The APIs

Everything the platform does, as an API

Co-pilot APIs

Sessions and messages for all 14 industry co-pilots and 9x Chat, with streaming replies and file or image input.

Model Router

Send a task and let 9xAI choose the model by domain, language, cost and risk. Or pick a model yourself.

Agent APIs

Hand over a goal. Agents plan, use tools and, when the job spans fields, split it across several co-pilots.

RAG and Knowledge

Ground answers in your own documents and data, with the sources cited.

Vision and Document AI

Understand photos and digitise pages, with text and positions returned, in Indian languages too.

9x Code

An AI engineer for your own tooling, from the terminal, VS Code and the browser.

Studio API

Images, video and voice in your product

Create jobs, track them and receive a webhook when they finish. Same credit prices as 9x Studio.

Create a key in 9x Studio and send it as Authorization: Bearer sk_9x_...
Estimate cost first with POST /estimate
Safe retries with an Idempotency-Key header
Webhooks for finished jobs, with delivery history
Per-key monthly credit limits and rate limits
