SQL query to test locally. Same in API with some attributes removed. You can change the lat/long for other locations. Here i picked le Pâquier

SELECT "id",ST_force2d(location), "title",
ST_X(ST_SnapToGrid(location, 0.0001)) AS "longitude",
ST_Y(ST_SnapToGrid(location, 0.0001)) AS "latitude"
FROM "images" AS "images"
WHERE ("images"."state" = 'validated' 
AND ST_Contains("images"."footprint", ST_SetSRID(ST_MakePoint(7.053254941554428, 46.594400727633314), 4326)) = true
AND ST_Distance(ST_SetSRID(ST_MakePoint(7.053254941554428, 46.594400727633314), 4326)::geography,
    "images"."location"::geography) <= 2000);
