STRINGX is an API client for the STRING database, built on top of HTTPX.
Inspired on the well-established usability of httpx, stringx provides a clean and easy to use interface to the STRING API while following usage recommendations and best practices:
- Requires client identification;
- Uses POST requests;
- Allows linking to a specific STRING version;
- When applicable, enforces specifying the
speciesparameter.
A customizable client allows targeting any API version and provides support for all output formats available: TSV, JSON, XML, etc...
STRINGX requires Python 3.9+ and is available on PyPI.
$ pip install stringxThe stringx module provides a direct interface to the current API version. JSON is the default response format and can be easily integrated with pandas for further processing.

)Tip
STRING understands a variety of identifiers and does its best to disambiguate your input. Nevertheless, it is recommended to map your identifiers first. Querying the API with a disambiguated identifier (for example 9606.ENSP00000269305 for human TP53) will guarantee much faster server response.
The STRING API requires its callers to identify themselves. To address this, STRINGX enforces that the identity value is set. If done at the module level all subsequent requests will carry this information.
importstringxstringx.identity="my_project_name"You can also identify your clients independently.
importstringxwithstringx.Client(identity="my_project_name") asclient:
...
withstringx.Client(
address="https://version-10-5.string-db.org",
identity="me@example.com"
) asclient:
...Regardless of how you choose to do it, STRINGX always appends its own information to your identity.
Using one of the clients instantiated above as example, the caller_identity parameters passed to the STRING API would be my_project_name (python-stringx/x.y.z).
