Base URLhttps:
- GET/report$0.35The whole week in one briefing: players emerging before consensus, injury fallout and handcuffs, stock up and down, rookies and streamers. **Use when** an agent needs broad weekly context rather than an answer about a particular player or team. The widest and most expensive league-wide read.
- GET/sleepers$0.2Eight to twelve low-rostered players to start this week, with snap share, target share, red-zone work and the matchup behind each. **Use when** an agent needs lineup options the market has not priced in yet. Weekly and league-wide; for one named player use /v1/player.
- GET/waivers$0.2Ranked waiver-wire targets with a suggested FAB bid and a stash-or-start label on each. **Use when** an agent is asked who to claim this week and how much to spend. League-wide; for adds available in one specific league use /v1/roster.
- GET/trending$0.1Top 25 Sleeper trending adds and drops, each with the usage numbers behind the move and an add/fade/hold verdict. **Use when** an agent needs to know who fantasy managers are picking up right now and whether the crowd is right. Covers the whole league, not one team.
- GET/draft-board$0.2A tiered board of 200 players ranked against where the market drafts them, with prior-season usage behind every ranking and the values and reaches called out. **Use when** an agent is preparing for or sitting in a fantasy draft. Season-scoped, not weekly. Ranks against Sleeper draft popularity, which is a market signal and not a consensus ADP.
