CAIDA's AS Rank (`api.asrank.caida.org`) is documented primarily as a GraphQL API, but
it also answers a REST-shaped path, and — usefully for a GET-only agent — the GraphQL
endpoint itself accepts the query as a URL-encoded query-string parameter on GET, no POST
required.

## Probe 1 — REST-shaped path

```
GET https://api.asrank.caida.org/v2/restful/asns/15169
```
→ `HTTP 200`, `{"data":{"asn":{"rank":1556,"asn":"15169","asnName":"GOOGLE","source":"ARIN",
"cliqueMember":true,"seen":true,"longitude":...,"latitude":...,
"organization":{"orgId":"f7b8c6de69"},"cone":{"numberAsns":21,"numberPrefixes":4860,
"numberAddresses":21612800},"country":{"iso":"US"},
"asnDegree":{"total":347,"customer":20,"peer":317,"provider":10}}}}` — despite the "restful"
path segment, the response is STILL wrapped in a GraphQL-shaped `{"data":{"asn":{...}}}`
envelope, not a flat REST object.

## Probe 2 — the actual GraphQL endpoint, via GET with a URL-encoded query param

```
GET https://api.asrank.caida.org/v2/graphql?query=%7Basn%28asn%3A%2215169%22%29%7Basn+rank+asnName+cliqueMember%7D%7D
```
(i.e. `query={asn(asn:"15169"){asn rank asnName cliqueMember}}`, URL-encoded, sent with
`curl -G --data-urlencode`)
→ `HTTP 200`, `{"data":{"asn":{"asn":"15169","rank":1556,"asnName":"GOOGLE",
"cliqueMember":true}}}` — same `rank` (1556) as Probe 1, confirming the two paths read the
same underlying data; only the fields requested differ because GraphQL lets the caller choose
them.

## Known gaps
- `rank` is CAIDA's own topological ranking (customer-cone size based), distinct from any
  commercial "ASN reputation" score; `source: "ARIN"` here is CAIDA's registry attribution for
  AS15169, consistent with Team Cymru's and RDAP's own `arin` attribution for the same ASN in
  other records in this lane.
- Full GraphQL introspection (`__schema`) and mutation support were not probed (read-only
  lane; mutations are out of scope regardless).

How observed: 2026-10-05T08:19:26Z, `curl 8` against api.asrank.caida.org, two GETs (one REST
path, one GraphQL-via-GET), response bodies captured directly above.
