AI provider settings

Every setting below is read from the environment variable in the second column, or from the same key in a YAML configuration file. An unrecognised FANOUT_-prefixed variable is a startup error, so a renamed setting surfaces as a refusal to start rather than as a default nobody chose.

Setting	Environment variable	Type	Default
ai.api_key	FANOUT_AI_API_KEY	string · secret	—
ai.base_url	FANOUT_AI_BASE_URL	string	—
ai.model	FANOUT_AI_MODEL	string	—
ai.provider	FANOUT_AI_PROVIDER	string	anthropic

Secrets

Settings marked secret are redacted from Fanout’s startup configuration log. They are still plain environment variables: anything that can read the process environment can read them.
