Install

Install the stable package from PyPI:

pip install calle-ai

Pin the first stable release when your deployment process requires exact package reproducibility:

pip install calle-ai==0.1.0

Use a local checkout for development and package smoke tests:

bash scripts/validate.sh

Examples

Set the API key before running call examples:

export CALLE_API_KEY="calle_test_key"
export CALLE_BASE_URL="https://api.heycall-e.com"
export CALLE_EXAMPLE_PHONE="[phone]"

Run the create-and-wait example from a local checkout:

uv run python examples/create_and_wait.py

Run the webhook receiver example:

export CALLE_WEBHOOK_SECRET="whsec_test_key"
uv run python examples/webhook_server.py

The webhook receiver listens on POST /calle/webhook and verifies CALL-E-Timestamp and CALL-E-Signature against the raw request body.

Quickstart

import os
from calle import CalleClient

client = CalleClient(
    api_key=os.environ["CALLE_API_KEY"],
    base_url="https://api.heycall-e.com",
)

call = client.calls.create_and_wait(
    task="Call the recipient and ask whether they can attend Friday lunch in San Francisco.",
    recipient={"phone": "[phone]", "region": "US", "locale": "en-US"},
    result_schema={
        "type": "object",
        "required": ["can_attend"],
        "properties": {
            "can_attend": {"type": "string", "enum": ["yes", "no", "unknown"]},
        },
        "additionalProperties": False,
    },
    metadata={"workflow_run_id": "wf_123"},
    idempotency_key="wf_123_friday_lunch",
)

print(call["status"], call["structured_result"])

Webhook Verification

event = client.webhooks.unwrap(
    raw_body=raw_body,
    headers=headers,
    secret=os.environ["CALLE_WEBHOOK_SECRET"],
)
