Muffed

One league's name, season, size, current week, detected scoring format, and the manager-to-roster map.

sleeper_get_league

League standings derived from Sleeper's roster settings — records, points for, and points against where available. Sleeper publishes no standings endpoint, so these are computed from the roster rows.

sleeper_standings_story

The verified figures Muffed holds for one NFL player or one NFL team (by name or abbreviation, e.g. "Bijan Robinson" or "DEN"), with the source's rank where one exists. By default the headline figures for that player or team; scope "all" returns every figure held, and a named metric returns all of that metric's rows. Names are resolved against the players and teams Muffed holds; an unrecognised name returns the closest matches rather than a guess.

get_entity_metrics

One team's roster mapped to the verified figures and published Muffed surfaces for each player. Players Muffed does not cover are listed as uncovered rather than omitted.

sleeper_roster_stories

Muffed's published handcuff page for one team's backfield, plus the current depth chart and injury status from Sleeper. Answers who backs up a starter, and who replaces one who is out.

get_backfield

Checks structured claims against Muffed's verified panel. Each claim comes back confirmed, wrong (with the actual value), or unverifiable (with the metric's real season coverage). Takes structured fields only, not sentences.

verify_claim

Two players or two teams shown side by side — by default on the metrics that matter for their position, on named metrics when `metrics` is set, and on the full set with all:true. Each side carries its source rank. States both figures and stops: it names no winner, no margin and no recommendation. `metrics` takes verified panel metric keys ("qb_anya.any_a") or their plain-English names. A measure outside the verified panel, such as yards per attempt, is refused with the nearest panel metrics.

compare_entities

Computes an NFL figure from a structured query rather than looking one up: a population (position, qualifying threshold), a window (seasons, weeks, a team span, a coach's tenure), one named measure, and one operation (leaders, rank, count, only-who, a per-season streak, or a share of a total). Answers questions the verified panel has no pre-computed row for — qualified superlatives, multi-season streaks, derived rates. Every response carries the executed method, the population size, the measure's definition and the data version it ran against. Figures are computed on request from nflverse data and are labelled as computed, not verified. A figure that cannot be served comes back with the reason and the nearest thing covered. Fantasy measures answer in the convention `scoring` names — "standard", "half_ppr" or "ppr" — and default to half-PPR when none is named; the response says which it used. A bare "PPR" means full PPR. measure.key takes a measure name ("rushing_yards", "half_ppr_points") or a verified panel metric key ("key_player_stats.rushing.yards", "fantasy_scoring.half_ppr_points"). A panel metric key this tool does not compute is refused with the reason.

run_stat_query

Lists the NFL leagues a Sleeper username belongs to, with each league's id. Muffed stores nothing about the requester.

sleeper_find_leagues

What Muffed can answer on. By default a summary of metric families with their counts and season coverage; with search or detail:true, individual metric keys. Returns keys and coverage only, never figures.
