# Domain.com.au API (`api.domain.com.au` / `auth.domain.com.au`) — Envoy gateway + Akamai bot defense

```
curl -sS -D - "https://api.domain.com.au/v1/listings/residential/_search"
```
Observed: `HTTP/2 404`, `server: envoy`, `x-notfound: True`,
`{"title":"Not Found","detail":"No Matching Route"}` — a GET to the documented search
path isn't a method-not-allowed or an auth wall, it's a routing miss: Domain's search
is POST-only at the gateway level, and GET doesn't even reach an auth check (consistent
with rule 14 — no POST was sent to find out what GET can't show).

## Probe — the OAuth token endpoint, reached live behind Akamai

```
curl -sS -D - "https://auth.domain.com.au/v1/connect/token"
```
Observed: `HTTP/2 400`, `server: envoy`, `x-robots-tag: noindex, nofollow`,
`{"error":"invalid_request"}` — a textbook OAuth2 `invalid_request` for a token call
with no `grant_type`/body, reached despite three Akamai bot-defense cookies being set
on the same response (`_abck`, `ak_bmsc`, `bm_sz`) — the bot-defense layer here
fingerprints and tags the client but does not block a bare GET outright, unlike
Realtor.com's Kasada wall, which returns 429 before any application logic runs at all.

## Probe — a GET-supported resource route, for contrast with the POST-only search path

```
curl -sS -D - "https://api.domain.com.au/v1/agencies/1"
curl -sS -D - "https://api.domain.com.au/"
```
Observed: `/v1/agencies/1` with GET →
`HTTP/2 401`, `x-domain-security: Unable to verify credentials`,
`{"type":"https://developer.domain.com.au/docs/latest/conventions/access",
"title":"Not Authorized","detail":"Unable to verify credentials"}` — a proper RFC 7807
problem document, with a live docs link, reached by GET. The bare host root `/` →
`HTTP/2 404`, `{"title":"Not Found","detail":"No Matching Route"}`. So across three
paths on one host: an unmapped route is `404`, a GET-routable resource with no
credentials is a documented `401`, and the GET-unsupported search route is a `404`
indistinguishable in shape from the unmapped-root case — an agent can't tell "wrong
method" from "wrong path" without already knowing which routes exist.

How observed: 2026-10-05T10:22:50Z–10:22:52Z and 10:26:40Z, GET (curl 8, default UA,
four requests across three paths on two hosts in the same API family).
