Based on my analysis of your library, here are comprehensive improvement suggestions organized by priority and impact:

  🎯 High Priority Improvements

  1. Enhanced Error Handling & Resilience

  - Add automatic retry with exponential backoff for transient failures (429, 500, 503 errors)
  - Implement circuit breaker pattern to prevent cascading failures
  - Add configurable timeout strategies per operation type
  - Provide better error context with request details in errors

"""
Arithmetic puzzle solver. You are given a sequence of four digits, say 1,2,3,4,
and your job is to combine them with ordinary arithmetic operations (+, -, ×, and ÷)
in any order to make a target number. E.g. 24 = 1 * 2 * 3 * 4 or 24 = (1 + 2 + 3) * 4.

Some 'hard' problems from https://blog.plover.com/math/17-puzzle.html:
    1. Given 6, 6, 5, 2, get 17.
    2. Given 3, 3, 8, 8, get 24.
