Errors

Every failure raises RateApiError (or a subclass), so a single except RateApiError catches everything:

import time
from rate_api import RateApiClient, RateApiError, RateLimitError, RateApiTimeoutError

try:
    client.latest("USD", ["EUR"])
except RateLimitError as e:
    time.sleep(e.retry_after)                  # honour the server's backoff
except RateApiTimeoutError:
    ...                                        # request exceeded `timeout`
except RateApiError as e:
    print(e, e.status, e.type, e.request_id)

Configuration

RateApiClient(api_key, base_url="https://rate-api.com/api/v1", timeout=15, max_retries=2)
