Talqing Python SDK

The Python client for the Talqing /v1 API, generated from openapi/openapi.json. It is the same set of operations, under the same names, as the TypeScript SDK — both are generated from the surface backend/api/dataplane/sdk_surface.py declares.

httpx is the only runtime dependency. Responses come back as decoded JSON, described by TypedDicts: nothing is validated, coerced or renamed on arrival.

Install

pip install talqing

Python 3.10 or newer. The package ships a py.typed marker, so a type checker in your project sees every TypedDict it declares.

To work against a checkout instead: uv pip install -e clients/python.

Authentication

Create a personal access token in the dashboard under Organization → API Tokens. The client sends it as Authorization: Bearer <token>.

from talqing import Talqing

with Talqing(token="tq_...", base_url="https://api.in.talqing.com") as talqing:
    print(talqing.agents.list())

One token reaches every region. A token names your organization, not a region, and every organization exists in every region — so working in a second region is the same token and a different base_url. The resources are separate: an agent you create in https://api.in.talqing.com is not in https://api.us.talqing.com, and neither is its call history or its credit balance.

Talqing.from_env() reads the same two values from TALQING_API_KEY and TALQING_BASE_URL:

export TALQING_API_KEY="your-personal-access-token"
export TALQING_BASE_URL="http://localhost:8000"

with Talqing.from_env() as talqing:
    print(talqing.agents.list())

base_url has no default. A client that quietly points at localhost fails in production as a connection error three layers down; one that refuses to start says what is actually wrong.

The shape of it

Operations are reached by resource, exactly as the API names them:

talqing.agents.list(limit=50)
talqing.agents.get(agent_id)
talqing.agents.versions.rollback(agent_id, 3)
talqing.calls.batches.pause(batch_id)
talqing.telephony.phone_numbers.assign(number_id, agent_id=agent_id)

Path parameters are positional; everything else — request body fields and query parameters alike — is a keyword argument:

agent = talqing.agents.create(
    config={"name": "Support bot", "channel": "text", "prompt": "Be concise."}
)
talqing.agents.update(agent["id"], config={**agent["config"], "greeting": None})
talqing.agents.publish(agent["id"])

An argument you do not pass is not sent. That is what makes a PATCH able to say null:

talqing.telephony.phone_numbers.update(number_id, label=None)  # clear the label
talqing.telephony.phone_numbers.update(number_id, can_outbound=False)  # leave it alone

The one name that is not the API's own is telephony.phone_numbers.import_() — import is a Python keyword.

Errors

Every non-2xx raises TalqingAPIError. There is one error shape, so there is nothing to branch on:

from talqing import TalqingAPIError

try:
    talqing.agents.publish(agent_id)
except TalqingAPIError as error:
    print(error.status_code, error)  # 400 config is invalid
    for problem in error.errors:  # ['llm: unknown model gpt-4.9']
        print(problem)

Pagination

Every list endpoint pages the same way, so one helper covers all of them. Anything else the endpoint filters on passes straight through:

from talqing import paginate

for agent in paginate(talqing.agents.list):
    print(agent["config"]["name"])

for call in paginate(talqing.calls.list, agent_id=agent_id, type="SIP_INBOUND"):
    print(call["id"], call["cost"])

Credits

The platform fee — charged per minute of voice or video, and on nothing else — comes out of a prepaid balance. Provider spend is yours, on your own keys, and never passes through Talqing.

A workspace has one balance per region, so this reads the balance belonging to whichever base_url the client holds. A call placed with nothing left in that region never connects, and reads back with close_reason == "insufficient_credits".

credits = talqing.billing.credits.get()
print(credits["balance"], credits["currency"], credits["voice_minutes_remaining"])

for entry in paginate(talqing.billing.credits.ledger):
    print(entry["created_at"], entry["kind"], entry["amount"], entry["balance_after"])

Buying more is an admin's call, and returns a hosted checkout page to open in a browser. The credit lands in the region you bought it from — balances do not move between regions, so buy against the base URL you meant to top up.

checkout = talqing.billing.credits.checkout(pack="usd_50")
print(checkout["checkout_url"])

Live streams

Six endpoints stay open and push events. Each frame is decoded and repeats its own name in event, which is what tells the frames apart:

for event in talqing.conversations.events(conversation_id):
    if event["event"] == "assistant.delta":
        print(event["text"], end="", flush=True)

Use it as a context manager when the loop may exit early, so the connection closes with it:

with talqing.knowledge.events(kb_id) as events:
    for event in events:
        if event["event"] == "status":
            print("build finished:", event["status"])
            break

Text conversations

Text agents do not use LiveKit rooms. Start a chat, then send it messages — the agent's reply comes back on the same call:

chat = talqing.chats.create(agent_id=agent_id, contact_key="user-42")

turn = talqing.chats.messages.create(
    chat["id"], message="Hello", client_message_id=str(uuid4())
)
for item in turn["items"]:
    print(item["text"])

talqing.chats.end(chat["id"])

A chat stays open until its agent ends it or you call chats.end; that is when its analysis runs and session.completed fires.

Voice and video agents take a LiveKit room token instead:

token = talqing.calls.token(agent_id=agent_id)
print(token["server_url"], token["participant_token"])

Async

AsyncTalqing has the same surface with every operation a coroutine. A stream is the exception: it is not awaited on either client, so async for reads the way for does.

import asyncio
from talqing import AsyncTalqing, paginate_async


async def main() -> None:
    async with AsyncTalqing.from_env() as talqing:
        await talqing.agents.list()

        async for agent in paginate_async(talqing.agents.list):
            print(agent["id"])

        async for event in talqing.copilot.agents.stream(agent_id):
            print(event["event"])


asyncio.run(main())

Types

Every request and response shape is exported from talqing, named as the API names it:

from talqing import AgentConfig, AgentResponse, CallOutcome, OperationRequest

A response is a plain dict at runtime — the TypedDicts describe it for your type checker and your editor, and cost nothing when you run. That also means the SDK can never reject a payload the API considers valid.

Page[T] is the shape every list endpoint returns:

page = talqing.tools.list(limit=50)
page["items"], page["has_more"], page["limit"], page["offset"]

Escape hatches

talqing.request(...) calls a path directly with this client's credentials and error handling, for an endpoint that shipped since this SDK was generated. talqing.http is the underlying httpx.Client, already carrying the base URL and the token, for anything else.

talqing.oauth_start_url(provider) builds the browser redirect that authorizes an integration — not an operation, so nothing generates it.

Regenerating

src/talqing/gen is generated and checked in. After re-running openapi/export.py:

python clients/python/generate.py            # rewrite it
python clients/python/generate.py --check    # or just assert it is current

Everything else in src/talqing is hand-written: the client, the transport, the error, and the pagination helper — what the document cannot say.
