## Probes

```
GET https://typekit.com/api/v1/json/families/proxima-nova
GET https://typekit.com/api/v1/json/families/vcsm                       (the redirected id)
GET https://typekit.com/api/v1/json/families/zzznonexistentfont9999
```

## Observed

`families/proxima-nova` → HTTP 302, `content-type: application/json`,
`Location: https://typekit.com/api/v1/json/families/vcsm`, body
`{"family":{"id":"vcsm","link":"/api/v1/json/families/vcsm"}}` — the human-readable slug is
resolved server-side to Typekit's internal 4-character family id via a redirect, not served
directly at the slug path.

Following to `families/vcsm` → HTTP 200, `etag` + `cache-control: max-age=0, private,
must-revalidate`, 2,379 bytes of real catalog data: `name: "Proxima Nova"`,
`web_link: "http://fonts.adobe.com/fonts/proxima-nova"`, a `browse_info` block
(`classification: ["sans-serif"]`, `contrast: ["low"]`, `language: [18 codes]`,
`recommended_for: ["headings","paragraphs"]`, `x_height: ["high"]`), `foundry: {"name":"Mark
Simonson Studio","slug":"mark-simonson-studio"}`, and a `libraries` array pointing at further
sub-resources (`/api/v1/json/libraries/full`).

A nonexistent slug (`families/zzznonexistentfont9999`) → clean HTTP 404,
`{"errors":["Not Found"]}` — no key, no auth header, no refusal of any kind.

## Why this matters

Adobe Fonts (formerly Typekit, acquired into Creative Cloud) is commonly assumed to require
authentication for any programmatic access, since actually *using* a licensed web font
(serving via `use.typekit.net/<kitid>.js`) does require a configured kit tied to an Adobe
account. But the **catalog read path** — slug → family metadata, including foundry and
classification data not easily scraped elsewhere — answers every request here without any
credential, rate-limit header, or API key. This overturns this lane's own brief assumption
of an "Adobe Fonts refusal."

How observed: 2026-10-05T09:29:41Z–09:29:57Z, three curl GETs, all anonymous, one redirect
followed manually to confirm the resolved id's body.
