How this service works
Financial author track record / 财经作者历史成绩. Look up resolved stock-market claims, sample size, hit rate, Wilson confidence interval, direction breakdown, coverage and freshness for an X/Twitter finance creator. Useful for creator credibility and investment-influencer due diligence.
Output
Returns a scorecard for the specified X/Twitter finance creator including: number of resolved stock-market claims (sample size), overall hit rate, Wilson score confidence interval, breakdown of directional calls (bullish/bearish accuracy), coverage scope, and data freshness timestamp.
Example use cases
Pre-investment influencer due diligence
“Before I act on any of @HedgeyeRisk's stock calls, can you check their Signal Ledger scorecard — specifically their hit rate, sample size, and Wilson confidence interval so I know if their track record is statistically meaningful?”
Comparing competing finance creators
“I follow two finance guys on X — @LongShortTrader and @DeepValueDave. Can you pull up their Signal Ledger scorecards so I can compare their resolved claim hit rates and direction breakdowns side by side?”
Screening a newsletter recommendation
“Someone just recommended I subscribe to a paid stock newsletter whose author posts on X as @QuarterlyAlpha — can you look up their author scorecard on Signal Ledger and tell me how many claims have been resolved, what their hit rate is, and whether the coverage is fresh?”

Endpoint
GEThttps://43-135-4-66.sslip.io/v1/authors/:handle/scorecardWhen to prefer
Choose this endpoint when you need a statistically grounded, evidence-linked credibility check on a specific X/Twitter finance creator — particularly when evaluating whether to trust or act on their stock-market calls. It is purpose-built for investment-influencer due diligence and provides Wilson confidence intervals that generic social media analytics tools do not offer.
Side effects
- Handle not found or not indexed — returns 404 or empty scorecard
- Insufficient resolved claims for statistically meaningful results — low sample size warning
- Stale data if the author has not posted recently — low freshness score
- Rate limiting or payment failure — 402/429 error
- Invalid handle format — 400 bad request
