Use Case Recommendations
Best for: FilingFirehose
FilingFirehose is a JSON API over SEC EDGAR built around one specific insight: filers routinely bury material events under 8-K Item 8.01 ('Other Events'), where item-code-based monitoring misses them. The company published an analysis of 4,251 filings finding that roughly 7% of Item 8.01 filings contain misclassified material events, and the product's core work is body-text classification of every 8-K so cyber incidents, officer departures and material agreements surface regardless of how the filer coded them. Coverage extends to S-3 and 424B5 shelf takedowns and Schedule 13D/13G filings, which together make it a dilution- and ownership-tracking tool as much as a news feed. Alongside the API sit consumer-priced one-time products: a $9 Mini-Report giving a three-section AI summary of a ticker delivered in about five minutes, and a $49 Full Report running five sections of AI analysis with twelve months of context, real-data citations on every claim and a full refund if the ticker has no data. That refund promise is a meaningful signal in a category where thin coverage is usually discovered after payment. The product ladder is unusually wide for an indie tool — eight products off one pipeline, aimed at retail traders, small funds, lawyers, security teams and developers — and there is a founder lifetime deal that collapses the whole stack into one payment.
Ideal use cases:
- •Teams or individuals who need body-text classification of every 8-k, independent of filer item coding
- •Teams or individuals who need s-3 / 424b5 shelf takedown and schedule 13d/13g coverage
- •Teams or individuals who need json api with full archive access and webhooks
- •Teams or individuals who need one-time ai forensic reports on any us ticker with source citations
- •Anyone focused on sec-filings workflows
- •Anyone focused on api workflows
Best for: VolRadar
VolRadar is a daily options-analytics service aimed narrowly at premium sellers — traders running covered calls, cash-secured puts, the wheel and credit spreads — rather than at directional traders. Its organising idea is a Weather Score that answers one question before anything else: are today's conditions worth selling premium into, or is it a day to wait. Beneath that sit IV-rank screeners across 500+ S&P 500 names, a covered-call screener, wheel and earnings screeners, an ETF screener, safe-to-sell lists and weekly idea sets, with strategy signals ranked and strikes computed rather than merely suggested. Earnings gates block setups where a print falls inside the holding window, which is the mechanical mistake that erases a quarter of premium income. The data comes from ORATS, an institutional options-data provider, and the methodology, data sources and even the research that did not work are published openly alongside an editorial policy and a glossary — an unusually legible posture for the category. A large free tier exists deliberately: the daily Weather Score, top five ranked candidates, a market brief and calculators, with strike-level detail, the full scanner and the daily model playbook behind the paid tiers. Ticker-level analysis pages exist for SPY, QQQ, TSLA, AAPL, NVDA, AMZN, META, AMD, MSFT, GOOG, IWM and COIN, covering IV, skew, walls, premium and expected-move accuracy.
Ideal use cases:
- •Teams or individuals who need weather score answers trade-or-wait before anything else
- •Teams or individuals who need iv-rank, covered-call, wheel and etf screeners on 500+ tickers
- •Teams or individuals who need computed strikes with p&l and breakevens on paid tiers
- •Teams or individuals who need earnings gates that block setups inside a print window
- •Anyone focused on options workflows
- •Anyone focused on trading workflows
