faa-drs

CI PyPI Python

Python SDK for the FAA Dynamic Regulatory System (DRS) API.

Documentation: https://cldixon.github.io/faa-drs/

Install

uv add faa-drs

Set the API key

Get a key from the DRS API page in DRS Help & Training. Then set the key in the environment:

export DRS_API_KEY="your-key"

Use

from faa_drs import DRSClient, DocType

with DRSClient() as drs:
    for doc in drs.iter_documents(DocType.AC, filters={"drs:status": "Current"}):
        print(doc.number, doc.title)
        drs.download_to(doc, "downloads/")

The client:

  • Gets all pages for you. The API returns a maximum of 750 documents per page.
  • Validates filters against the document type before it sends a request.
  • Retries connection errors, timeouts, HTTP 429 and HTTP 5xx.
  • Returns typed models. doc.content contains the full text when the API supplies it.

An async client, AsyncDRSClient, has the same methods.
