Map & Images

Get a map image for a whole day

GET
/map-image-daily/{date}/{width}x{height}.png

A PNG map image showing all of a day's hexagons, colored by what was reported. Only these sizes are accepted: 1200x600, 1000x500, 800x400, 600x300, 400x200, 400x250 and 300x150. A day with no data returns a plain default-view image.

Images are cached on the server for about 15 minutes, and repeat requests for a cached image do not count against the 20 per minute image limit (they still count toward the general 60 per minute limit). Rendering a new image is limited to 20 requests per minute per client. Responses are publicly cacheable.

Get a map image for one report GET

A PNG map image highlighting the hexagon of a single report, handy for link previews. Only these sizes are accepted: 1200x600, 1000x500, 800x400, 600x300, 400x200, 400x250 and 300x150. This endpoint is limited to **20 requests per minute**, because every request renders a fresh image. Please cache the result on your side. Successful responses are cacheable by browsers and CDNs for about a month. Returns `404` if the report does not exist or is not publicly available, and `400` for an unsupported size or a report without a map location.

List active webcams GET

Active webcams, ordered by name, with their latest captured image and the most recent report derived from each. A webcam with no capture yet has null image URLs.
