The source stack is deliberately small, attributable, and cheap to serve. New feeds only land when their rights, identifiers, and update paths are clear.
Composite market values, ranks, attributed history when supplied, season results, advanced usage, consistency, and similar-market tiers. A scheduled publisher validates the licensed feed and packages the current release with the app.
Read official API docs ↗All 32 teams, the complete current schedule, venues, rest, surfaces, and prior-season scoring results. FTT records source hashes and derives the visible matchup-temperature model under CC BY 4.0 attribution.
Inspect the data project ↗Raw totals, roster-cost weights, verdict thresholds, share URLs, and balancing suggestions execute locally and deterministically. They do not require a model call or third-party trade-evaluation request.
Inspect the formula →Player pages and trade tools use Wikimedia API-selected images with reviewed Creative Commons terms. Every image record retains its creator, source file, and license; full credits appear on player profiles and trade receipts. Sleeper and ESPN image hotlinks are not used.
Visit Commons ↗Player values and ranks are captured throughout the day, versioned, and retained for market movement, downloadable records, and long-term research.
The latest validated market variants, player profiles, and compact profile histories live in the versioned public release used by every server-rendered page and calculator.
Timestamped value, overall rank, position rank, and release ID observations are retained chronologically and exposed through player and market downloads.
Complete market and pick variants are stored as compressed, append-only snapshots in the private build repository. Raw archives are not shipped in the production container and can move to immutable object storage without changing public URLs.
Scoring, roster slots, taxi, IR, picks, standings, and manager-specific needs.
FTT-owned comparisons between market movement, opportunity, usage, and production.
Injuries, practice reports, transactions, depth charts, and verified news.
An anonymized, rights-reviewed corpus of completed prices by format and league size.
