  "abstract": "How much provider traffic is tool calling? In October 2026 Melious had the highest tool-call share at 66.4% of output tokens and 66.2% of requests. Across the busiest providers, tool calls made up between 7.2% and 66.2% of successful requests.",
  "whyItMatters": "Tool calls are the core loop of agents. Comparing token share with request share shows whether tool-calling turns are longer or shorter than the average response on that provider.",
  "questions": [
    "Which providers handle the most tool calls?",
    "What share of LLM output is tool calling?",
    "Are tool-call responses longer than other responses?"
