title: Hub API Endpoints agentic-provisioning Buckets API
version: 0.0.1
description: 'We have open endpoints that you can use to retrieve information from the Hub as well as perform certain actions such as creating model, dataset or Space repos. We offer a wrapper Python client, [`huggingface_hub`](https://github.com/huggingface/huggingface_hub), and a JS client, [`huggingface.js`](https://github.com/huggingface/huggingface.js), that allow easy access to these endpoints. We also provide [webhooks](https://huggingface.co/docs/hub/webhooks) to receive real-time incremental info about repos. Enjoy!
The base URL for those endpoints below is `https://huggingface.co`. For example, to construct the `/api/models` call below, one can call the URL [https://huggingface.co/api/models](https://huggingface.co/api/models).
If you''re an Agent, you might prefer the [markdown version OpenAPI spec](https://huggingface.co/.well-known/openapi.md).
