  title: Featherless AI Serverless Inference Account API
  version: '1.0'
  description: Faithful capture of the publicly documented, OpenAI-compatible serverless inference API operated by Recursal AI, Inc. under the Featherless AI brand. Only endpoints, methods, the Bearer security scheme, and parameters that Featherless publishes in its developer documentation are represented here; request/response schemas are intentionally minimal and honest rather than exhaustive. Base URL and auth per https://featherless.ai/docs/quickstart-guide.

  x-note: Featherless does not publish a machine-readable OpenAPI document (api.featherless.ai/openapi.json -> 404); this is an API Evangelist capture of the documented REST surface, not the provider's own specification.
