Python SDK

Call MessyAPI from Python.

Install the typed client (Python 3.8+):

pip install https://messyapi.com/pkg/messyapi-1.1.0-py3-none-any.whl
from messyapi import MessyAPI, MessyAPIError

api = MessyAPI()  # reads MESSYAPI_API_KEY
try:
    out = api.normalize_phone(data=[{"phone": "(415) 555-0132 x12"}], options={"field": "phone"})
    print(out)
except MessyAPIError as e:
    print(e.code, e.status, e.request_id)

Retries 429 and 5xx with backoff and honours Retry-After. Every endpoint in the OpenAPI spec has a method; code written for the old zapinner package keeps working.
