Layer two is the tool contract: agents should use the OpenAPI spec and CLI/SDK skill files to understand exact requests, responses, auth, errors, and safe execution paths. Do not infer API behavior from prose pages when a schema or skill file is available. Layer three is safety: `/auth.md` explains API-key authentication and high-risk actions; `/pricing.md` explains live pricing signals and marketplace pricing caveats. ## Get Started - [Quickstart](https://docs.vast.ai/documentation/get-started/quickstart.md) - [CLI overview & install](https://docs.vast.ai/cli/get-started.md) - [Python SDK](https://docs.vast.ai/sdk/python/quickstart.md) - [REST API](https://docs.vast.ai/api-reference/introduction.md) - [OpenAPI JSON spec](https://docs.vast.ai/api-reference/openapi.json) — canonical tool contract for REST API requests, responses, auth, and errors - [OpenAPI YAML source](https://raw.githubusercontent.com/vast-ai/vast-cli/master/openapi/yaml/combined_api.yaml) - [API Catalog](https
