FlashSEC is an SEC filing research platform with dilution and share-structure tools, filing alerts, and JSON API access. If you are comparing FlashSEC, Dilution Tracker, and AskEdgar, start with the workflow you need: researching a ticker in an app or bringing dilution data into your own scanner, dashboard, or AI tool.
This review covers FlashSEC’s publicly described features and pricing, then explains how to evaluate AskEdgar for small-cap and nano-cap research. It is published by AskEdgar; FlashSEC information was checked against its public website on October 18, 2026. The comparison is based on published information, rather than a hands-on benchmark of FlashSEC’s API.

What does FlashSEC offer?
FlashSEC’s website describes four core features:
- Company research: tables covering dilution activity, share offerings, share structure, and cash status.
- Filing monitoring: a live feed of new filings and email alerts for watchlist companies.
- Education: explanations of filing and dilution terminology.
- API access: programmatic JSON data for analysis workflows and trading algorithms.
These are relevant capabilities for traders who want filing information organized around a company. Developers should also check the actual response fields and access terms for the workflow they plan to build.
Does FlashSEC have an API, and what does it cost?
Yes. FlashSEC advertises JSON API access, and its official FAQ directs API access requests to support@flash-sec.com. That page lists subscriptions at $49.99 per month or $499 per year, with API included in the feature lists. Institutional pricing is listed separately.
Confirm current pricing, endpoint availability, usage limits, and any commercial-use requirements with FlashSEC before integrating. A subscription feature list is not a substitute for checking the API contract your application will depend on.
How AskEdgar fits a small-cap research workflow
AskEdgar provides an app for traders and structured datasets for developers. For a small-cap dashboard, the useful questions are specific: what securities could add shares, can the company raise money through a registered offering, how much capacity remains, and how does that compare with its float and financing history?
- Warrants and convertibles: inspect remaining warrant amounts, exercise prices, convertible note balances, convertible preferred securities, conversion prices, and price-protection labels. The dilution data API reference documents the fields. Use maintained remaining amounts when assessing current exposure, rather than assuming the original issuance is still outstanding.
- Shelf and ATM capacity: monitor registrations and financing capacity through the SEC Registrations API. Keep an available registration, remaining capacity, and an announced financing distinct. Capacity describes a company’s ability to raise capital; it does not establish that an offering is imminent.
- Audited float and share structure: use AskEdgar’s maintained float data in a scanner or research screen. Public float and tradable float are different measures. That distinction matters both for trading research and for interpreting baby-shelf capacity.
- Offering risk and cash runway: combine financing history and offering ability with estimated cash runway using the Dilution Rating API. AskEdgar’s cash estimate accounts for reported cash, estimated burn since the reporting date, and interim capital raises. Financing history matters even when a company does not appear to need cash immediately.

Searching for a “dilution tracker API”?
That phrase can mean API access to the specific DilutionTracker service, or any API that helps you track stock dilution. FlashSEC, DilutionTracker, and AskEdgar are separate services. AskEdgar’s API provides AskEdgar datasets; it is not an API wrapper for either competitor.
If your goal is to build a dilution tracker, evaluate providers against the fields your tool needs. For a product-level comparison of the named service, read Dilution Tracker vs AskEdgar for traders and builders.
Four checks before choosing a dilution data API
- Check the current records. Pick a ticker you know and inspect what happens after exercises, conversions, repricings, or a financing. Original deal terms alone may not describe the current exposure.
- Check definitions and units. Warrant counts are shares; a convertible debt balance is dollars. Public float is not the same as tradable float. Shelf, baby-shelf, and ATM limits may overlap, so do not add them together as independent pools.
- Check the full workflow. Test authentication, pagination, missing values, and the response fields you need before building your whole application around a provider.
- Check access and cost. Confirm usage pricing and licensing for your intended use, especially if customers will see the data. Separate a personal research tool from redistribution in a commercial product.
Start building with AskEdgar
A focused first project is a watchlist that puts offering risk beside warrant and convertible exposure. Start with one ticker, inspect the returned records, then expand to the rest of your watchlist.
- Follow the AskEdgar API Quickstart to set up access and make your first request.
- Review the documented dilution-rating and dilution-data responses before deciding which fields your screen should display.
- Use the API pricing calculator and the Quickstart’s cost-estimation instructions before scaling up.
