The user wants an example using Tailscale. Tailscale has an API (control plane REST API) and a client. I don't have credentials. Building a simple example: a script that uses the Tailscale API requires an API key (OAuth client). There's no free sandbox. So realistically I'll be blocked because I don't have credentials. Let me check the environment: is tailscale available? Let me quickly check the network and environment.
I should be honest: without credentials, I can't actually run against the hosted product. However, I can write an example script (SDK client) and explain the pricing and ease of use. The instructions say "let me know if you get blocked." So I'll check whether credentials/network are available.
Let me quickly poke around the environment.

The network is working (the 404 from the API means it's reachable). The repo is empty. No tailscale binary, no credentials either. In other words: I can write sample code using the Tailscale API, but can't execute it without an OAuth client/API key. Does Tailscale have official SDKs? There's community SDKs, plus tsnet (Go), tailscale-client-go v2, and tailscale-client-python. The simplest thing is: a plain HTTP API script, or a Python example.
I can write a small sample using the REST API (or the official Python client tailscale-client-python v2). Should I check whether pip install works? Might be able to try quickly. But without credentials it won't run either way. Write the example, explain pricing and ease of use, and mention the credential-based blocker.
Pricing: Tailscale has a Free plan (up to 3 users, 100 devices), Personal, Starter ($6/user/month), Premium ($18/user/month), Enterprise. Should be careful about accuracy — prices change. Mention roughly the latest known values: Free (3 users, 100 devices), Personal ($?, actually the Personal plan is roughly up to 5 users… recent plans: Free, Personal, Starter $6/user/month, Premium $18/user/month). Let's keep it approximate and recommend checking the pricing page.
Build the example: a script tailscale_example.py that uses the API via requests: list devices, create an auth key, etc. Or the official Python SDK tailscale-client-python v2. Could install it just to show it works and verify the import. Quickly: pip install tailscale-client-python? Let's try briefly.

Can't install via pip (probably due to network restrictions to PyPI). No problem — I'll use requests and write examples against the REST API. Check whether requests is available.

PyPI is blocked, but api.tailscale.com is reachable. Writing a sample that uses plain requests against the Tailscale REST API. This doesn't require a local service stack — it communicates with the hosted control plane. However, running it requires OAuth credentials (TS_OAUTH_CLIENT_ID/SECRET or an API key). I'll write the script, document the procedure, and honestly report that I'm blocked at the execution stage due to lack of credentials.
PyPI is blocked here, but api.tailscale.com is reachable and requests is available — so I'll build the example directly against Tailscale's hosted REST API (no local daemon, no tailscaled stack needed).

Also, quickly test the API reachability and display the format of the unauthenticated response? Already received a 404 earlier (that was for a nonexistent tailnet without authentication — probably requires authentication). No problem. I'll report it.
Done. Here's the summary:
What I built — /sandbox/repo/tailscale_example.py: a single-file example against Tailscale's hosted REST API (api.tailscale.com/api/v2). It lists devices on your tailnet and can mint a device enrollment auth key (the key you'd pass to tailscale up --authkey=... on a new machine). No local tailscaled, no service stacks, no long-running processes — just HTTPS calls to the control plane.
Am I blocked? Partially. The API endpoint is reachable from this sandbox, but I can't run the example end-to-end because there are no credentials here (TS_OAUTH_CLIENT_ID/TS_OAUTH_CLIENT_SECRET). Also, PyPI is blocked, so I couldn't install the official Python SDK — I used plain requests instead, which is equivalent. To run it yourself: create an OAuth client in the Tailscale admin console (Settings → OAuth, scopes devices:core:read + optionally devices:authkey:write), export the three env vars, and run the script.
Pricing (verify at tailscale.com/pricing — this changes occasionally):
- Free: up to 3 users, 100 devices — plenty for a personal setup or this example.
- Personal: small paid tier for up to ~5 users with extra features.
- Starter: ~$6/user/month, adds RBAC, key management, more policy features.
- Premium: ~$18/user/month, adds SSO/SAML, posture awareness, subnet routing controls.
- The API itself has no separate cost — it's included with any plan.
Will this be easy for me to manage? Yes, with one caveat. The REST API is clean, well-documented, and scriptable (devices, keys, ACLs, DNS, webhooks), so automation is straightforward — assuming you supply credentials. The caveat: anything involving the data plane (actually enrolling a device, running tailscale up, testing connectivity) requires the client binary running on real machines, which is outside what I can do in this sandbox. Control-plane management: easy. Data-plane ops: on you.
