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: 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.
