In May I posted the self-hosted version of the pipeline here. This is the hosted one, which now also covers non-US stocks and is built to be used by AI agents (over MCP) as well as by code (REST).<\/p>\n<p>What&#8217;s in it:<\/p>\n<ul>\n<li>SEC filings, full text (10-K, 10-Q, 8-K, proxies). You can search inside a filing and pull the exact lines, not just metadata<\/li>\n<li>financial statements and KPIs as reported, each tagged with fiscal period and filing date<\/li>\n<li>earnings call transcripts, by speaker<\/li>\n<li>13F institutional holdings: holders of a stock, or a manager&#8217;s full portfolio<\/li>\n<li>insider transactions (Forms 4 and 5) and congressional trades (House and Senate)<\/li>\n<li>short interest, daily short volume, fails to deliver, off-exchange volume, a squeeze score, and a model estimate of the next FINRA short interest<\/li>\n<li>executive compensation, government contracts, buybacks, going-concern flags, IPO filings<\/li>\n<li>prices for US, European, UK, Hong Kong and Chinese listings (end of day on the free plan), option chains on paid plans<\/li>\n<li>Fed economic series and CFTC data<\/li>\n<\/ul>\n<p>How to get at it:<\/p>\n<ul>\n<li>MCP, for AI agents: <code>https:\/\/mcp.equibles.com\/mcp<\/code> (Claude, ChatGPT, Cursor and others)<\/li>\n<li>REST: <a href=\"https:\/\/equibles.com\/docs\/api\">https:\/\/equibles.com\/docs\/api<\/a><\/li>\n<li>free plan: 100 requests a day across both, no card. Plus is $9.99 a month for 10,000 a day. Pro adds bulk CSV downloads (short interest, short volume, FTD, buybacks and a few more, one file per year)<\/li>\n<li>self-host: the open source core (AGPL-3.0) pulls the SEC data itself: <a href=\"https:\/\/github.com\/daniel3303\/Equibles\">https:\/\/github.com\/daniel3303\/Equibles<\/a><\/li>\n<\/ul>\n<p>One detail for the backtesting crowd: short interest bulk rows carry FINRA&#8217;s publication date, so you only use numbers that were public at the time.<\/p>\n<p>Why &#8220;Financial Datasets alternative&#8221; in the title: it&#8217;s the name I see most for financial data APIs aimed at AI agents. From their pricing page they don&#8217;t have a free tier, and transcripts, congressional trades and short interest aren&#8217;t on their list. If I&#8217;ve got that wrong, correct me and I&#8217;ll fix the post.<\/p>\n<p>So that&#8217;s the pitch, a free financial data API for AI agents and the humans who build them. What would make it more useful as a dataset source for you: bulk files for more datasets, point-in-time snapshots, something else?<\/p>\n<\/div>\n<p><!-- SC_ON -->   submitted by   <a href=\"https:\/\/www.reddit.com\/user\/DanielAPO\"> \/u\/DanielAPO <\/a> <br \/> <span><a href=\"https:\/\/www.reddit.com\/r\/datasets\/comments\/1x8mbyt\/selfpromotion_free_financial_data_api_for_ai\/\">[link]<\/a><\/span>   <span><a href=\"https:\/\/www.reddit.com\/r\/datasets\/comments\/1x8mbyt\/selfpromotion_free_financial_data_api_for_ai\/\">[comments]<\/a><\/span><\/p><div class='watch-action'><div class='watch-position align-right'><div class='action-like'><a class='lbg-style1 like-42954 jlk' href='javascript:void(0)' data-task='like' data-post_id='42954' data-nonce='8bd368e94e' rel='nofollow'><img class='wti-pixel' src='https:\/\/www.graviton.at\/letterswaplibrary\/wp-content\/plugins\/wti-like-post\/images\/pixel.gif' title='Like' \/><span class='lc-42954 lc'>0<\/span><\/a><\/div><\/div> <div class='status-42954 status align-right'><\/div><\/div><div class='wti-clear'><\/div>","protected":false},"excerpt":{"rendered":"<p>Disclosure: I run this, it&#8217;s Equibles.
