Api Endpoint

bio.halowerk.com

Builds amino-acid k-mer sets, calculates Jaccard similarity, and finds the highest contiguous identity between each supplied epitope and any equal-length window of the query. It does not predict immune binding, allergenicity, cross-reactivity or clinical risk and cannot replace curated databases or laboratory testing.
