# Pirate Weather — keyless refusal fronted by Kong on CloudFront

`api.pirateweather.net` takes the API key as a URL **path segment**
(`/forecast/{key}/{lat},{lon}`), Dark-Sky-API-compatible. Behind a Kong gateway behind
CloudFront, and the refusal shape depends on whether the request matches that path
shape at all, not just on whether the key is valid.

## Probe 1 — well-formed path, fake key

```
curl -A "<contact-UA>" \
  "https://api.pirateweather.net/forecast/FAKEKEY123/40.7128,-74.0060"
```

Observed: `HTTP/2 401`, `www-authenticate: Key`, `server: kong/3.10.0.8-enterprise-edition`,
`x-cache: Error from cloudfront`, body:
```json
{"message":"Unauthorized","request_id":"5c3efb64ef1be829bf55b5028c255851"}
```

## Probe 2 — key segment omitted entirely

```
curl -A "<contact-UA>" "https://api.pirateweather.net/forecast/40.7128,-74.0060"
```

Observed: **`HTTP/2 404`**, not 401 — Kong's router has no route matching a 2-segment
`/forecast/{lat,lon}` path (it expects 3: `/forecast/{key}/{lat,lon}`), so this fails at
routing before auth is even evaluated:
```json
{"message":"no Route matched with those values","request_id":"5c500a7eedc5180d05e3e004fab82921"}
```
Both responses carry a fresh per-request `x-kong-request-id`/`request_id` and CloudFront
headers (`x-amz-cf-id`, `x-amz-cf-pop`); neither leaks anything about key validity beyond
"present but wrong" (401) vs. "shape of the URL itself is wrong" (404) — an agent that
drops the key segment to "test without auth" gets a routing error, not an auth error,
and must not read the 404 as "the service does not require a key."

## What the headers promise but don't show

Both the 401 and the 404 declare
`access-control-expose-headers: ratelimit-limit, ratelimit-remaining, ratelimit-reset` —
Kong tells the browser it is allowed to read those three rate-limit headers, but neither
refusal response actually **sends** them (no `ratelimit-remaining` header is present on
either probe). A client that checks for a rate-limit header to decide whether it is
being throttled vs. rejected for auth will find nothing to read on a 401/404, even
though CORS says it's permitted to look. Pirate Weather markets itself as a drop-in
Dark Sky API replacement (same path/response shape), which is why the key lives in the
path rather than a header or query param, unlike every other commercial weather API in
this cluster.
