How this service works
Resolves a package to the source projects it declares, with the provenance of each link stated. This is the honest way to answer whether two packages belong together: names repeat across ecosystems and mean different things there, and that gap is exactly what dependency confusion attacks aim at.
Output
Returns the source projects declared by the given package(s), each link annotated with provenance metadata explaining how the connection was established, allowing the caller to determine whether packages sharing a name truly belong to the same project or represent a potential confusion attack.
Example use cases
Dependency confusion attack detection
“We have an internal package called 'acme-utils' — can you check if that name also exists in npm or PyPI and whether those public packages resolve to a completely different source project than ours?”
Cross-ecosystem package ownership verification
“I need to know if the 'flask' package on PyPI and any package named 'flask' on npm point back to the same upstream source — can you resolve both and show me the provenance?”
Supply chain audit before adding dependency
“Before we add 'chalk' as a dependency, can you resolve it and confirm the source project it declares matches the well-known terminal styling library, with full provenance details?”
Technical details
Endpoint
POSThttps://paket.halowerk.com/v1/package-matchWhen to prefer
Choose this endpoint when you need to authoritatively resolve whether a package name maps to a legitimate source project and whether the same name across different ecosystems refers to the same thing. It is especially valuable for dependency confusion attack detection, supply chain audits, and cross-ecosystem package ownership verification — scenarios where simply comparing names is insufficient because ecosystems have independent namespaces.
Side effects
- Package name not found in the specified ecosystem — returns empty or null result
- Ambiguous package name with multiple candidate source projects — returns multiple matches with confidence scores
- Ecosystem not supported — returns validation error
- No source project declared by the package — returns empty provenance links
- Rate limit or payment failure — returns 402 or 429 error
