Venice Characters

Characters are published personas on Venice — each one bundles a system prompt (plus optional context), a suggested backing model, and metadata (tags, ratings, adult / web flags). You apply a character to a chat by passing its slug via venice_parameters.character_slug.

Use when

• You want to build a character-selection UI or discovery surface.
• You want to ship an app with a preset persona (e.g. a coding coach, a philosopher, a game NPC).
• You want to pick the right model for a character (the character's modelId is a suggestion; you choose the chat model).

Three endpoints, all tagged Preview (may change):

Auth: Bearer API key only. These routes do not accept x402 / SIGN-IN-WITH-X (a SIWX-only request gets 401). A request with no Authorization header gets a 402 x402 discovery challenge rather than 401. There is no unauthenticated access. See venice-auth.
