Manage files Api Routes Upload File.

Contract-preserving POST Endpoint for files Api Routes Upload File in the Mistral AI API. Model and resource-specific values are supplied by the caller at runtime.

All 238 ApiKey-authenticated Mistral AI Platform REST endpoints from a fixed Apache-2.0-licensed official revision, including typed SSE streaming and Workflows. Hub provides documentation and an independent SDK/CLI, but never proxies model, account, or usage data; callers connect directly with local API keys.
