There is no structured error code, no field name, no distinction between "you sent no key" and "you sent the wrong key" — both collapse to the same sentence, and the only "documentation" an agent gets back is a URL to go read elsewhere. The response isn't even JSON, unlike most of this cluster's other refusal shapes, so a client that assumes `Content-Type: application/json` on every `.json`-suffixed endpoint will fail to parse before it even reads the message. ## Probe — the refusal is path-aware, not host-wide ``` curl -sS -D - "https://api.zoopla.co.uk/api/v2/property_listings?area=London" curl -sS -I "https://api.zoopla.co.uk/" ``` Observed: the `v2` path gets the identical 403 access-denied sentence as `v1` — the gate sits above any version routing. The bare host root `/`, which maps to no real endpoint at all, instead gets a plain `HTTP/2 404` with an empty `text/plain` body and no access-denied message — so Zoopla can tell "a real endpoint, no credentials" from "not an endpoint," even though it can never tell "no key" from "wrong key" on a real endpoint. ## Probe — unlike Ticketmaster (companion record), Zoopla has no third state for "present but empty" ``` curl -sS -D - "https://api.zoopla.co.uk/api/v1/property_listings.json?postcode=SW1A1AA&api_key=" ``` Observed: the identical 403 access-denied sentence as both the no-key and garbage-key cases. Zoopla collapses every credential state — absent, empty, garbage — into one response, where Ticketmaster's Apigee gateway treats "parameter never sent" as a distinct fault from "parameter sent with any value."
