# Use Autohand models in other coding agents

Bring Autohand Fantail and Moa to the coding agent you already use. Each guide takes you from a new API key to a working prompt.

Quick answer

## How do I use Autohand models in another coding agent?

Create an API key in Autohand Console, store it in `AUTOHAND_API_KEY`, and add Autohand to the agent as an OpenAI-compatible provider with the base URL `https://api.autohand.ai/v1` and the model ID `fantail` or `moa`. Agents that do not speak Chat Completions connect through a local LiteLLM proxy.

Status

Available for nine coding agents

Requires

An Autohand account and an Autohand API key

Base URL

`https://api.autohand.ai/v1`

Model IDs

`fantail` and `moa`

**Know before you start:** The Autohand API serves the OpenAI Chat Completions format. It does not serve the OpenAI Responses API or the Anthropic Messages API.

## Before you begin

Every guide starts with the same two steps:

1.  Sign in to [Autohand Console](https://console.autohand.ai/). If you do not have an account, sign up first. The Free plan includes Fantail, and Moa requires the Pro plan or above.
2.  Open [API Keys](https://console.autohand.ai/api-keys), create a key for the agent, and store it in the `AUTOHAND_API_KEY` environment variable.

Confirm that the key works before you configure the agent. The request lists the models your plan can use.

```bash
curl https://api.autohand.ai/v1/models \
  -H "Authorization: Bearer $AUTOHAND_API_KEY"
```

## Autohand API at a glance

| Setting | Value |
|---|---|
| Base URL | https://api.autohand.ai/v1 |
| Request format | OpenAI Chat Completions: POST /v1/chat/completions |
| Model list | GET /v1/models |
| Authentication | Authorization: Bearer $AUTOHAND_API_KEY |
| Model IDs | fantail and moa. The API also accepts autohand/fantail and autohand/moa. |

## Choose a model

| Model ID | Use it for | Context | Max output | Plans |
|---|---|---|---|---|
| fantail | Fast agent loops, quick fixes, reviews, and subagents | 256K tokens | 16K tokens | Free and above |
| moa | Planning, large refactors, and repository-wide changes | 1M tokens | 262,144 tokens | Pro and above |

Use Fantail for the main loop and for subagents, which run many short tasks. Use Moa when the agent plans a large change or needs the whole repository in context.

## Supported coding agents

| Agent | Connects through | Subagents on Fantail |
|---|---|---|
| Codex | Local LiteLLM proxy (Responses API) | [agents] default_subagent_model |
| Claude Code | Local LiteLLM proxy (Anthropic Messages API) | CLAUDE_CODE_SUBAGENT_MODEL and subagent model |
| Pi | Direct custom provider | Subagent example extension |
| Hermes Agent | Direct custom endpoint | delegation.model |
| OpenCode | Direct custom provider | agent.<name>.model |
| Kilo Code | Direct OpenAI Compatible provider | See the guide |
| Cline | Direct OpenAI Compatible provider | See the guide |
| Factory Droid | Direct custom model | See the guide |
| Aider | Direct OpenAI-compatible model | See the guide |

Agents that connect directly send Chat Completions requests to Autohand. Codex and Claude Code use other request formats, so their guides add a local LiteLLM proxy that translates each request.

Common questions

## Coding agents and Autohand FAQ

### Do I need an Autohand account?

Yes. You need an account to create the API key that every agent uses.

### Which coding agents work with Autohand models?

Codex, Claude Code, Pi, Hermes Agent, OpenCode, Kilo Code, Cline, Factory Droid, and Aider.

### Why do Codex and Claude Code need a proxy?

Codex uses the OpenAI Responses API and Claude Code uses the Anthropic Messages API. The Autohand API serves Chat Completions, so a local LiteLLM proxy translates the requests.
