phidown

phidown is a Python package and CLI for searching and downloading Copernicus Data Space products and PhiSat-2 INSULA platform files.

It supports:

• Product search through the CDSE STAC API (collection, dates, AOI, orbit direction, cloud cover). Results keep the OData-style columns (Id, Name, S3Path, ContentDate, GeoFootprint, Attributes). Queries that STAC cannot answer fully use OData instead: name patterns, Sentinel-1 RAW and non-COG GRD, collections outside Sentinel-1/2/3/5P/6 and COP-DEM, large Sentinel-2 L2A pages, and most attributes.
• Product download through S3 (s5cmd).
• PhiSat-2 search and download through the INSULA platform.
• Sentinel-1 SLC burst search and burst coverage analysis workflows.

Installation

From PyPI

pip install phidown

Optional dependency groups

# Visualization and mapping tools
pip install "phidown[viz]"

# AIS-related utilities
pip install "phidown[ais]"

# Jupyter environment helpers

From source (uv)

git clone https://github.com/ESA-PhiLab/phidown.git
cd phidown
uv sync

Requirements:

• Python 3.10+
• s5cmd available on your PATH for S3 downloads

As a Codex plugin

This repository now ships a repo-local Codex plugin and marketplace:

• plugins/phidown/
• .agents/plugins/marketplace.json

To install it from this repository:

1. Clone the repository and open the repo root in Codex.
2. Restart Codex if the plugin directory was already open before these files existed, so Codex reloads the repo marketplace.
3. Open the Codex plugin directory and select the Phidown Plugins marketplace.
4. Install the Phidown Downloader plugin.
5. Start a prompt such as:

Use $phidown to search Copernicus products and download data via phidown CLI or Python.

If you manage marketplaces from the Codex CLI, you can also add this repository as a local marketplace root:

codex plugin marketplace add /absolute/path/to/phidown

Local agent skills

Install the bundled phidown guidance for local agentic tools:

phidown skill add                 # Codex: $CODEX_HOME/skills/phidown
phidown skill add --engine claude # Claude Code: ~/.claude/skills/phidown
phidown skill add --engine cursor # Cursor project rule: .cursor/rules/phidown.mdc
phidown skill add --engine all

Remove the local files with the matching command:

phidown skill remove --engine all

Credentials

Create a shared .s5cfg file for both CDSE and PhiSat-2. Keep the existing [default] block for CDSE, then insert the [phisat2] block directly below it in the same file:

[default]
aws_access_key_id = your_access_key
aws_secret_access_key = your_secret_key
aws_region = eu-central-1
host_base = eodata.dataspace.copernicus.eu
host_bucket = eodata.dataspace.copernicus.eu
use_https = true
check_ssl_certificate = true

[phisat2]
username = [email protected]
password = your_password
base_url = https://phisat2.insula.earth
api_base = https://phisat2.insula.earth/secure/api/v2.0
authorization_endpoint = https://identity.insula.earth/realms/phisat2/protocol/openid-connect/auth
token_endpoint = https://identity.insula.earth/realms/phisat2/protocol/openid-connect/token
redirect_uri = http://localhost:9207/auth
client_id = api-client

If credentials are not removed automatically, revoke them in the CDSE S3 Credentials Manager: https://eodata-s3keysmanager.dataspace.copernicus.eu/panel/s3-credentials

phidown --reset updates only the active provider section, so CDSE and PhiSat-2 credentials can coexist safely in one file.

Quick Start (Python API)

from phidown.search import CopernicusDataSearcher

searcher = CopernicusDataSearcher()
searcher.query_by_filter(
    collection_name="SENTINEL-1",
    product_type="SLC",
    start_date="2024-05-01T00:00:00",
    end_date="2024-05-31T23:59:59",
    top=50,
)

df = searcher.execute_query()
print(f"Results: {len(df)}")
print(searcher.display_results(top_n=5))

Sentinel-1 burst mode

from phidown.search import CopernicusDataSearcher

searcher = CopernicusDataSearcher()
searcher.query_by_filter(
    burst_mode=True,
    swath_identifier="IW2",
    polarisation_channels="VV",
    orbit_direction="DESCENDING",
    start_date="2024-08-02T00:00:00",
    end_date="2024-08-15T00:00:00",
    top=20,
    count=True,
)

df = searcher.execute_query()
print(f"Bursts found: {len(df)}")

PhiSat-2 search

from phidown.search import CopernicusDataSearcher

searcher = CopernicusDataSearcher()
searcher.query_by_filter(
    collection_name="PHISAT-2",
    product_type="L1",
    aoi_wkt="POLYGON((-3.90 40.30, -3.50 40.30, -3.50 40.70, -3.90 40.70, -3.90 40.30))",
    start_date="2026-05-01T00:00:00Z",
    end_date="2026-05-30T23:59:59Z",
    top=10,
    config_file=".s5cfg",
)

df = searcher.execute_query()
print(df[["Id", "coverage", "Name", "ContentDate", "DownloadUrl"]].head())
