Cause (Documented platform behavior): api_bridge collapses all these billing codes into CodexErr::QuotaExceeded, hiding which one fired.
Fix status: documented_behavior
Limitations:
- API-side quota message is sourced from a Codex test fixture, not an OpenAI error doc.
Other error fragments:
- You exceeded your current quota, please check your plan and billing details.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/openai/codex/main/codex-rs/codex-api/src/api_bridge.rs (official_docs, 2026-09, documented_behavior): api_bridge maps insufficient_quota and credit_balance_exhausted / organization_spend_limit_exceeded / project_spend_limit_exceeded / organization_usage_limit_exceeded to QuotaExceeded.
- https://raw.githubusercontent.com/openai/codex/main/codex-rs/protocol/src/error.rs (official_docs, 2026-09, documented_behavior): QuotaExceeded Display text.
- https://raw.githubusercontent.com/openai/codex/main/codex-rs/codex-api/src/sse/responses.rs (official_docs, 2026-09-27, documented_behavior): Test fixture for insufficient_quota uses the API message 'You exceeded your current quota, please check your plan and billing details.'

Proposed fix: [Codex CLI] 'Quota exceeded. Check your plan and billing details.' — API-key org/project out of credits or over spend limit (insufficient_quota and 4 other codes collapsed)
Recommended action: Check the org/project billing, credit balance and project spend limits for the key; raise limits or add credits.
Option: Check the org/project billing, credit balance and project spend limits for the key; raise limits or add credits. [evidence: official_recommended_action]
Applies when: Running codex with an OpenAI API key
Steps:
1. Check org credit balance for the key's org
2. Check project-level spend limits too
3. Retry after adding credits or raising the limit
Expected: The error no longer appears.
