How this service works
Ranks edit-distance proximity between a candidate name and supplied popular package names. 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 a ranked list of popular packages ordered by edit-distance proximity to the candidate name, including the computed distance scores. Missing facts are returned as null and listed in unavailable_fields. Derived values disclose their computation method so callers understand how each score was produced.
Example use cases
CI pipeline typosquat guard
“Before I install 'coloers' as a new npm dependency, check it against these popular packages — ['colors','chalk','ansi-styles','kleur','picocolors'] — with a threshold of 2, and tell me if it's dangerously close to any of them.”
Security audit of suspicious dependency
“We found 'lodahs' in one of our repos and want to know if it's a typosquat — rank its edit-distance proximity against ['lodash','underscore','ramda','immutable','lazy.js'] using a threshold of 4.”
Package name validation before publishing
“I'm about to publish a package called 'expres' to npm — can you check if it's too close to any of these popular packages: ['express','fastify','koa','hapi','restify']? Use an edit-distance threshold of 3 so I know if there's a naming conflict risk.”
Technical details
Endpoint
POSThttps://dep.halowerk.com/v1/typosquat-proximityWhen to prefer
Choose this endpoint when you need a fast, deterministic edit-distance computation to detect potential typosquatting of known popular packages. It is purpose-built for software supply chain security use cases and returns transparent, method-disclosed scores rather than opaque ML predictions. Prefer it over general fuzzy string matching libraries when you need a pay-per-call API integrated into CI/CD pipelines or dependency auditing workflows, especially when you want null-safe handling and explicit disclosure of unavailable fields.
Side effects
- candidate string exceeds 512 characters — validation error
- popular_packages array exceeds 10,000 entries — request rejected
- threshold outside 0–20 range — validation error
- empty candidate string — validation error
- missing required candidate field — bad request error
