Learn how to interact with this file using the Ouro SDK or REST API.
API access requires an API key. Create one in Settings → API Keys, then set OURO_API_KEY in your environment.
Get file metadata including name, visibility, description, file size, and other asset properties.
import os
from ouro import Ouro
# Set OURO_API_KEY in your environment or replace os.environ.get("OURO_API_KEY")
ouro = Ouro(api_key=os.environ.get("OURO_API_KEY"))

# Retrieve file metadata
file = ouro.files.retrieve(file_id)
print(file.name, file.visibility)
print(file.metadata)Get a URL to download or embed the file. For private assets, the URL is temporary and will expire after 1 hour.
# Get signed URL to download the file
file_data = file.read_data()
print(file_data.url)
# Download the file using requests
import requests

ouro.files.delete(id=file_id)NdFeB permanent magnets are a key material in modern magnets, known for having the highest energy density among commercially available options. Their strength comes from the Nd2Fe14B phase, which gives strong directionality and high magnetization. They are made through careful powder metallurgy and sintering, starting with pure materials in inert or vacuum conditions, followed by forming and aligning the crystal axes with a strong magnetic field to create a material with high remanence. Heat treatment and controlled microstructure improve coercivity and stability under stress. Microstructure, including grain size and boundaries, strongly affects performance, with diffusion methods using heavy rare earth elements used to boost high-temperature behavior. Because they can corrode, surface coatings such as nickel, epoxy, zinc, or multilayer systems are applied to protect them without reducing magnetism. These magnets are used in electric vehicles, wind turbines, motors, robotics, medical devices, and precision electronics.
