# One call. Live NFL intelligence. curl https://playcallerapp.com/v1/intelligence/news?player=AJ_Brown&limit=1 -H "X-PlayCaller-Key: pc_live_your_key"
Every other sports data API sells you numbers. Sportradar at $1,400/month. SportsData.io at $5,000/month. Raw stats, scores, box scores. You build the intelligence yourself.
PlayCaller ships the intelligence pre-assembled.
The GET /v1/feed endpoint returns a complete player intelligence dossier in a single API call: a calibrated confidence score backed by a logistic regression model trained on 20,585 observations across 5 NFL seasons (AUC-ROC 0.697, 4.61x decile lift), a validated heat signal identifying players whose opportunity metrics are converging before the market prices it in (6pp quartile lift, validated directional model), a full signal breakdown showing exactly what drove each score, and a plain-English synthesis sentence generated from the signal data and validated against the source before delivery.
No heuristics. No black boxes. Every claim traces to a measured model.
No credit card. 14-day Developer Sandbox starts immediately.
Activation link in inbox. Key generated instantly in pc_live_xxxx format.
One GET request, one header. Live NFL intelligence in milliseconds.
