STATIC MAP API

The request describes the map. The response is the map.

One GET, one image. No map SDK in the browser, no tile orchestration, no headless Chrome on your server.

GET /map.svg?scope=world&data=US:200,CN:150,DE:95&theme=dark

World choropleth rendered from a single GET request

If the end result is an image, ship an image

No client runtime

Nothing to initialise, nothing to bundle, no token in the browser. An image tag is the whole integration.

No headless browser

Maps are rendered from strings with d3-geo and resvg. No Puppeteer, no screenshot pipeline, no GPU.

No tile server

Nothing to host, cache or pay per tile for. The boundaries ship inside the service, and one request returns the finished map.

SVG or PNG from the same definition

SVG for websites, reports and print — sharp at any size, small over the wire, selectable in a PDF.

PNG for email, Slack and social cards, where SVG is not rendered. Ask for any width up to 8,000 px.

GET /map.png?scope=world&data=US:200,CN:150&width=1600

SVG and PNG output

Responses are cached hard: an ETag plus immutable cache headers, with Cloudflare in front. The same URL is the same bytes.

CORS is open, so the image works from any origin.

POST /render/map takes a JSON or CSV body when the dataset is too big for a query string.

Built for data, not for street tiles

Choropleths by country or by ISO 3166-2 subdivision, across 177 countries and 16 group scopes.

Region highlights without values, categorical fills, per-region colour overrides and five pattern fills.

Markers with 30 icons, NATO APP-6 symbols, proportional circles, great-circle and sea routes.

North arrow, scale bar, graticule, region labels, five projections, six themes, and a bbox crop for any viewport.

Sea routes from Shanghai, Tokyo and Singapore drawn through real shipping lanes

Add sea to a route and it follows the Eurostat marnet shipping network instead of cutting a great circle over land. Endpoints snap to the nearest lane.

Embed it like any other image

<img
  src="https://api.maproll.io/map.svg?scope=world&data=US:200,CN:150,DE:95"
  alt="World data map"
/>

p: That works in a website, a README, generated documentation, a dashboard, a PDF pipeline, a CMS — anywhere that already knows how to show an image. Use an image tag rather than an iframe: no second browsing context, no scrollbars.
