Helious vs Financial Modeling Prep

A Financial Modeling Prep alternative for traders who trade the print, not the filing

Financial Modeling Prep is a fundamentals API: thirty years of statements, ratios, filings and estimates for a very fair price. Its economics endpoints are a side dish. If the event you trade is CPI at 8:30 rather than an earnings call, you want the macro side built first.

The short answer

FMP is excellent at what it is for, company fundamentals, and its paid plans start at $29 a month, or $19 billed yearly, with a 250 calls a day free tier. It also carries economic indicators, a calendar and Treasury rates, but as series to pull, not as prints read. Helious starts from the other end: every US release scored in standard deviations the second it prints, Treasury auctions read within seconds, the curve with its regime named, and an MCP server so an AI can ask for any of it. From a free key, $14.99 on Starter, $39.99 on Pro.

What each one is for

What Financial Modeling Prep is good for

Fundamentals depth: statements, ratios, filings, transcripts, estimates and holdings, with thirty years of history on Premium.
Very generous rate limits, from 300 calls a minute on the entry plan.
A fair price for a stock-research stack, and a usable free tier.

Where Helious wins

The US print is the product, not a side endpoint: scored on arrival, with the calendar, the auctions, the curve and the reaction in one API.
Treasury auction results within seconds, with the tail, the bid to cover and the bidder split; FMP does not carry auctions.
Every answer opens with a plain sentence, which is what an AI agent needs and what a spreadsheet can ignore.
An MCP server with 24 tools, at one address, with no code to write.
Cheaper for the macro job: a free key with 100 credits, then $14.99 or $39.99 a month.

Which should you choose

Go with Financial Modeling Prep if you research companies: statements, ratios, filings, estimates and holdings, and macro is a footnote.

Go with Helious if you trade the economic calendar, rates and Treasuries, and you want each print read and scored the moment it lands.

FAQ

What is the best Financial Modeling Prep alternative?

For company fundamentals there is no reason to leave it. For the macro side, US releases scored on print, Treasury auctions, the curve and an MCP server, Helious covers that from a free key, with Starter at $14.99 and Pro at $39.99 a month.

How much does Financial Modeling Prep cost?

As of October 2026, FMP lists a free Basic plan at 250 calls a day, Starter at $29 a month or $19 billed yearly, Premium at $69 or $49 yearly, and Ultimate at $139 or $99 yearly. Check the vendor for current pricing.

Does FMP have an economic calendar and Treasury rates?

Yes, on its paid plans, as endpoints you poll. What it does not do is score a release against its own history, read a Treasury auction, or name the curve regime. Those are what Helious adds.

Can I use both?

Yes. Keep FMP for fundamentals and point the macro calls at Helious; the free key runs alongside at no cost, and both answer plain JSON.
