A static JSON API serving enriched player metadata — names, birth dates, MLB roster affiliations, and more — built on top of the stable identifier mappings from PRISM Crosswalk. Where Crosswalk gives you IDs, Registry gives you the context to use them.
Build artifacts (exports in multiple formats): statsvine/prism-registry
Part of the PRISM ecosystem for sports player identity and data.
Currently covers MLB (~1,700+ players who appeared on a 40-man roster in 2025 or 2026, updated daily). NFL and NBA planned.
Registry provides four datasets, each a superset of the previous:
player_ids IDs + basic names (last, first, middle)
players_profile Adds full names and birth data
players_mlb_profile Adds position, bat/throw hand, MLB debut date
players_mlb_roster Adds current team and roster statushttps://registry.prism.statsvine.com/{sport}/{product}/{prism_id}.jsonhttps://registry.prism.statsvine.com/{sport}/{product}/by_id/{source}/{source_id}.jsonSupported source values: mlbam_id, bbref_id, fangraphs_ids, nfbc_id, sfbb_id, yahoo_id
All players on a team:
