Henshin ingests from hundreds of sources across dozens of verticals, resolves every entity into a canonical record, and streams it back through one API. Pricing, inventory, competitors, movement — in one feed.
Structured records with canonical taxonomies, entity resolution, and historical series — exposed through a single, predictable API.
Every record mapped to one taxonomy, deduped across sources, and resolved to a single canonical entity.
GTIN and name-brand matching link the same product across retailers into a single canonical group.
Track every price move, markdown, and restock with a complete historical series per record.
Versioned REST plus typed SDKs, webhooks for price, stock and new-arrival events, and bulk CSV / Parquet.
Start with commerce — our flagship vertical with 312 retailers across the world. Add real-estate listings, cloud pricing, finance signals, grocery, or automotive. One API, one schema, one bill.
Thoughtfully versioned REST endpoints, typed SDKs for Node, Python, Ruby and Go, and a playground that mirrors production. Pagination, filtering, and sorting work exactly the way you would expect them to.
