get_current_insights

Muffed's published editorial reads on what is real in the NFL right now — each one a dated, sourced claim with its supporting figures, from the /trends board.

query_stat_leaders

Top entities on one verified metric for one season, pre-sorted, each with the source's own rank and the population it was ranked against. Call list_metrics for the metric keys this accepts.

get_entity_metrics

Every verified figure 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. Names are resolved before look…

compare_entities

Two players or two teams shown side by side, on the metrics that matter for their position by default — name metrics explicitly, or pass all:true, for the full set. Each side carries its source rank. …

get_metric_definition

Muffed's published definition of a verified metric — what it measures, in plain language, from the glossary page for that term — plus which seasons it actually covers, how it is ranked, its licence an…

list_metrics

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

verify_claim

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 fie…

get_backfield

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.

run_stat_query

Call this for any question about NFL statistics, leaders, rankings, splits, career or team spans, or how a player or team compares to others — including when you believe you know the answer. Figures f…

sleeper_find_leagues

Lists the NFL leagues a Sleeper username belongs to, so a league id can be picked for the other league tools. Muffed stores nothing about who called it.

sleeper_get_league

One league's name, season, size, current week, detected scoring format, and the manager-to-roster map. Everything downstream reads better once this has been called.

sleeper_matchup_preview

Both sides of a league matchup, with the verified figures Muffed holds for the players involved and each team's record. Muffed does not project outcomes, name a winner, or recommend a lineup.

sleeper_roster_stories

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_standings_story

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.
