# The Summer API from Summer Studio

> Signed in to Summer Studio? Open Studio > Developers to connect your coding agent, see every model and its price, and manage each connected app's spend limit.

You are signed in to Summer Studio. Everything your agent needs for the Summer API is one click away, in the same account: the same credits, the same library, the same sign-in.

## Open Studio > Developers

In Studio, open **Developers** ([summerengine.com/studio/developers](https://www.summerengine.com/studio/developers)). It has:

* **Overview**: how to connect Claude Code, Codex, Cursor or Hermes in one command, and the connector address for ChatGPT and Claude.
* **Connected apps**: every agent and app you connected, each with its spend limit, what it spent, and **Revoke**.
* **Usage**: what your agents made and what it cost.
* **Models**: every model with its price, the same list as [models and pricing](https://docs.summerengine.com/api/models.md).
* **Webhooks**: signed notifications when a job finishes.

You can also ask **Ask Summer**, the chat in Studio: "How do I let my coding agent make assets?" It gives you the command for your agent, the models and their prices, and opens Developers.

## Connect your agent

Pick your agent. Each guide is one command and one sign-in:

> **[Claude Code](https://docs.summerengine.com/api/quickstarts/claude-code.md)**

> **[Codex](https://docs.summerengine.com/api/quickstarts/codex.md)**

> **[Cursor](https://docs.summerengine.com/api/quickstarts/cursor.md)**

> **[Hermes](https://docs.summerengine.com/api/quickstarts/hermes.md)**

> **[ChatGPT and Claude](https://docs.summerengine.com/api/quickstarts/chatgpt-and-claude.md)**

When the agent signs in, the browser shows the Summer sign-in page with your Studio account already signed in. Pick a spend limit and choose **Allow**.

## Where things are in Studio

| What | Where |
| - | - |
| Your agents and apps, each with its spend limit and **Revoke** | [Developers > Connected apps](https://www.summerengine.com/studio/developers?section=connected-apps) |
| Credits and top-ups | [Credits](https://summerengine.com/studio/credits) |
| Everything your agent made | Your Summer library in Studio, next to what you made in Studio |

## What it costs

Every model has one public price: the provider's list price. No markup on assets. Your agent prices each job for free before it spends (`summer api estimate`, or [`POST /v1/estimate`](https://docs.summerengine.com/api/jobs#know-the-price-first)), and jobs use your paid Summer credits: your plan's credits and your top-ups.
