# Obtaining a PoolTool API Key

You can display the following data for your stake pool on [PoolTool](https://pooltool.io):

* Current block height
* The number of slots in which your stake pool is currently elected to mint blocks

To submit data for your stake pool to PoolTool, you need an API key.

**To get your PoolTool API key:**

1. In your Web browser, navigate to [PoolTool.io](https://pooltool.io/)
2. In the Search field, type your stake pool name or ticker.
3. In the search results, click the **Pool Details** button in the Actions column next to your stake pool.
4. On the Pool Details page, click the **Address Details** button next to the Reward Account or Owner Accounts addresses.
5. On the Address Detail page, click the **Claim Address** button next to the Bech32 address for your stake pool.
6. In the Claim Address dialog, click the **Claim Address** button, then type a secure password for your PoolTool account in the Password field, and then click **Claim Address**
7. Send exactly the amount of ADA requested in the Cardano PoolTool dialog from a payment address for the same wallet as the stake address that you want to claim to the requested address.
8. When the transaction you submitted in step 7 is confirmed, click **Sign In** on the Cardano PoolTool dialog.
9. After signing in, click **Profile** in the left navigation.
10. To get your API key, click the **Copy** button next to the API Key field, and then paste the API key as needed.

For more details on using your PoolTool API key, see the section [Integrating with PoolTool](/coins/overview-ada/guide-how-to-build-a-haskell-stakepool-node/part-iii-operation/configuring-slot-leader-calculation.md#ptintegration)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://www.coincashew.com/coins/overview-ada/guide-how-to-build-a-haskell-stakepool-node/part-v-tips/obtaining-a-pooltool-api-key.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
