# Check delivery zone coverage

> Checks whether a coordinate falls inside any active delivery zone of a connected location and returns the matching zone and delivery fee.

POST`https://api.maple.inc/v1/locations/{locationId}/delivery_zones/check`API key

Checks whether a coordinate falls inside any active delivery zone of a connected location and returns the matching zone and delivery fee. Requires `delivery_zones:read` and an active connection to the location.

## Authorization

Send your API key as `Authorization: Bearer <key>`: `mpk_test_…` against the sandbox (`https://api.staging.maple.inc/v1`), `mpk_live_…` against production. See [Authentication](https://docs.maple.inc/developer-api/concepts/authentication.md). The samples read the key from `MAPLE_KEY` and the base URL from `MAPLE_BASE`, as set up in the [Quickstart](https://docs.maple.inc/developer-api/quickstart.md).

## Parameters

- `locationId` string path required

## Request body

`application/json`, required.

- `latitude` number required

- `longitude` number required

## Responses

### 200 OK

- `object` string required

  Always `delivery_zone_check`.

- `in_zone` boolean required

- `zone` object or null required

- `zone.object` string required

  Always `delivery_zone`.

- `zone.id` string required

- `zone.location_id` string required

- `zone.name` string required

- `zone.zone_type` string required

  One of `polygon`, `circle`.

- `zone.polygon` object required

  A GeoJSON Polygon. Coordinates are `[longitude, latitude]` rings; the first ring must be closed.

- `zone.polygon.type` string required

  Always `Polygon`.

- `zone.polygon.coordinates` \[number, number]\[]\[] required

- `zone.radius_miles` number or null required

- `zone.delivery_fee_cents` number required

- `zone.min_order_cents` number or null required

- `zone.max_distance_miles` number or null required

- `zone.is_active` boolean required

- `zone.priority` number required

- `zone.created_at` string required

- `zone.updated_at` string required

- `delivery_fee_cents` number or null required

### Errors

- `400` Bad request DeveloperApiBadRequest

- `401` Unauthorized DeveloperApiUnauthorized

- `403` Forbidden DeveloperApiForbidden

- `404` Not found DeveloperApiNotFound

- `429` Too many requests DeveloperApiRateLimited

Every error body names the error in `_tag`, explains it in `message`, and says where to report it in `feedback`. See [Errors](https://docs.maple.inc/developer-api/concepts/errors.md).

A `429` also sends `Retry-After`: Seconds to wait before retrying; also returned as retry\_after in the body.
