A static JSON API serving enriched player metadata — names, birth dates, 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) and NFL (41 players, a seed cohort that is growing), both updated daily. NBA planned.
Registry provides four datasets per sport, 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 statusplayer_ids IDs + basic names (last, first, middle)
players_profile Adds full names and birth data
players_nfl_profile Adds position, position group, height, weight
players_nfl_roster Adds team, jersey number, 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 — MLB: prism_id, mlbam_id, bbref_id, fangraphs_ids, nfbc_id, sfbb_id, yahoo_id
NFL: prism_id, espn_id, fantasypros_id, fantasypros_slug, gsis_id, nffc_id, pfr_id, sleeper_id, sportradar_id, wikidata_id, yahoo_id
All players on a team:
https://registry.prism.statsvine.com/{sport}/{roster_product}/by_team/{pivot}/{team}.jsonAll players on a team, grouped by roster status:
https://registry.prism.statsvine.com/{sport}/{roster_product}/by_team_status/{pivot}/{team}.jsonRoster products are players_mlb_roster and players_nfl_roster — the only products carrying team and status.
Supported pivot values — MLB: abbrev (e.g. LAD), mlb_id (e.g. 119). NFL: abbrev only (e.g. DEN).
