# YARAify — one `POST` endpoint for everything, Auth-Key required; no GET surface (not asserted — documentation only, no write sent)

YARAify's API documentation page (`https://yaraify.abuse.ch/api/`),
fetched live today, documents a single endpoint,
`https://yaraify-api.abuse.ch/api/v1/`, that handles every operation —
scan a file, query a task ID, query by hash/YARA-rule/ClamAV
signature/imphash/tlsh/telfhash/gimphash/icon-dhash, rescan, **download a
file**, **download an unpacked file**, list/deploy/show/delete YARA rules,
**download a specific YARA rule**, and **download all available YARA
rules** — entirely through `POST` with a JSON `query` field in the body
and an `Auth-Key` request header. There is no documented GET alternative
for any of these, including the two "download" operations that in most
other services of this shape are plain file fetches: the docs' own example
for "download a file" is `curl -H "Auth-Key: ..." -X POST -d
'{"query":"get_file","sha256_hash":"..."}' https://yaraify-api.abuse.ch/api/v1/`.

Per this lane's hard rule against sending any POST/PUT/PATCH/DELETE to a
third-party host, no request was sent to `yaraify-api.abuse.ch`. This
record documents the shape from the live documentation page only — **the
actual auth-refusal and query-response bodies are not asserted** (no live
probe was performed against the API itself, only against the public docs
page that describes it).

The docs page itself states the Auth-Key is obtained free from the same
`abuse.ch Authentication Portal` used by MalwareBazaar/ThreatFox/SSLBL/
Feodo Tracker, and separately gates a paid "enhanced commercial API" for
for-profit use beyond "fair use."

Reproduce (read-only, GET on the docs page itself):
```
curl -s https://yaraify.abuse.ch/api/ | grep -o 'POST \|Auth-Key' | sort -u
# → confirms POST-only + Auth-Key-gated framing documented site-wide
```

How observed: 2026-10-05T11:04:47Z, direct HTTPS GET of the public API
documentation page only (curl, default UA). POST-only, not asserted — no
request of any kind was sent to `yaraify-api.abuse.ch`.
