How this service works
Measures the share held by the largest maintainer from supplied ownership weights. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.
Output
Returns the fractional share (0–1) held by the single largest maintainer by weight, along with any unavailable fields listed in unavailable_fields, and metadata disclosing whether the value is derived or source-backed (including source, time window, and age where applicable).
Example use cases
Supply chain risk audit for a library
“I have a critical open source dependency with four maintainers — their ownership weights are: JohnDoe: 80000, JaneSmith: 10000, devguru99: 5000, patchbot: 5000. What fraction of control does the single largest maintainer have?”
Comparing maintainer diversity across packages
“For package A, the maintainers and weights are: alice: 9000, bob: 500, carol: 500. Compute the top-maintainer concentration so I can compare it to another package.”
Automated SBOM health check pipeline
“As part of our dependency health check, calculate the largest maintainer's share for this package where the maintainers are: org-bot with weight 100000, contrib1 with weight 20000, contrib2 with weight 5000, contrib3 with weight 1000.”
Technical details
Endpoint
POSThttps://dep.halowerk.com/v1/maintainer-concentrationWhen to prefer
Use this endpoint when you have explicit numerical ownership or contribution weights for a package's maintainers and need to quantify concentration risk — specifically the share commanded by the single largest stakeholder. It is ideal for supply chain audits, SBOM health scoring, or automated dependency vetting pipelines where bus-factor and single-point-of-failure risk must be measured programmatically. Prefer it over manual heuristics when you have structured weight data from registries or internal measurements.
Side effects
- Empty or missing maintainers array returns validation error
- All weights zero may produce null or undefined concentration
- More than 10,000 maintainer entries rejected due to maxItems limit
- Negative weights rejected by schema minimum constraint
- Missing required 'name' or 'weight' fields on any item causes request failure
- Network timeout on very large maintainer arrays
