QUESTIONS, ANSWERED STRAIGHT
Is this a picks service?
No. ONYX is research intelligence — every hitter graded with calibrated probabilities and the receipts published nightly. You see the same numbers we see, and you make the call.
What does "calibrated" actually mean?
When the model says 18%, hitters go deep about 18% of the time. The curve is fit to real graded outcomes (1,400+ hitter-games on the current version) and re-checked as every slate grades. The proof lives on the Results page — misses included.
Can I cancel anytime?
Yes. Monthly billing through Stripe, cancel in one click from your account page, access runs to the end of the period. No annual lock-in, no retention hoops.
Why is it $9.99 — what's the catch?
It's the founding rate. Early members lock it in while the record builds in public. The price rises as the product grows; founders keep theirs.
