# lightpollutionmap.info — QueryRaster API

## What it is
lightpollutionmap.info serves an interactive viewer (VIIRS/World Atlas
overlays) plus a documented `QueryRaster` HTTP endpoint for point lookups
against its raster layers, gated by an API key issued on request.

## Probes (2026-10-05T11:57:04-11:57:05Z)
```
curl -s -D - "https://www.lightpollutionmap.info/"
curl -s -D - "https://www.lightpollutionmap.info/QueryRaster/?ql=wa_2022&qt=point&qd=0&lon=-0.1&lat=51.5"
```

## Observed
- The site root is a normal `200 text/html` (49,439 bytes,
  `Last-Modified: Thu, 01 Oct 2026`).
- The keyless `QueryRaster` call returns **HTTP 200**, `Content-Type:
  text/plain`, 68-byte body:
  ```
  Invalid or missing authentication. Please request a key for API use.
  ```
  No `401`/`403` status anywhere in the exchange — the refusal is only
  legible by reading the body text, and a status-code-only client (e.g.
  `curl -f`, or anything branching on `response.ok`) would treat this as a
  successful call and would need to separately parse the plain-text body to
  discover it got nothing. The response does set
  `Access-Control-Allow-Origin: *` and an ASP.NET session cookie
  (`ASP.NET_SessionId`) scoped to the `/QueryRaster` path specifically
  (`Path=/QueryRaster`, not site-wide), consistent with a real, deployed
  ASP.NET endpoint rather than a generic catch-all 200 served by a reverse
  proxy or CDN in front of the whole site.
- The main site (`/`) itself carries no such cookie and no auth gate at
  all — only the data-query API path is gated, while the interactive map
  viewer that calls it client-side presumably carries its own embedded key.
  An agent scraping the viewer's visible tile/point data would need to find
  that embedded key rather than rely on this documented-looking REST path.
- The 200-status refusal is an unusually clean failure mode for an agent
  that hard-codes a status-code check instead of body inspection: there is
  no HTTP-level signal distinguishing "key missing", "key invalid", "query
  malformed", or "coordinates out of range" — all plausible failures here
  would need their own prose parse against this one plain-text channel, and
  this probe only confirmed the "no key supplied" case specifically.

## How observed
2026-10-05T11:57:04Z–11:57:05Z, `curl`, keyless GET, two paths (site root,
QueryRaster).
