Python SDK and CLI for direct Thalovant hub data-plane clients and agents

Thalovant Python SDK

The Thalovant Python SDK is the developer layer for direct Thalovant hub access. Thalovant provisions client identities and policy; this SDK connects directly to the hub endpoint over the enabled data-plane protocol.

Thalovant API / dashboard -> provision identity, policy, and endpoints
Python SDK / CLI          -> direct hub data-plane connection
Hub runtime               -> skills, events, and replies

Full documentation: docs.thalovant.com/developers/sdks/python

Install

pip install thalovant

For local SDK development:

pip install -e ".[dev]"

Quick Start

Download or copy the client identity created in Thalovant, then:

from thalovant import ThalovantClient

with ThalovantClient.from_identity_file("_identity.json") as client:
    reply = client.ask("Tell me a short clean joke.")
    print(reply.text)

For async apps and agent runtimes:

import asyncio
from thalovant import AsyncThalovantClient


async def main():
    async with AsyncThalovantClient.from_identity_file("_identity.json") as client:
        reply = await client.ask("What time is it?")
        print(reply.text)


asyncio.run(main())

Identity

The identity file uses the same fields produced for Thalovant hub clients:

{
  "access_key": "client-access-key",
  "password": "client-password",
  "crypto_key": "optional-preshared-key",
  "site_id": "my-client-site",
  "default_master": "https://hub.example.com",
  "default_port": 443,
  "default_path": "/public",
  "data_plane_endpoints": {
    "https": "https://hub.example.com/public",
    "wss": "wss://hub.example.com/public",
    "mqtt": "mqtts://mqtt.example.com:8883"
  },
  "protocols": {
    "wss": {"enabled": true},
    "http": {"enabled": true},
    "mqtt": {"enabled": false}
  }
}

Environment variables are also supported:

export THALOVANT_ACCESS_KEY=...
export THALOVANT_PASSWORD=...
export THALOVANT_CRYPTO_KEY=...
export THALOVANT_SITE_ID=...
export THALOVANT_HUB_HTTP_HOST=https://hub.example.com
export THALOVANT_HUB_WSS_HOST=wss://hub.example.com
export THALOVANT_HUB_MQTT_HOST=mqtts://mqtt.example.com:8883
export THALOVANT_HUB_HTTP_PORT=443
export THALOVANT_HUB_HTTP_PATH=/public

from thalovant import ThalovantClient

with ThalovantClient.from_env() as client:
    print(client.ask("Tell me a joke").text)

Keep identity files secret. They are client credentials, not public API keys.

Protocols

The SDK understands the same protocol shape returned by the Thalovant API:

• protocols.wss.enabled controls the public WebSocket path.
• protocols.http.enabled exposes the HTTP protocol as HTTPS at the edge.
• protocols.mqtt.enabled exposes MQTT over TLS when enabled for the hub.

from thalovant import ThalovantIdentity

identity = ThalovantIdentity.from_file("_identity.json")

print(identity.enabled_protocols())
print(identity.endpoint_for("https"))
print(identity.endpoint_for("wss"))
print(identity.endpoint_for("mqtt"))

The current Python runtime transport uses the HTTPS HTTP-protocol endpoint. WSS and MQTT endpoint helpers are exposed so applications can choose a path deliberately and so future transports can share the same identity shape.

Conversations

Use a conversation when multiple messages should share a stable session and correlation context:

from thalovant import ThalovantClient

with ThalovantClient.from_identity_file("_identity.json") as client:
    with client.conversation(lang="en-us") as convo:
        first = convo.ask("Remember that my favorite color is blue.")
        second = convo.ask("What color did I mention?")
        print(second.text)

Conversation helpers add session and request metadata automatically. When the hub echoes that metadata, SDK listeners filter unrelated events from other sessions.

Client Context

Use build_client_context when a web, mobile, kiosk, or service client needs to pass user, device, channel, and platform metadata to skills:

from thalovant import ThalovantClient, build_client_context

context = build_client_context(
    user_id="user-42",
    user_name="Ada",
    auth_provider="oidc",
    roles=["member"],
    platform="kiosk",
    source="checkout-kiosk",
    channel="chat",
)

with ThalovantClient.from_identity_file("_identity.json") as client:
    reply = client.ask("Show the next instruction.", context=context)

Provider-specific fields can still be passed through context or metadata. The SDK keeps the public helper generic.

Actions And Exact Inputs

Use send_action for button/quick-reply payloads, and send_code for exact values such as QR codes, serial numbers, asset IDs, or scanned labels:

with client.conversation(session_id="work-session") as convo:
    convo.send_action('/choose{"id":"42"}', title="Choose item")
    convo.send_code("SN-001-XYZ", kind="qr", label="serial")

Both helpers still emit normal recognizer_loop:utterance events, but add generic input metadata so downstream skills can distinguish typed/scanned values from speech transcription.

Rich Responses

Assistant responses can include text, choices, images, attachments, and tables. Use reply.display_items() or event.display_items() to render a UI without hand-parsing common rich media payloads:

reply = client.ask("Show matching parts.")

for item in reply.display_items(max_text_chars=600):
    if item.kind == "text":
        print(item.text)
    elif item.kind == "choices":
        print([choice["title"] for choice in item.data])

Agents

Use ThalovantAgent for long-running synchronous workers:

from thalovant import ThalovantAgent, EVENT_SPEAK

agent = ThalovantAgent.from_identity_file("_identity.json")


@agent.on(EVENT_SPEAK)
def handle_speak(event):
    print(event.text)


agent.run_forever()

Async agents work the same way:

import asyncio
from thalovant import AsyncThalovantAgent, EVENT_SPEAK

agent = AsyncThalovantAgent.from_identity_file("_identity.json")


@agent.on(EVENT_SPEAK)
async def handle_speak(event):
    print(event.text)


asyncio.run(agent.run_forever())

CLI

The package installs a thalovant command for smoke tests and operational debugging:

thalovant --identity _identity.json doctor
thalovant --identity _identity.json health
thalovant --identity _identity.json ask "Tell me a joke"
thalovant --identity _identity.json listen speak --timeout 30 --max-events 3
thalovant --identity _identity.json emit recognizer_loop:utterance \
  --data '{"utterances":["hello"],"lang":"en-us"}'

Add --json to commands that return structured output.

Events

For common flows, prefer helpers over raw event strings:

from thalovant import EVENT_SPEAK, ThalovantClient

with ThalovantClient.from_identity_file("_identity.json") as client:
    for event in client.listen(EVENT_SPEAK, timeout=30, max_events=1):
        print(event.text)

Use emit when you already know the hub event shape:

from thalovant import EVENT_RECOGNIZER_LOOP_UTTERANCE, ThalovantClient

with ThalovantClient.from_identity_file("_identity.json") as client:
    client.emit(
        EVENT_RECOGNIZER_LOOP_UTTERANCE,
        {"utterances": ["turn on the lights"], "lang": "en-us"},
    )

ThalovantEvent normalizes common fields:

• event.text
• event.utterances
• event.session_id
• event.request_id
• event.is_failure
• event.is_policy_denied

Diagnostics

Use doctor() before debugging application code:

with ThalovantClient.from_identity_file("_identity.json") as client:
    report = client.doctor()
    print(report.format())

The report checks identity shape, endpoint configuration, hub connection, handshake completion, and the live HTTP polling thread.

Documentation

The canonical public documentation lives on the Thalovant docs site:

• Website: docs.thalovant.com/developers/sdks/python

This repository also keeps generated API reference material for maintainers:

• Local preview: pip install -e ".[docs]" && mkdocs serve
• Build check: mkdocs build --strict

Notes

• This SDK is the developer convenience layer. It does not proxy messages through the Thalovant API.
• The Thalovant API remains the control plane for creating clients, rotating or revoking identity material, and managing ACL/policy.
• The data plane is direct hub protocol traffic from this SDK to the hub listener. The SDK reads WSS, HTTPS, and MQTT endpoint metadata from the same identity or hub payload.
