Edgrapi vs WhaleWisdom
WhaleWisdom is a deep 13F research platform: over 20 years of hedge-fund holdings, a backtester, and a UI built to replicate a fund. Edgrapi is a broad SEC EDGAR developer API that returns 13F as parsed JSON, alongside fundamentals, insider trades, and 8-Ks.
WhaleWisdom is a 13F specialist, and a good one. It tracks institutional holdings from 13F, 13D and 13G filings back to Q1 2001, with a backtester that shows what copying a fund's top holdings would have returned, a Duplicator that clones a portfolio, stock screeners, heat maps, and an Excel add-in. If your job is researching or backtesting hedge-fund portfolios, it is purpose-built for exactly that.
Edgrapi is a broader tool aimed at developers. It reads the same SEC EDGAR filings and returns 13F holdings as parsed JSON, but alongside parsed fundamentals, insider Form 4 trades, 8-K events, and 13D/13G stakes, over a REST API and an MCP server you call from any language or an AI agent. The trade is depth in one filing type versus breadth across many, delivered as data rather than a research UI.

Which should you use?
Use WhaleWisdom if you are an investor researching hedge funds: its 20-plus years of 13F history, backtester, and portfolio tools go deeper on institutional holdings than Edgrapi does, and the UI is built for that work. Choose Edgrapi if you are a developer or building an AI agent that needs SEC data as JSON: it returns 13F alongside fundamentals, insider trades, 8-Ks and activist stakes, from any language, over REST or MCP, with a free tier. WhaleWisdom is a 13F research platform; Edgrapi is a broad SEC data API. They overlap only on 13F, and there WhaleWisdom is the deeper of the two.
Frequently asked questions
Is WhaleWisdom free, or do you have to pay?
WhaleWisdom has a free tier with the last two years of 13F history and most of its tools; paid plans, roughly $300 to $500 a year, unlock full history back to 2001 plus WhaleIndex and fund WhaleScores. Edgrapi also has a free tier, 100 credits a month with no card, and those credits call the API directly, so you can build on the free tier rather than only browse a UI.
How current is WhaleWisdom's data?
13F holdings are quarterly and filed up to 45 days after the quarter ends, so neither WhaleWisdom nor any other 13F source shows live positions; both read a delayed snapshot. For near-real-time SEC signals you need different filings: Edgrapi returns insider Form 4 trades and 8-K events within a couple of minutes through webhooks, which WhaleWisdom does not cover.
Does WhaleWisdom have an API?
Yes. WhaleWisdom's API exposes its 13F database, holdings, holders, comparisons and bulk export, optionally including 13D and 13G data, at 20 requests per minute, with full history behind a paid subscription. It does not cover fundamentals, insider Form 4, or 8-K filings. Edgrapi returns all of those as parsed JSON, with a free tier and higher programmatic limits.
What does Edgrapi cover that WhaleWisdom doesn't?
WhaleWisdom covers 13F and 13D/13G only. Edgrapi covers those plus parsed fundamentals (income statement, balance sheet, cash flow), insider Form 4 trades, and 8-K material events, all as JSON over REST and MCP. WhaleWisdom covers 13F far more deeply; Edgrapi covers more of SEC EDGAR.
