From Source to Product Signal

Test a Product Idea in Four Steps

deps.dev returns package versions and resolved dependency graphs. Start with one PyPI package version. A dependency edge is not a vulnerability finding; pair this graph with OSV or NVD for exposure, and attribute generated deps.dev data under CC BY 4.0.

1

Check the Setup

  • Python 3.10 or newer
  • A notebook environment such as Jupyter or Google Colab
  • An internet connection
2

Access the Data

  1. 1.Read the v3 API docs and pick one ecosystem, package, and version.
  2. 2.Request the package record, then the version dependencies endpoint.
  3. 3.Keep system, name, version, and relation fields with the retrieval timestamp.

Run the Python Example

Install the packages, then run the notebook cell.

python -m pip install pandas requests

import pandas as pd
import requests

version = requests.get(
    "https://api.deps.dev/v3/systems/pypi/packages/requests/versions/2.32.3",
    timeout=30,
)
version.raise_for_status()
deps = requests.get(
    "https://api.deps.dev/v3/systems/pypi/packages/requests/versions/2.32.3:dependencies",
    timeout=30,
)
deps.raise_for_status()
graph = pd.json_normalize(deps.json().get("nodes", []))
graph["retrieved_at_utc"] = pd.Timestamp.now(tz="UTC")
print(version.json()["versionKey"])
print(graph.head(20))

Test a Useful Signal

Map One Package Version's Resolved Dependencies

Test whether a deps.dev graph can power a bounded supply-chain inventory.

  1. 01Confirm the version key and list direct versus indirect nodes when relation fields exist.
  2. 02Count unique dependency names and flag missing versions.
  3. 03Explain that this graph is not a CVE match and that generated deps.dev data requires CC BY attribution.
