request

- Base URL: `https://api.close.city`
- URL: `https://api.close.city/v1/point/summary`
- Auth: HTTP bearer

Fastest travel time to each destination category by mode, from the census
block containing each of many lat/lon points. This is the batch form of
`GET /v1/point/summary`, a POST on the same path. Each row carries its
`origin_lat` and `origin_lon`, and `origins` maps each point to its resolved
block with population and land area.

## Request body

- PointSummaryBatch
  - `mode` string[], nullable
  - `origins` PointOrigin[], required: Origin lat/lon points (1-250)
    - `lat` number, required
    - `lon` number, required
  - `type` integer[], nullable

## Response `200`

    - `origin_lon` number, required
    - `travel_time` number, required: Minutes, capped at 30, 1 decimal
  - `truncated` PointOriginKey[], required
    - `origin_lat` number, required
    - `origin_lon` number, required
  - `truncated_reason` string, nullable: 'insufficient-balance' or 'row-budget'; null if nothing was truncated
