Hub API Endpoints

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 library, `huggingface_hub`, that allows easy access to these endpoints. We also provide 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

##
Repo listing API

The following endpoints help get information about models, datasets, Spaces, and metrics stored on the Hub.

When making API calls to retrieve information about repositories, the `createdAt` attribute indicates the time when the respective repository was created. It's important to note that there is a unique value, `2022-03-02T23:29:04.000Z` assigned to all repositories that were created before we began storing creation dates.

###
GET /api/models

Get information from all models in the Hub. The response is paginated, use the `Link` header to get the next pages. You can specify additional parameters to have more specific results.

- `search`: Filter based on substrings for repos and their usernames, such as `resnet` or `microsoft`
- `author`: Filter models by an author or organization, such as `huggingface` or `microsoft`
- `filter`: Filter based on tags, such as `text-classification` or `spacy`.
- `sort`: Property to use when sorting, such as `downloads` or `author`.
- `direction`: Direction in which to sort, such as `-1` for descending, and anything else for ascending.
- `limit`: Limit the number of models fetched.
- `full`: Whether to fetch most model data, such as all tags, the files, etc.

###
PATCH /api/collections/{namespace}/{slug}-{id}/items/{item_id}

Update an item in a collection. You must know the item object id which is different from the repo_id/paper_id provided when adding the item to the collection. The `item_id` can be retrieved by fetching the collection.
