If you send a catalog id, you get that id or a typed error. We built Conifer as a gateway — one key, OpenAI + Anthropic wires at ` https://api.conifer.build\` — and the named-model contract is the part I'd actually want people to poke. Cursor already speaks those wires, so drop-in is just: export OPENAI_BASE_URL= https://api.conifer.build/v1 export OPENAI_API_KEY=$CONIFER_API_KEY On a named request, `x-conifer-effective-model` equals `x-conifer-requested-model`. There is no public `auto` id. Failover can change the seat (`provider_failover` on the receipt) but not the model. If no admitted seat can serve that exact id, it fails instead of
