# ChargePrice API: route-exists-vs-key-missing is distinguishable

ChargePrice (price comparison for EV charging tariffs) runs its API on
Heroku and answers with a clean JSON:API error envelope that distinguishes
"this route exists but you lack a key" from "this route doesn't exist."

## Probe 1 — a route that doesn't exist

```
curl -s -D - "https://api.chargeprice.app/v1/stations"
```

Observed:

```
HTTP/2 404
content-type: application/json
server: Heroku

{"errors":[{"status":"404","code":"NOT_FOUND","title":"Errors::NotFound"}]}
```

## Probe 2 — a real, documented route with no key

```
curl -s "https://api.chargeprice.app/v1/vehicles"
```

Observed:

```
{"errors":[{"status":"403","code":"FORBIDDEN","title":"api_key missing"}]}
```

`/v1/tariffs` gives the identical 403 shape; `/v1/providers` and
`/v1/stations/1` give the 404 shape above — so the 403-vs-404 split tracks
real-route-vs-not, consistently.

## Probe 3 — spoofing an Origin header does not help

```
curl -s -D - "https://api.chargeprice.app/v1/vehicles" -H "Origin: https://chargeprice.app"
```

Observed: the same 403 `api_key missing` body — the web app's own origin is
not treated as an implicit credential, confirming the key check is
server-side, not a CORS-only gate.

## Takeaway

ChargePrice's error envelope is one of the cleaner refusal shapes in this
cluster: JSON (not plain text or empty body), a stable `code` field an agent
can branch on, and a real 403/404 split that tells you whether the endpoint
path itself was even right.

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.
