Images captured by cameras directed towards our target volcanoes (currently Cleveland and Okmok, in the Aleutians) are available for browsing and download through our web archive browser, or can be downloaded via our data API using a command line tool, such as cURL, or the Python requests library. 📖 Complete API Documentation: For detailed API reference with interactive examples, see our Visible Imagery API Documentation. An example of how to access the data via the API is shown below: 
import requests

# Query for visible images
response = requests.get(
    "https://avert-legacy.ldeo.columbia.edu/api/imagery/visible/query",
    params={
        "site": "CLNE",
        "vnum": 311240,
        "search_from": "2022-10-01T00:00",
        "search_to": "2022-10-02T00:00",
        "limit": 10  # Control result size
    }
)

images = response.json()

# Download images as ZIP if ≤100 results
if len(images) <= 100:
    zip_response = requests.get(
        "https://avert-legacy.ldeo.columbia.edu/api/imagery/visible/query",
        params={
            "site": "CLNE",
            "vnum": 311240,
            "search_from": "2022-10-01T00:00",
            "search_to": "2022-10-02T00:00",
            "download": True
        }
    )
    with open("visible_images.zip", "wb") as f:
        f.write(zip_response.content)

# Or download individual images
for image in images:
    image_response = requests.get(
        f"https://avert-legacy.ldeo.columbia.edu/api/imagery/visible/r/{image['image_id']}",
        params={"download": True}
    )
    with open(f"visible_{image['image_id']}.jpg", "wb") as f:
        f.write(image_response.content)
