ksapi — Python SDK Quickstart
The official Python client for the Knowledge Stack API. One client authenticates with an API key, ingests documents, asks the agent, and streams chat.
The full per-endpoint reference is generated alongside this package under
./docs/.
Install
pip install ksapi
Authenticate
Mint an API key (in the app under API Keys, or POST /v1/api-keys) and pass it
as access_token. The client sends it as Authorization: Bearer <key> on every
request:
import ksapi
from ksapi.api.documents_api import DocumentsApi
config = ksapi.Configuration(
host="https://api.your-host.example",
access_token="sk-user-...", # your API key
)
client = ksapi.ApiClient(config)
# Smoke test — list documents you can access
print(DocumentsApi(client).list_documents(limit=10).total, "documents")
Browser/session callers authenticate with the ks_uat cookie instead:
ksapi.Configuration(host=..., api_key={"cookieAuth": "<ks_uat value>"}).
Ingest a document and wait until it's searchable
Ingestion is asynchronous. Upload, then poll until the active version's pipeline
status is completed — at that point the chunks are embedded and searchable:
import time
from ksapi.api.documents_api import DocumentsApi
docs = DocumentsApi(client)
with open("contract.pdf", "rb") as fh:
created = docs.ingest_document(
file=fh.read(),
path_part_id="<parent-folder-path-part-id>", # a FOLDER
name="contract.pdf",
)
while True:
version = docs.get_document(created.document_id).active_version
meta = version.system_metadata
status = meta.pipeline_state.status if meta and meta.pipeline_state else None
if status in ("completed", "failed"):
break
time.sleep(2)
print("ingestion:", status)
Ask the agent
from ksapi.api.agent_api import AgentApi
from ksapi.models.ask_request import AskRequest
answer = AgentApi(client).agent_ask(AskRequest(prompt="What are the renewal terms?"))
print(answer.text)
Citation-grounded, multi-turn chat runs through threads; each assistant
message exposes content.citations. Stream those tokens live below.
Stream chat responses (SSE)
The agent streams over Server-Sent Events at GET /v1/threads/{thread_id}/stream.
The generated stream_thread() method buffers the whole response, so consume the
stream directly — the body is data: <json> lines terminated by data: [DONE]:
import httpx
def stream_thread(host: str, api_key: str, thread_id: str):
headers = {"Authorization": f"Bearer {api_key}"}
with httpx.Client(base_url=host, headers=headers, timeout=60) as http:
with http.stream("GET", f"/v1/threads/{thread_id}/stream") as response:
for line in response.iter_lines():
if not line.startswith("data:"):
continue # skip event:/id:/keepalive lines
payload = line[len("data:"):].strip()
if payload == "[DONE]":
return
yield payload # JSON event — parse with json.loads()
for event in stream_thread(config.host, "sk-user-...", "<thread-id>"):
print(event)
Errors
Every error response keeps detail and adds a machine-readable code plus the
request_id (also returned as the x-request-id header) — quote it to support:
from ksapi.exceptions import NotFoundException
try:
DocumentsApi(client).get_document("00000000-0000-0000-0000-000000000000")
except NotFoundException as exc:
body = exc.body # {"detail": ..., "code": "not_found", "request_id": "..."}
print(exc.status, body)
The client raises a typed exception per status: BadRequestException (400),
UnauthorizedException (401), ForbiddenException (403), NotFoundException
(404), ConflictException (409), UnprocessableEntityException (422), and
ServiceException (5xx).
