Why PlayCaller Data

Six things the data does that others don't.

Most sports data APIs give you numbers. PlayCaller gives you intelligence — signals extracted, resolved, and scored before they reach aggregators.

Anomaly Detection

3-season usage baseline per player

Every player has a normalized usage fingerprint across snap share, target rate, and touch volume. Deviations >15% from the rolling baseline flag as anomalies. Surfaced via signal_type=anomaly in the intelligence feed.

Signal Cadence

625 signals refreshed every 2 hours

Beat reporter signals from ESPN NFL, MLB, and NBA injury feeds are scraped and classified on a 120-minute cycle. High-severity signals trigger out-of-band pushes. scraped_at timestamp in every response so you know the data age.

Cross-Platform Resolution

One canonical ID across 6 platforms

13,606 player identities normalized across ESPN, Sleeper, Yahoo, NFL.com, Rotowire, and BallDontLie. Query by playcaller_id — it resolves correctly regardless of which platform your user came from.

Confidence Scoring

AI confidence on every prop signal

Prediction market signals include a confidence_score field (0–100) representing AI-weighted probability derived from the beat reporter feed, usage trends, and historical accuracy. Kalshi-sourced market odds provided alongside for comparison.

Intercorrelation

Cascade signals, not isolated events

A QB injury doesn't just flag the QB — it triggers correlated signals for every receiver on the depth chart, the backup QB's usage projection, and relevant waiver wire targets. Each signal includes a correlated_player_ids array.

Latency

Sub-200ms p95 on intelligence endpoints

Intelligence feed responses are served from in-memory cache with a 15-minute TTL. Cold-path DB queries hit a Neon Postgres pool with connection pooling. Rate limits: Hobbyist 30 req/min, Pro 150 req/min, Enterprise negotiated.

What You Get

We process beat reporter feeds, verified sources, and on-field observations so you don't have to. Clean JSON. Low latency. Real data.
