# Introduction

> Vikey is one API key for Claude, GPT, DeepSeek and other AI models, compatible with the OpenAI and Anthropic formats, paid in Rupiah.

Vikey is an AI inference API. With one API key you can call Claude, GPT, DeepSeek, Kimi, GLM, Qwen, Gemini and more. Your balance is in Rupiah, topped up with QRIS from Rp10.000.

Vikey uses the same API formats as OpenAI and Anthropic. The code, SDKs and coding agents you already use only need two changes: the **base URL** and the **API key**.

## The essentials

| Item | Value |
| --- | --- |
| Base URL, OpenAI format | `https://api.vikey.ai/v1` |
| Base URL, Anthropic format | `https://api.vikey.ai` |
| Authentication header | `Authorization: Bearer API_KEY` or `x-api-key: API_KEY` |
| Model id shape | `provider/name`, for example `anthropic/claude-sonnet-5.5` |
| Model list | `GET https://api.vikey.ai/v1/models` or the [pricing page](https://vikey.ai/en/pricing) |

## Where to start

- [Quickstart](/en/quickstart/): Sign up, top up, create an API key and send your first request.
- [Claude Code](/en/agents/claude-code/): Use Vikey in Claude Code, including model settings.
- [Codex CLI](/en/agents/codex/): Add Vikey as a model provider in config.toml.
- [opencode](/en/agents/opencode/): A Vikey provider in opencode.jsonc, tested on the latest release.
- [Vikey Auto](/en/models/vikey-auto/): One model id. Vikey picks a light, medium or heavy model per task.
- [Set up with an AI agent](/en/setup-with-ai/): Have your agent read these docs and configure itself.

## For AI agents

Every page in these docs is also available as plain Markdown. Add `.md` to the URL, for example `https://docs.vikey.ai/en/agents/claude-code.md`. A summary of all docs is at [`/llms.txt`](/llms.txt) and the full text at [`/llms-full.txt`](/llms-full.txt) (Indonesian edition).
