# APIs, SDKs & Skills

> Every programmatic way to work with Arize AX at a glance — the REST and GraphQL APIs, the Python, TypeScript, and Go SDKs, the command-line interface, and the skills that drive them from your coding agent.

Arize AX is fully programmable. Whatever your stack, there's an interface for instrumenting, querying, and managing your platform resources from code. This page is the starting point — pick the surface that fits your workflow.

<Tip>
  **Instrumenting an AI app built with an SDK or framework?** Start with the [Integrations overview](/docs/ax/integrations) — it has ready-made tracing setups for OpenAI, LangChain, LlamaIndex, the Vercel AI SDK, and [many more](/docs/ax/integrations). The APIs and SDKs below are for managing platform resources, not for auto-tracing your app.
</Tip>

## Which should I use?

* **Calling from a language we ship an SDK for?** Reach for the **Python**, **TypeScript**, or **Go** SDK first — they wrap the API with idiomatic types and helpers.
* **Working in another language, or want raw HTTP?** Use the **REST API** for resource CRUDL, or **GraphQL** when you need precise, nested queries in a single round trip.
* **Scripting or wiring into CI/CD?** The **CLI** manages resources straight from your terminal.
* **Working in a coding agent?** **Skills** teach Cursor, Claude Code, Codex, or Windsurf to drive these interfaces for you, in natural language.
