Providers and BYOK

Use the provider catalogs before configuring an assistant: GET /catalog/providers/llm, /asr, /tts, and /audio-to-audio return the supported choices.

AI4CALL can supply selected providers. Bring-your-own-key (BYOK) providers are managed with the Provider Wallet: list the catalog, create a wallet entry, then read, update, or delete it under /account/provider-wallet.

Service	AI4CALL and BYOK	BYOK only
LLM	OpenAI	OpenRouter, Ollama, Google, Anthropic, Mistral
ASR	Azure, OpenAI Whisper	Mistral
TTS	Azure, Google	ElevenLabs, Mistral

The live catalog is authoritative: provider availability can vary by account and model, so always use its availableModes before presenting a choice in your application.

Provider keys are write-only. Store the original value securely; do not expect the API to return it later. Attach the selected provider through the corresponding assistant runtime endpoint.
