EdgarKit vs Financial Modeling Prep

Financial Modeling Prep is a broad financial data platform that covers SEC filings as one of many endpoints. EdgarKit is a specialized SEC EDGAR API. They overlap in the middle but solve different problem shapes.

The short answer

FMP is the right choice when you need SEC data plus equity prices, fundamentals, financial ratios, economic data, forex, crypto, and many other endpoints from a single subscription. The SEC coverage is part of a much larger menu.

EdgarKit is the right choice when SEC filings are the actual product you're building on. Better latency on insider trades and 8-K, real-time webhooks, deeper form coverage on the SEC-specific side, and a simpler price structure for the SEC use case.

Side-by-side

| | FMP | EdgarKit | |---|---|---| | Primary focus | All-in-one financial data | SEC EDGAR specialist | | SEC form coverage | Form 4, 13F, 8-K (limited), 10-K, 10-Q | All major forms (3, 4, 5, 13F, 13D/G, 8-K, 10-K, 10-Q, S-1, DEF 14A, 144) | | Real-time filings | Hourly to daily on most endpoints | ~30 seconds via API and webhook | | Webhooks | Limited / not core | Yes, on paid tiers | | Insider trades latency | Several hours typically | ~30 seconds | | Other data | Equity prices, fundamentals, FX, crypto, economic | None, SEC only | | Pricing model | $19+/mo for basic, scales by request volume | Free tier + $19/$79 | | Free tier limits | 250 requests/day historically | 1,000 requests/month | | CUSIP to ticker | Yes, included | Yes, included | | Footnote text on Form 4 | Often missing | Always included |

When FMP is the right choice

  • You're building a broad fintech product that also needs equity prices, fundamentals, FX, and economic data alongside SEC filings.
  • You're price-sensitive on the broader data bundle and the SEC piece is a secondary use case.
  • Daily-batched insider trade data is good enough for your strategy.
  • You want one vendor invoice instead of separate subscriptions.

FMP's value is breadth. If you need to wire up a dashboard with stock charts, P&L tables, valuation ratios, and insider activity from one provider, the all-in-one price math works.

When EdgarKit is the right choice

  • Your product is centered on SEC filings as the differentiator, not the bundle.
  • You need real-time delivery (Form 4 cluster alerts, 8-K event detection, S-1 IPO monitoring).
  • You hit FMP's daily request cap and need a higher SEC-specific allowance.
  • You want webhook push instead of polling.
  • You need form types FMP doesn't cover in depth (Form 3, Form 5, Form 144, 13D/G activist filings, DEF 14A proxies).

The latency gap on insider trades

FMP's /v3/insider-trading endpoint returns recent Form 4 data, but the data is typically refreshed on an hourly to daily cadence. For research and dashboards this is fine. For real-time event-driven strategies, the lag costs you.

EdgarKit ingests Form 4 filings within roughly 30 seconds of SEC acceptance and pushes them via webhook to your endpoint, or makes them queryable via the API on the same timeline. For traders running Form 4 P-code alerts, the difference between hourly-batched and 30-second push is the difference between catching the post-filing drift and missing it.

Form coverage gaps

FMP's SEC coverage is solid on Form 4, 10-K, and 10-Q. It's lighter on:

  • Form 3 and Form 5, present but not as cleanly indexed.
  • Form 144, pre-sale notices, often missing or partial.
  • 13D/G activist filings, covered but without amendment-tracking precision.
  • DEF 14A proxy statements, listed but without parsed compensation tables.
  • 8-K item-level filtering, you get the filing but item-code filtering takes additional work.

EdgarKit covers all of these as first-class form types with consistent filter parameters. See the SEC filing types list for the full enumeration.

Pricing math for SEC-only workloads

FMP's pricing is built around bundle value. If you're only consuming the SEC-related endpoints, the math gets unfavorable as your volume grows. EdgarKit's free tier (1,000 requests/month) is enough to prototype most strategies, and the $19/mo Basic tier covers most production use cases for a single product.

A rough heuristic: if more than 60% of your data needs are SEC-specific, EdgarKit is usually cheaper. If more than 60% are non-SEC (prices, fundamentals, etc.), FMP's bundle wins.

Using them together

It's reasonable to subscribe to both. FMP for the broad price + fundamental data, EdgarKit specifically for the real-time filing layer. Many production teams end up doing this because no single provider is optimal across all data domains.

FAQ

Does FMP have webhooks?

Limited. FMP is built around REST polling. Real-time push for SEC filings is not a core part of the FMP offering. EdgarKit's webhook system is purpose-built for that.

Can I get historical Form 4 data from FMP?

Yes, FMP exposes Form 4 history via the insider-trading endpoint. EdgarKit also exposes historical Form 4 back to 2003. Both will work for backtesting; the practical differences are at the real-time edge, not the historical archive.

Is FMP free?

FMP has a free tier (around 250 requests per day, varies). EdgarKit's free tier is 1,000 requests per month. The shape is different, FMP rewards bursty daily polling, EdgarKit rewards efficient monthly usage with webhook push.

Which has lower insider-trade latency?

EdgarKit. Form 4 filings are available within ~30 seconds of SEC acceptance versus the hourly-to-daily refresh on FMP's insider-trading endpoint.

Do I need both?

Only if your product needs both broad financial data (prices, fundamentals, FX) and real-time SEC filings. For SEC-centric products, EdgarKit alone covers it. For broad fintech products, FMP alone covers it. For products where SEC is the differentiator but you also need supplementary price data, both make sense.
