pridefetch 0.5.0

Python API for fetching PRIDE Archive dataset files.

PrideFetch

PrideFetch is a Python API package for discovering and downloading PRIDE Archive dataset files. It wraps the PRIDE REST API, resolves file download URLs, and provides parallel downloads with resume support.

Installation

pip install pridefetch

Quick Start

from pridefetch import list_raw_files, download_files

accession = "PXD032067"
files = list_raw_files(accession)

results = download_files(
    accession,
    files,
    output_dir="./downloads/PXD032067",
    overwrite=False,
    resume=True,
    workers=4,
    show_progress=False,
    verify_checksums=True,
)

print(results)

Authenticated Access

PrideFetch supports API key authentication using a configurable header.

from pridefetch import AuthConfig, PrideFetchClient

auth = AuthConfig(api_key="your-token", header_name="X-API-Key")

with PrideFetchClient(auth=auth) as client:
    files = client.list_raw_files("PXD032067")
    results = client.download_files("PXD032067", files)

You can also load credentials from environment variables:

export PRIDEFETCH_API_KEY="your-token"
export PRIDEFETCH_API_KEY_HEADER="X-API-Key"

from pridefetch import PrideFetchClient, load_auth_from_env

with PrideFetchClient(auth=load_auth_from_env()) as client:
    project = client.fetch_project("PXD032067")
    print(project["title"])
