Sleeper API.
Sleeper Picks props, normalized.

Sleeper's public API covers its fantasy leagues, not the Picks pick'em board. KashRock ingests Sleeper Picks lines and serves them normalized — query GET /v6/esports/{sport}/props?book=sleeper with a free Sandbox key.

• —Player, stat type, line, direction, team, canonical propId.
• —CS2, Valorant, LoL, Dota 2, COD, R6, MLBB, Deadlock on one schema.
• —Same propId across Sleeper, PrizePicks, Underdog & Betr.

One key covers Sleeper and the other 24 books — every row comes back on the same schema, so nothing about the read is Sleeper-specific.

A real Sleeper row from production — the same shape every other book returns, with the canonical propId that lets you line-shop across venues.

• —The app's internal endpoints change without notice — the normalized schema does not
• —Player, stat, line, direction, and team arrive already mapped to canonical KashRock ids
• —The same propId lines Sleeper up next to every other book for comparison
• —One API key and one auth header replace per-source session handling

• —Create a free Sandbox key on Pricing — $0, no card, 500 requests every UTC day
• —Call GET /v6/esports/cs2/props?book=sleeper with the key in the X-API-Key header
• —Filter by stat_type, player, or match — the response is the board as KashRock serves it
