zamp-sdk 0.0.8

Customer-facing SDK for executing actions on the Zamp platform

Zamp SDK

The official Python SDK for executing actions on the Zamp platform.

Installation

pip install zamp-sdk

Or with Poetry:

poetry add zamp-sdk

Quick Start

import asyncio
from zamp_sdk import ActionExecutor

async def main():
    result = await ActionExecutor.execute(
        "send_invoice",
        {"invoice_id": "inv_123"},
        base_url="https://api.zamp.ai",
        auth_token="your-api-token",
    )
    print(result)

asyncio.run(main())

Using environment variables

Set ZAMP_BASE_URL and ZAMP_AUTH_TOKEN in your environment, then call without explicit config:

result = await ActionExecutor.execute("send_invoice", {"invoice_id": "inv_123"})

API Reference

ActionExecutor.execute()

@staticmethod
async def execute(
    action_name: str,
    params: Any,
    *,
    base_url: str | None = None,
    auth_token: str | None = None,
    summary: str | None = None,
    return_type: type | None = None,
    action_retry_policy: RetryPolicy | None = None,
    action_start_to_close_timeout: timedelta | None = None,
) -> Any

Parameter	Type	Required	Description
action_name	str	Yes	Name of the registered action to execute
params	Any	Yes	Input parameters for the action
base_url	str | None	No	Zamp API base URL. Falls back to ZAMP_BASE_URL env var
auth_token	str | None	No	API authentication token. Falls back to ZAMP_AUTH_TOKEN env var
summary	str | None	No	Human-readable description of the execution
return_type	type | None	No	Pydantic model to validate the result against
action_retry_policy	RetryPolicy | None	No	Retry configuration for the action
action_start_to_close_timeout	timedelta | None	No	Maximum execution time for the action

RetryPolicy

from zamp_sdk import RetryPolicy

policy = RetryPolicy(
    initial_interval=timedelta(seconds=30),
    maximum_attempts=3,
    maximum_interval=timedelta(minutes=15),
    backoff_coefficient=1.5,
)

# Or use the default configuration:
policy = RetryPolicy.default()

When action_retry_policy is omitted from ActionExecutor.execute(), the SDK applies RetryPolicy.default() automatically — actions fail fast (2 retries + 1 initial attempt) so script failures surface quickly. Pass an explicit policy to opt into longer retries when needed.

Field	Type	Default (via .default())
initial_interval	timedelta	30 seconds
maximum_attempts	int	3
maximum_interval	timedelta	15 minutes
backoff_coefficient	float	1.5

Configuration

Environment Variable	Description
ZAMP_BASE_URL	Base URL of the Zamp API (e.g. https://api.zamp.ai)
ZAMP_AUTH_TOKEN	API authentication token

Explicit parameters passed to ActionExecutor.execute() take precedence over environment variables.

Error Handling

Exception	When
HttpClientError	HTTP request fails (non-2xx status, network error, timeout)
RuntimeError	Action reaches a terminal failure state (FAILED, CANCELED, TERMINATED, TIMED_OUT)
TimeoutError	Polling for action result exceeds the timeout limit
KeyError	Required environment variable is missing and no explicit value was provided

from zamp_sdk.action_executor.utils import HttpClientError

try:
    result = await ActionExecutor.execute("my_action", params)
except HttpClientError as e:
    print(f"HTTP error {e.status_code}: {e.message}")
except RuntimeError as e:
    print(f"Action failed: {e}")
except TimeoutError as e:
    print(f"Timed out: {e}")
