CactusKIT SDK package

CactusKIT

Lightweight Python SDK for declaring small API handlers and producing consistent responses.

See package metadata in pyproject.toml.

Quick links

• Source: https://github.com/qerdinger/cactuskit
• Requires: Python 3.10+

Overview

CactusKIT provides a single-purpose decorator cactuize to declare API entrypoints and a small response wrapper CactusResponse so handlers return consistent, serializable objects.

Key pieces:

• cactuize(...) : decorator that validates/binds args, optionally enforces auth, and normalizes return values into CactusResponse.
• CactusResponse / make_res() : response object and factory with helpers (size, hash, timestamp).
• CactusEncoder : JSON encoder that can serialize CactusResponse instances.
• Enums: HttpStatus, ApiProtocol, ApiMethod.

Installation

Install from source or PyPI when available:

pip install cactuskit

Usage

Import the symbols from the module and declare handlers with cactuize.

from cactuskit import ApiMethod, ApiProtocol, HttpStatus, cactuize

def authenticate():
    return True

@cactuize()
def simple_entrypoint():
    return f"Hello World from {simple_entrypoint}"

@cactuize(
    auth=authenticate,
    protocol=ApiProtocol.HTTP,
    method=ApiMethod.GET)
def entrypoint(name):
    return (HttpStatus.HTTP_CUSTOM(201), {
        "content": f"Hello {name}"
    })

Notes:

• Handler functions may return a plain payload (dict or str) or a tuple (HttpStatus, payload).
• If auth is provided to cactuize, it should be a callable returning truthy when authorized.

API Reference (short)

• cactuize(protocol=ApiProtocol, method=ApiMethod, auth=None, middleware=None, args_mtable=None) : declare a function as a Cactus entrypoint. Performs argument binding and converts results into CactusResponse objects. When auth is provided, it is called and a failed check returns a plain "Authentication required" string.
• CactusResponse(payload, status_code) : wrapper with helpers: get_payload(), get_status_code(), get_timestamp(), get_payload_size(), get_payload_hash().
• make_res(payload, status_code=HttpStatus.HTTP_OK) : helper factory.
• CactusEncoder : json.JSONEncoder subclass that serializes CactusResponse instances.

Development

• Create a virtualenv and install dev dependencies (if any).

python -m venv .venv
source .venv/bin/activate
pip install -e .
