How this service works
List the RedBTC fixed-price gpt-5.6-luna model. Use before choosing a chat route.
Output
Returns a list of the two RedBTC fixed-price agent models: redbtc/gpt-5.5 (strong chat route) and redbtc/gpt-5.4-mini (cheapest chat route), with their identifiers and relevant metadata for routing decisions.
Example use cases
Choosing a model before agent chat
“What RedBTC models are available right now? I want to see both options before I decide whether to use the cheaper mini or the stronger one for my task.”
Discovering RedBTC chat routes programmatically
“Pull up the RedBTC model list for me so my agent can decide which chat route to call — I need the model IDs to configure the next step.”
Verifying model availability before billing
“Check what models RedBTC currently supports — I want to confirm gpt-5.5 and gpt-5.4-mini are both listed before I commit to a USDC-per-call workflow.”

Use this endpoint when an agent needs to discover or confirm which RedBTC chat models are available before selecting a chat route. Prefer this over hardcoding model IDs to ensure the correct identifiers are used, especially when deciding between cost (gpt-5.4-mini) and capability (gpt-5.5).
