Use reference for exact answers
Reference pages describe the current Singular contract without assuming full compatibility from an endpoint name. Use them while implementing, debugging, or verifying a client.
| Need | Reference |
|---|---|
| Stable request and response fields | Chat Completions |
| OpenAI, Anthropic, Gemini, and media boundaries | Compatibility matrix |
| Singular-specific selection controls | Routing controls |
| SSE framing, errors, and retries | Streaming and errors |
| Prepaid balances, prices, and usage | Billing and usage |
| Known unsupported or incomplete behavior | Limitations |
| Agent-readable indexes and full corpus | LLM-readable documentation |
Read status literally
Stable applies only to the documented surface. Limited identifies a usable but constrained surface. Deployment gated requires the active deployment to advertise and satisfy the feature. Informational pages organize verified facts without claiming a separate runtime contract.

01Chat CompletionsThe stable data-plane contract, its supported parameters, response shape, and current compatibility boundaries.02Compatibility matrixKnow exactly which OpenAI, Anthropic, Gemini, and media-shaped routes are production-ready.03Routing controlsUse fallback model lists, routing profiles, provider preferences, and the supported model suffixes.04Streaming & errorsParse Singular's Chat Completions SSE stream correctly and retry only failures that can reasonably recover.05Billing & usageUnderstand the live retail price source, balance-backed requests, and the difference between authoritative totals and UI estimates.06LimitationsWhat is implemented, what is partial, and which attractive-looking UI or route surfaces are not release-ready.07LLM-readable docsUse the concise index for discovery and the full text bundle when a task genuinely needs the complete contract.
