# Additional tools

Since IDC data is available via standard interfaces, you can use any of the tool supporting those interfaces to access the data. This page provides pointers to some of such tools that you might find useful.

If you are aware of any other tool that is not listed here, but is helpful for accessing IDC data, please let us know on the [IDC forum](https://discourse.canceridc.dev/), and we will be happy to add it here!

### S3 API

* [**obstore**](https://developmentseed.org/obstore/latest/): open-source Python interface to [Amazon S3](https://aws.amazon.com/s3/), [Google Cloud Storage](https://cloud.google.com/storage), [Azure Storage](https://learn.microsoft.com/en-us/azure/storage/common/storage-introduction), & other S3-compliant APIs, powered by Rust

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://learn.canceridc.dev/data/downloading-data/additional-tools.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
