## Coverage
ISRO's Bhuvan geoportal, India's national satellite-imagery/geospatial platform. No documented keyless JSON REST API was found; the reachable public interface in this probe is OGC WMS (Web Map Service).

## Access
`GET https://bhuvan.nrsc.gov.in/` → **302**, zero-byte body, `Location: https://bhuvan.nrsc.gov.in/ngmaps` — the bare domain root always redirects to the map-viewer app, never serves content at `/` itself.

`GET https://bhuvan-vec1.nrsc.gov.in/bhuvan/wms?service=WMS&request=GetCapabilities` → **200**, `text/xml`, keyless, standard OGC `WMS_Capabilities version="1.3.0"` envelope — but the body is **10,128,547 bytes** (10.1 MB) in one uncompressed response, every one of Bhuvan's served layers enumerated in a single flat document with no paging, no layer-group filter, and no `Content-Length` on a `HEAD` request (the header set switches to chunked transfer; only `content-type: text/xml` and `x-content-type-options: nosniff` are present on `-I`).

A guessed REST path, `GET https://bhuvan-app1.nrsc.gov.in/api/`, → **200**, `text/html; charset=UTF-8`, 53,430 bytes — an ordinary HTML page, not a JSON API root; no indication this is a real documented endpoint rather than a generic app landing page.

## Auth
None for the WMS capabilities/map tiles reached; keyless.

## Rate limits
Not observed.

## Freshness
Not stated in-band.

## Known gaps
- A client that calls `GetCapabilities` expecting a quick service description instead receives a 10 MB+ download — the `--max-filesize 20000000` light-client ceiling used throughout this lane was deliberately set above this response for exactly this reason; a stricter 5–8 MB cap elsewhere would truncate this call.
- No JSON/REST catalogue API was located by GET; only the WMS/map-tile surface is confirmed reachable. Recorded as what was found, not as "Bhuvan has no API" — a documented REST layer may exist behind authentication not probed here.

How observed: 2026-10-05T09:16:10Z–09:16:39Z, curl 8.x, UA `pwx-scout/1.0`, direct HTTPS against `bhuvan.nrsc.gov.in`, `bhuvan-vec1.nrsc.gov.in`, `bhuvan-app1.nrsc.gov.in`.
