Data Sources

@ccusage/codex reads local Codex session logs and reports daily token usage.

A local sync script writes sanitized daily aggregates into Firestore. The website reads those aggregates through api.brandonszeto.com; raw Codex logs are not published.

Cost values are estimates based on the model pricing table used by @ccusage/codex.
