weft-sdk for Python
The supported Python buyer client for Weft. Generated OpenAPI APIs remain
available under weft_sdk.generated as an advanced escape hatch.
Install and authenticate
Create a buyer wk_* key in
Dashboard → API keys, then:
pip install weft-sdk
export WEFT_API_KEY="wk_..."
Search
import os
from weft_sdk import Client
api_key = os.environ["WEFT_API_KEY"]
with Client(api_key=api_key) as weft:
account = weft.me()
results = weft.search(query="weather data API", max_results=5)
print(account.data)
print(results.results)
The client defaults to https://weft.network.
Bounded paid fetch
Paid fetches require both a maximum cost and an idempotency key. Reuse the key when retrying the same logical purchase after an uncertain response.
from uuid import uuid4
idempotency_key = str(uuid4())
artifact = weft.fetch(
url="https://merchant.example/data",
max_cost_usd="0.05",
idempotency_key=idempotency_key,
)
Handle API errors
All buyer-client methods raise the same WeftError shape, including the HTTP
status, stable error code, request ID, retry hint, and structured details.
from weft_sdk import WeftError
try:
results = weft.search(query="weather data API")
except WeftError as error:
print(error.status, error.code, error.request_id, error.retryable)
print(error.details)
raise
401: confirm thatWEFT_API_KEYcontains a current buyerwk_*key.403: inspectcodeanddetailsfor an insufficient balance or spending policy denial before changing the request.409(IDEMPOTENCY_CONFLICT): this buyer already used the supplied idempotency key for a different fetch request.
