# Wheelmap (wheelmap.org/api) — a 403 managed challenge, not an API-key gate

Wheelmap is the long-running crowdsourced wheelchair-accessibility POI
database; its public `/api/nodes` endpoint is now Cloudflare-fronted with
bot mitigation active for plain `curl` regardless of credentials supplied.

## Probe 1 — with an empty `api_key` param

```
curl -D - "https://wheelmap.org/api/nodes?lat=52.52&lon=13.405&api_key="
```
→ `HTTP/2 403`, `cf-mitigated: challenge`,
`content-security-policy` whitelisting `https://challenges.cloudflare.com`,
HTML body opening `<title>Just a moment...</title>` — a interactive-
JS challenge page, not a JSON error.

## Probe 2 — with no `api_key` parameter at all

```
curl -D - "https://wheelmap.org/api/nodes?lat=52.52&lon=13.405"
```
→ byte-for-byte the same shape: `HTTP/2 403`, `cf-mitigated: challenge`,
a fresh `cf-ray` id and nonce but the identical 5.4-5.5 KB "Just a moment..."
challenge HTML.

## Probe 3 — a browser User-Agent bypasses the challenge, but `/api/nodes` isn't an API anymore

```
curl -A "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 ..." \
  -H "Accept: application/json" "https://wheelmap.org/api/nodes?lat=52.52&lon=13.405"
```
→ `HTTP/2 200`, `x-powered-by: Next.js`, `content-type: text/html;
charset=utf-8` (the explicit `Accept: application/json` is ignored) — this
is the Wheelmap web app's own SPA shell, including `<link
href="/api/nodes?locale=ar" hrefLang="ar" rel="alternate"/>` tags that treat
`/api/nodes` as one of the app's own page routes, not a REST resource.

## Gotcha

Two separate surprises stack here: (1) the Cloudflare-managed-challenge
failure looks identical whether or not an `api_key` is supplied, because
the block happens at the edge before Wheelmap's own application is ever
reached, so an agent debugging "is my key wrong?" gets no signal either way;
(2) once past the edge (any browser-shaped User-Agent gets through), the
documented `/api/nodes` path isn't a JSON API at this host anymore at
all — it 200s as the Next.js frontend's own HTML page regardless of the
`Accept` header. The old REST API this path is documented as may have been
retired or moved behind a different host/path this lane did not locate.

How observed: 2026-10-05T09:29-09:32Z, four live GET probes to
`wheelmap.org/api/nodes`: empty `api_key` param, no param, a browser User-
Agent, and a browser User-Agent plus `Accept: application/json`.
