- Swap base URL to unlimitedcodex /v1 (or NEXT_PUBLIC_API_BASE_URL).
- Keep OpenAI request shapes for chat, embeddings, and images.
- Replace API keys with delivered ucx_live_ or ucx_test_ credentials.
- Assign least-privilege scopes: chat:write, embeddings:write, images:write, usage:read.
- Store keys server-side only — never in browser bundles or mobile apps.
- Handle stream: true as unsupported (501 streaming_not_enabled).
- Parse x-unlimitedcodex-quota-state on successful responses.
- Branch 429 handling: rate_limit_exceeded vs quota_exceeded codes.
- Review healthy → warning → urgent → blocked thresholds before launch.
- Use separate keys for development, staging, and production.
