query
检索关键字。行政区划区域检索不支持多关键字检索。如果需要按POI分类进行检索，请将分类通过query参数进行设置，如query=美食是
location
圆形区域检索中心点，不支持多个点
38.76623,116.43213
lat<纬度>,lng<经度>		是
radius
圆形区域检索半径，单位为米。（增加区域内数据召回权重，如需严格限制召回数据在区域内，请搭配使用radius_limit参数），当半径过大，超过中心点所在城市边界时，会变为城市范围检索，检索范围为中心点所在城市否
output
输出格式为json或者xml否
多边形区域检索
开发者可使用多边形区域检索传入多个坐标对，首尾坐标对需相同，坐标对用”,”分割；多边形为矩形时，可传入左上右下两顶点坐标对。即可获取地点（POI）基础或详细地理信息。
