OpenAI API provider

CodexBar's OpenAI API provider targets the API Platform organization dashboard, not ChatGPT/Codex subscription limits.

Data sources

1. Preferred: OPENAI_ADMIN_KEY or configured key with Admin API access.
   • GET https://api.openai.com/v1/organization/costs
   • GET https://api.openai.com/v1/organization/usage/completions
   • Daily buckets use bucket_width=1d, costs are grouped by line_item, and completion usage is grouped by model.
2. Fallback: legacy GET https://api.openai.com/v1/dashboard/billing/credit_grants for normal API keys that cannot access organization usage.

Menu display

• Admin API data renders inline Today/7d/30d KPIs plus a compact 30-day spend chart.
• The inline usage card opens a hosted chart submenu with daily spend, token, and request trends plus selected-day detail.
• Legacy balance data keeps the older available/used credit summary and does not show organization graphs.

Notes

• Costs are the source of truth for financial totals. Token usage and cost buckets can differ slightly from dashboard billing reconciliation.
• Admin API keys are organization-scoped and cannot be used for normal model inference.
