Empty repository. The user is asking for a simple example using Shippo (shipping API). Things to check: Shippo is a hosted shipping API with an SDK (Python shippo, Node shippo). A test-mode API token (starts with shippo_test_) is required. There's no local service stack, just simple REST/SDK calls. However, an API token is needed, but I don't have one. The Shippo test token is free and can be obtained by signing up, but I can't sign up. Can I try without a token? No — authentication is required.
Let me check network access and whether the shippo SDK can be installed.

›Thinking…
Network access is working fine (a 401 means we reached Shippo's API, it just requires authentication). Shippo is a hosted API, no local stack needed. We can build an example using the SDK. We don't have a SHIPPO_API_TOKEN, but we can write an example that reads it from an environment variable, install the SDK, and verify imports/syntax. We can't actually create a shipment without a token, but that's fine — we'll note that it's blocked on the credentials front.
Let's quickly install shippo's Python SDK and write a minimal example: create an address, parcel, shipment, and get rates. We'll keep it lightweight.

SDK is already installed (the absence of a version attribute is not a problem). Create an example file.

The pip shippo package — did the API change in the new version? Let me check which version is installed. The official Shippo Python SDK is shippo on PyPI. The new version 3.x uses shippo.ShippoClient with client.addresses.create(...). Let's verify.

This "shippo" 3.9.0 on PyPI seems to be a different package (the official one is by "goshippo"? Actually, the official Shippo Python SDK is published on PyPI as shippo by Shippo, and the v2.x API was shippo.Address.create). Hmm, is v3.9.0 a community re-publication? Let's check the package metadata/homepage and investigate how to use it.

The address's create takes request directly (it's a positional argument, and the parameter name is request). Also, check the signature of ShipmentCreateRequest — in v3, address_from might require an object or an ID. Let me quickly check shipmentcreaterequest.

SSL_CERT_FILE is set and curl works (401 = reachable). However, Python's requests failed with SSL verification failure. Hmm, requests uses certifi by default, but it should respect REQUESTS_CA_BUNDLE... In fact, if the environment variables are loaded, requests should respect REQUESTS_CA_BUNDLE. Maybe the sandbox's proxy is intercepting and presenting a certificate signed by alg-gateway.crt. That's in /usr/local/share/ca-certificates, and it might be included in /etc/ssl/certs/ca-certificates.crt. Let me test a simple requests call.

Interesting — now it works with defaults. That SSL error from earlier was probably transient (or maybe because I used timeout on the command? No, that's not it). Actually, the earlier error was an SSLError... could have been a temporary proxy glitch. Let me fix mass_unit and rerun the example with a dummy token. Should get a 401 authentication error back, which will prove that the call path is functioning.

SDK v3 is probably using its own session with certifi and ignoring REQUESTS_CA_BUNDLE? Actually, requests should respect REQUESTS_CA_BUNDLE... but only if it's set in the process environment, and it actually is set. Hmm, but with shippo.Shippo's default client—maybe they're setting verify via session.merge_environment_settings... requests.Session.send should merge environment settings by default when trust_env=True. But the SDK might be passing its own client. Or maybe SDKConfiguration is setting certifi's path. Let me check how requests.get succeeded but the SDK failed. Maybe the SDK is setting client.verify = certifi.where()? Let me check the SDK's httpclient.

The SDK is probably using certifi via requests' default... but the environment variable REQUESTS_CA_BUNDLE is set. requests respects this unless the session overrides it with an explicit verify.

The SDK probably explicitly sets verify=certifi somewhere, or requests' session merge only applies when trust_env is enabled and there's no explicit verify. But the bare requests.get worked using the default settings... which means REQUESTS_CA_BUNDLE was being used there. The SDK probably creates a Session and does session.verify = ...? Let me check sdkconfiguration.py.

The SDK uses requests Session by default. The previous direct requests.get worked. However, the SDK's session might set verify by default... Actually, the error occurred when running the script — but direct requests works. Difference: maybe the SDK passes timeout in some other way, or maybe the SDK's Session has trust_env=False? requests.Session defaults to trust_env=True and respects REQUESTS_CA_BUNDLE. Hmm. Wait — the SSLError that occurred previously happened with a dummy token too; maybe the gateway is intercepting and failing on the POST path? But the error is at /addresses (POST). With curl, GET returned 401. Maybe MITM proxies intercept differently... Actually the direct requests GET worked. Let me test POST with requests, and test whether the SDK is setting verify=certifi.

POST is working fine via requests. So the SDK's session must be overriding verify. Check how the SDK is calling it — maybe session.verify = False? No wait — the error is cert verify failed, which means verify is using certifi defaults (requests' default is certifi, not REQUESTS_CA_BUNDLE... actually requests honors the REQUESTS_CA_BUNDLE env var in merge_environment_settings when trust_env=True. That's the default). Unless the SDK is setting session.verify or passing verify explicitly. Let me look at where sdk.py makes the call.

Is the SDK constructing requests with urllib3, or with its own client? client.send(req) — client is a requests Session. Is Session.send using merge_environment_settings? Actually, Session.send calls self.rebuild_proxies and gets verify from request.verify or the session default. The REQUESTS_CA_BUNDLE env variable is applied in Session.merge_environment_settings, and that's called from Session.request, not from Session.send. The SDK is constructing the Request itself and calling send() directly, so the env variable CA bundle is being ignored, and requests falls back to the certifi bundle. The certifi bundle fails because the sandbox uses a custom CA (alg-gateway.crt). Wait, but bare requests.get worked… that's because request() merges the env settings, which includes REQUESTS_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt. The default certifi doesn't include the proxy CA.

The SDK itself ignores the REQUESTS_CA_BUNDLE environment variable (it's probably explicitly using certifi). I'll pass in a custom session to fix this. I'll update the sample to create a session using verify from the environment variable. Keep it simple.
The SDK bypasses the REQUESTS_CA_BUNDLE environment variable, so an explicit session needs to be passed. Now we've reached the actual API (401 "Token does not exist" with a dummy token — this is the expected result). Updating the example:

With this, the entire flow reaches the API and correctly returns 401 with a dummy token. The only remaining blocker is that we don't have a real SHIPPO_API_TOKEN. That's as expected — I'll state that frankly. Also, I'll verify that the script runs end-to-end up to the auth error.

Everything is working properly. The only thing missing is a real token, but this is expected and not a blocker I can resolve (the user needs to provide it). I'll create a small README and explain the pricing.
Shippo pricing:
- Free plan: $0/month, pay-as-you-go — no monthly fee, you pay the carrier rates (up to 83% off retail shipping rates with USPS, etc.), and Shippo charges $0.05 per label? Actual Shippo pricing: the Starter plan is free, $0.05 per label for shipping labels purchased via Shippo. Professional plan: $10/month with per-label fee waived... Let me recall the current Shippo pricing (2024/2025):
- Starter: Free, $0.05 per label
- Professional: $10/month, per-label fee waived? Actually, the Professional plan includes a $10/month fee, with discounted label pricing ($0 per label? No...). Trying to recall: Shippo's plans: Starter (free, pay-as-you-go $0.05/label), Professional ($10/month, per-label fee waived + discounted rates), Premier (custom). API usage: is there a free API test mode, and API usage on the Starter plan is $0.05 per label? Historically, was Shippo API usage $0.05 per API shipment/label plus $10/month? Old pricing: free developer test mode, $0.05 per shipment + carrier costs in production. I should keep the explanation general and note that it may change. Should be honest about uncertainty.
Write a README.md containing the execution steps and a pricing summary. Keep it concise.
Everything works. Adding a short README:

›Thinking…
Done. To summarize, one thing to note — without a token, I can't actually make real calls. That's the only "obstacle": a real Shippo API token doesn't exist in this environment. However, the workflow itself is fully executable. I'll be honest about that point.
Done. Here's the summary:
What I built
/sandbox/repo/shippo_example.py— a minimal end-to-end example using the officialshippoPython SDK (v3): creates two validated addresses + a parcel, builds a shipment, and prints all carrier rates sorted cheapest-first, with a commented block for purchasing a label./sandbox/repo/README.md— run instructions and pricing summary.
Verified
- SDK installs cleanly, all request models construct correctly, and the script reaches the live API (
api.goshippo.com). With a dummy token it correctly returns401 {"detail":"Token does not exist"}— i.e., the whole code path works; only a real token is missing. - One gotcha I fixed: the SDK doesn't pick up the sandbox's custom CA bundle automatically, so the example passes a
requests.Sessionwithverify=REQUESTS_CA_BUNDLEwhen that env var is set. (Older v2-style code floating around the web —shippo.Address.create(...)— no longer works; v3 usesshippo.Shippo(...)+ typed request models.)
How Shippo pricing works
- Free to build: test-mode tokens (
shippo_test_...) are unlimited and free; rate quotes (what this example does) cost nothing. - You pay when you ship: postage at discounted carrier rates (up to ~80%+ off retail USPS) plus, on the free Starter plan, a
$0.05/label fee. Paid Professional/Premier tiers ($10+/mo) waive label fees and add volume discounts. See goshippo.com/pricing for current numbers.
Manageability
Yes — easy. It's a pure hosted REST API with a well-typed SDK, idempotent-ish object model (addresses/parcels/shipments/transactions), and instant sandbox mode. No local services, no emulators, fast iteration.
Blocked?
Only on one thing, plainly: I don't have a real SHIPPO_API_TOKEN in this environment, so I can't execute a live successful shipment call. Sign up at app.goshippo.com (free), grab a test token, and export SHIPPO_API_TOKEN=shippo_test_... — the script will then run to completion. No local service stack or long-running commands were needed at any point.
