How do I use Code Buckets from Python?

import os, requests
CB = "https://api.codebuckets.clatterlabs.xyz"
H = {"Authorization": f"Bearer {os.environ['CLATTER_API_KEY']}",
     "X-Clatter-Account": os.environ["CLATTER_ACCOUNT_ID"]}

projects = requests.get(f"{CB}/v1/projects", headers=H).json()["data"]
print([p["name"] for p in projects])

For uploads, copy the complete uploader from the Uploads guide: it sends 4 chunks in parallel, checks SHA-256 and can resume.
