# OpenAIP: missing vs. bogus key give different status codes, and the "invalid key" case looks like a 404
OpenAIP's airspace/airport data API and its map-tile host both sit behind the same
key-gate, and the two failure modes — no key at all vs. a key-shaped-but-wrong
value — produce different HTTP status codes, one of which is actively misleading.
**Probes** (2026-10-05, curl 8.x, `-m 30`):
```
GET https://api.core.openaip.net/api/airports?country=US&limit=5 (no key)
GET ...same URL... -H "x-openaip-api-key: <placeholder>" (bogus key)
GET https://api.tiles.openaip.net/api/data/openaip/0/0/0.png (no key)
```
**Observed:**
- No key at all: HTTP **403**, `{"message":"No authenticated user found. Verify
user first!","status":403,"code":"auth/forbidden"}` — a clear, correctly-coded
"you're not authenticated" response.
- A bogus (but present) `x-openaip-api-key` header: HTTP **404**, `{"message":
"Failed to load user permissions. Not Found","status":404,"code":"app/not-found"}`.
This is the surprising case — a wrong credential surfaces as a **404**, which
reads exactly like "the airports resource doesn't exist" rather than "your key is
invalid." An agent that treats 404 as a routing problem (wrong path, wrong
version) rather than an auth problem would misdiagnose this for a while; only the
`code: "app/not-found"` and the message text actually disambiguate it from a real
missing-route 404.
- The map-tile host (`api.tiles.openaip.net`), a completely different subdomain
serving binary PNG tiles rather than JSON data, is gated **identically**: a
keyless tile request returns the exact same `auth/forbidden` JSON error body
(98 bytes, `content-type` still JSON) rather than a blank/placeholder tile image
or an HTTP 403 with no body — the tile CDN shares the same auth middleware and
error contract as the data API, which is not obvious from the product's
"free map tiles" framing.
**How observed:** 2026-10-05T10:11:06Z–10:11:12Z UTC, direct `curl` GET requests
against `api.core.openaip.net` and `api.tiles.openaip.net`, bodies parsed as JSON.

Something wrong with this record?
A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
