Pine Voice SDK for Python

Official SDK for Pine AI voice calls. Make phone calls via Pine's AI voice agent from any Python application — no MCP client or OpenClaw required.

Supports both synchronous and asynchronous usage.

Install

pip install pine-voice

Quick start

from pine_voice import PineVoice

client = PineVoice(access_token="your-access-token", user_id="your-user-id")

result = client.calls.create_and_wait(
    to="+14155551234",
    name="Dr. Smith Office",
    context=(
        "Local dentist office. I'm an existing patient (Jane Doe, DOB 03/15/1990). "
        "Open Mon-Fri 9am-5pm. Dr. Smith is my preferred dentist but Dr. Lee is also fine."
    ),
    objective="Schedule a dental cleaning for next Tuesday afternoon, ideally 2-4pm",
    instructions=(
        "If Tuesday afternoon is unavailable, try Wednesday or Thursday afternoon. "
        "If no afternoons are open this week, take the earliest available afternoon next week. "
        "Confirm the appointment date, time, and dentist name before hanging up."
    ),
)

print(result.transcript)

Authentication

Option A: Pass credentials directly

client = PineVoice(access_token="your-access-token", user_id="your-user-id")

Option B: Use environment variables

export PINE_ACCESS_TOKEN="your-access-token"
export PINE_USER_ID="your-user-id"

client = PineVoice()  # reads from env

Getting credentials

If you don't have credentials yet, use the auth helpers:

from pine_voice import PineVoice

# Step 1: Request a verification code (sent to your Pine AI account email)
request_token = PineVoice.auth.request_code("you@example.com")

# Step 2: Enter the code from your email
credentials = PineVoice.auth.verify_code("you@example.com", request_token, "1234")

# Step 3: Use the credentials
client = PineVoice(
    access_token=credentials.access_token,
    user_id=credentials.user_id,
)

Making calls

Fire and poll

# Initiate (returns immediately)
call = client.calls.create(
    to="+14155552345",
    name="Bay Area Auto Care",
    context=(
        "Local auto repair shop. My car is a 2019 Honda Civic, ~45,000 miles. "
        "Due for a routine oil change and tire rotation. No warning lights or known issues."
    ),
    objective=(
        "Schedule an oil change and tire rotation for this Friday morning, ideally before noon"
    ),
    instructions=(
        "If Friday morning is full, try Friday afternoon. "
        "If Friday is completely booked, try next Monday or Tuesday morning. "
        "Ask for a price estimate for both services combined. "
        "Ask how long the service will take so I know when to pick up the car. "
        "Confirm the appointment date, time, services, and estimated cost before hanging up."
    ),
    caller="communicator",
    voice="female",
    max_duration_minutes=10,
)

# Poll until complete
status = client.calls.get(call.call_id)

Call and wait (SSE with polling fallback)

result = client.calls.create_and_wait(
    to="+14155559876",
    name="Bella Italia Restaurant",
    context=(
        "Italian restaurant in downtown SF. Reservation for Mike Chen. "
        "Party of 4 adults, no children. One guest is vegetarian, one has a nut allergy."
    ),
    objective="Make a dinner reservation for tonight at 7pm for 4 people",
    instructions=(
        "If 7pm is not available, try 7:30pm or 8pm. "
        "If tonight is fully booked, try tomorrow (Saturday) at the same times. "
        "Request a booth or quiet table if possible, but not required. "
        "Mention the nut allergy and ask if they can accommodate it. "
        "Confirm the reservation date, time, party size, and name on the reservation."
    ),
    # SSE is used by default to wait for the final result.
    # Falls back to polling if SSE is unavailable.
    poll_interval=10,  # polling fallback interval (default 10s)
)

print(result.status)          # "completed" | "failed" | "cancelled"
print(result.transcript)      # full conversation
print(result.summary)         # LLM summary (empty unless enable_summary=True)
print(result.credits_charged) # credits used

Async usage

from pine_voice import AsyncPineVoice

client = AsyncPineVoice(access_token="...", user_id="...")

# Auth (async)
request_token = await AsyncPineVoice.auth.request_code("you@example.com")
credentials = await AsyncPineVoice.auth.verify_code("you@example.com", request_token, "1234")

# Calls (async)
call = await client.calls.create(to="+14155551234", name="...", context="...", objective="...")
status = await client.calls.get(call.call_id)
result = await client.calls.create_and_wait(to="+14155551234", name="...", context="...", objective="...")

Both clients support context managers:

# Sync
with PineVoice(access_token="...", user_id="...") as client:
    result = client.calls.create_and_wait(...)

# Async
async with AsyncPineVoice(access_token="...", user_id="...") as client:
    result = await client.calls.create_and_wait(...)

Error handling

from pine_voice import PineVoice, AuthError, RateLimitError, CallError

try:
    result = client.calls.create_and_wait(...)
except AuthError as e:
    # Token expired or invalid — re-authenticate
    print(f"Auth failed: {e.code} {e.message}")
except RateLimitError as e:
    # Too many calls — wait and retry
    print(f"Rate limited: {e.message}")
except CallError as e:
    # Call-specific issue (invalid phone, DND, policy, etc.)
    print(f"Call error: {e.code} {e.message}")

API reference

PineVoice(access_token?, user_id?, gateway_url?)

Synchronous client. Falls back to PINE_ACCESS_TOKEN and PINE_USER_ID env vars.

AsyncPineVoice(access_token?, user_id?, gateway_url?)

Asynchronous client. Same parameters as PineVoice.

PineVoice.auth.request_code(email) -> str

Request a verification code. Returns the request_token.

PineVoice.auth.verify_code(email, request_token, code) -> Credentials

Verify the code. Returns Credentials(access_token, user_id).

client.calls.create(...) -> CallInitiated

Initiate a call. Returns CallInitiated(call_id, status).

Param	Type	Required	Description
to	str	Yes	Phone number in E.164 format. Supported countries: US/CA/PR (+1), UK (+44), AU (+61), NZ (+64), SG (+65), IE (+353), HK (+852)
name	str	Yes	Name of the person or business being called
context	str	Yes	Background context about the callee and info needed during the call
objective	str	Yes	Specific goal the call should accomplish
instructions	str	No	Detailed strategy and instructions for the voice agent
caller	str	No	"negotiator" for complex negotiations (requires thorough strategy in context/instructions). "communicator" for general tasks. Default: "negotiator"
voice	str	No	"male" or "female". Default: "female"
max_duration_minutes	int	No	Max call duration in minutes (1-120). Default: 120
enable_summary	bool	No	Request an LLM-generated summary after the call. Default: False. Most AI agents can process the full transcript directly, so the summary is opt-in to save latency and cost.

client.calls.get(call_id) -> CallStatus | CallResult

Get call status. Returns CallResult if terminal.

client.calls.create_and_wait(...) -> CallResult

Initiate and wait until complete. Returns CallResult.

Uses SSE to wait for the final call result. If the SSE connection fails or the server doesn't support it, automatically falls back to polling. Reconnects once on SSE connection drop before falling back.

Important: Real-time intermediate updates (partial transcripts, "call connected" events) are not currently available. The SSE stream delivers only the final transcript after the call completes. There are no intermediate progress events during the call.

Extra Param	Type	Default	Description
poll_interval	int	10	Seconds between polling requests (fallback only)
use_sse	bool	True	Try SSE first. Set False to force polling.
on_progress	Callable[[CallProgress], None]	None	Callback invoked with a CallProgress object after each poll cycle during polling fallback. Note: real-time progress events are not currently available.

Supported countries

The voice agent can only speak English. Calls can be placed to the following countries:

• US, Canada, and Puerto Rico (+1)
• United Kingdom (+44)
• Australia (+61)
• New Zealand (+64)
• Singapore (+65)
• Ireland (+353)

Calls to numbers outside these country codes will be rejected with a POLICY_VIOLATION error.
