How this service works
24/7 price monitoring for crypto, stocks, and forex. Get pinged the second your buy or profit target is reached. Track real P&L in pesos.
Output
Returns a JSON object with aggregate stats: total signals, graded count, pending count, confidence buckets with hit rate and CI bounds, per-symbol breakdowns (symbol, correct, samples, hitRatePct), per-verdict breakdowns (verdict, correct, samples, hitRatePct, avgReturnPct), overall Brier score, and independent sample count.
Example use cases
Auditing alert service before subscribing
“Before I set up price alerts with NythosX, can you check their historical track record? I want to know their overall hit rate, Brier score, and how their buy signals have performed on average.”
Evaluating MSFT signal accuracy
“How well has NythosX done at calling Microsoft price targets? Pull their track record and show me MSFT's hit rate and how many samples they have graded.”
Comparing signal confidence tiers
“I want to see how NythosX's medium-confidence signals have performed historically — what's the hit rate and confidence interval for that bucket?”
Technical details
Endpoint
GEThttps://market.nythosx.com/api/v1/track-record?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to audit or validate the historical accuracy of NythosX price alerts before relying on them for trading decisions, or when benchmarking signal quality using calibration metrics like Brier score and confidence-stratified hit rates. Prefer this over simply trusting marketing claims when evaluating a price-alert provider.
Side effects
- No data available yet — track record may return empty buckets or zero graded signals if the service is newly launched
- API returns stale data if grading pipeline is delayed
- Payment failure (insufficient USDC balance) prevents access
- Rate limiting if called too frequently
- Partial data — some symbols or verdicts may have too few samples for meaningful confidence intervals
