The official Python client for accessing the turbopuffer API.
- Install the turbopuffer package and set your API key.
$ pip install turbopufferOr if you're able to run C binaries for JSON encoding, use:
$ pip install turbopuffer[fast]- Start using the API
import turbopuffer as tpuf

# Open a namespace
ns = tpuf.Namespace('hello_world')
# Read namespace metadata
if ns.exists():
print(f'Namespace {ns.name} exists with {ns.dimensions()} dimensions and approximately {ns.approx_count()} vectors.')
