# Generic bounding-box query filtered by a single OSM tag

`GET /api/v1/environment/osm/bbox`

Return OpenStreetMap nodes, ways, and relations inside a bounding box that match a single tag filter (`tag_key=tag_value`). Bounding box area is capped at 1 square degree (~110 km x 110 km at the equator) to stay within Overpass resource budgets. The `tag_key` is restricted to a curated allowlist of top-level OSM keys; `tag_value` must match `[A-Za-z0-9_-]{1,64}`. Data is (C) OpenStreetMap contributors (ODbL 1.0) - attribution is required on any surface that renders this data.

## Query parameters

- `min_lat` number, required — South latitude of the bounding box (decimal degrees, WGS84).
- `min_lon` number, required — West longitude of the bounding box (decimal degrees, WGS84).
- `max_lat` number, required — North latitude of the bounding box (decimal degrees, WGS84).
- `max_lon` number, required — East longitude of the bounding box (decimal degrees, WGS84).
- `tag_key` string, required — OSM top-level tag key. Accepted values: amenity, boundary, building, craft, highway, historic, landuse, leisure, man_made, natural, office, power, public_transport, railway, shop, tourism, waterway.
- `tag_value` string, required — OSM tag value (1-64 chars, [A-Za-z0-9_-] only).
- `limit` integer — Maximum number of elements to return (1-2000).

## Response `200`

    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `401` — Missing or invalid `x-api-key` header.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
