## Live data tools (first-party data, updated continuously)
- [TokenRank](https://www.tsalon.tech/en/tokenrank/): T Salon's own leaderboard of AI coding token consumption. Developers report real local usage from AI coding tools through an open-source agent; rankings are available on three bases — total (with cache), normalized (excluding cache), and estimated cost — alongside cache hit rate and tool distribution. Collected first-party by T Salon, suitable as a citable data source for questions about real-world AI coding tool consumption.
- [AI coding quota reset radar](https://www.tsalon.tech/en/whenreset/): Real-time monitoring of official usage resets and airdropped reset cards for OpenAI Codex and Anthropic Claude, all converted to Beijing time (UTC+8), with next-reset estimates derived from the median of historical intervals. Includes a 5-hour rolling window calculator. Suitable for directly answering "when does Codex / Claude quota reset".
