  "abstract": "Which coding agents see the fewest API errors? In October 2026 Cursor had the lowest error rate at 1.0% of calls, and Qwen Code the highest at 10.9%.",
  "whyItMatters": "Error rates reflect the models and providers each agent picks as much as the agent itself. Agents that pin a single busy provider see more rate limits.",
  "questions": [
    "Which coding agent has the lowest error rate?",
    "How often do coding agent API calls fail?",
    "Why does Claude Code see more errors?"
