FMP SDK

The idea behind this project is to provide a 'one-stop-shop' to the API endpoints provided by Financial Modeling Prep (FMP).

A personal note to you: my apologies for letting this package get so out of date. FMP kept reshuffling its API, then I had a personal issue delay me further. Things are back on track now. Because of that gap, roughly half of this package's old methods had gone defunct against FMP's current API, so rather than patch around that I rebuilt it from scratch against FMP's stable/ API. If you're on 20250102.0 or earlier you're on the old, pre-rewrite methods; anything newer uses the schema described below. Old releases are yanked from PyPI (a plain pip install fmpsdk now always gets the rewrite), but still installable if you pin one explicitly, e.g. pip install fmpsdk==20250102.0 — note that won't actually restore functionality, though: FMP sunset the legacy /api/v3/ API those old methods called entirely on 2025-08-31, so a pinned old version installs fine but its calls will fail regardless. It's there for compatibility with existing pinned requirements files while you migrate, not as a way to keep avoiding the rewrite.

What's covered

29 data groups, ~240 methods total, each reachable both as client.<method>(...) and grouped under a matching namespace, e.g. client.statements.income_statement(...):

Company & fundamentals — profile, executives, M&A, DCF valuation, financial statements/ ratios/growth (income, balance sheet, cash flow — as-reported, TTM, and growth variants)
Market data — real-time & aftermarket quotes, historical price charts, technical indicators
Reference & screening — symbol/CIK/CUSIP/ISIN search, the company screener, sector/ industry/exchange directories
Calendars & events — earnings, dividends, splits, IPOs, the economic calendar
Ownership & compliance — insider trades, Form 13F institutional ownership, SEC filings, ESG disclosures
Alternative markets — crypto, forex, commodities, indexes, ETFs & mutual funds
Sentiment & analysis — analyst grades/price targets, TipRanks ratings, congressional trading, market movers
Bulk downloads — whole-universe data dumps, one call instead of one per symbol

Every method's own docstring says which FMP plan tier it needs (Free/Starter/Premium/ Ultimate) — see Pricing tiers below. One exception: the 7 client.tipranks methods are implemented and unit-tested but untested against a real response — see that section for why.

How to Use

Requires Python 3.9+. Install the package: pip install fmpsdk python-dotenv (python-dotenv is optional — it's just how the example below loads your API key from a .env file).
Create a .env file and put your API key in it. Inside .env: FMP_API_KEY='blah'
Build a Client and call methods on it, grouped by data category — e.g. client.company.profile(symbol="AAPL"), client.statements.income_statement(symbol="AAPL").
The return from a method call is almost always a list of dictionaries. It is up to you to parse it.

Example code

server.ts

#!/usr/bin/env python3

from dotenv import load_dotenv

import fmpsdk

# Actual API key is stored in a .env file. Not good to store API key directly in script.
load_dotenv()
client = fmpsdk.Client()  # reads FMP_API_KEY from the environment

# Company Valuation Methods
symbol = "AAPL"
print(f"Company Profile: {client.company.profile(symbol=symbol)}")

# Every non-2xx FMP response raises a typed exception instead of returning
# None or an error-shaped dict, so a plan-gated or bad-key call is obvious:
try:
    client.statements.income_statement_ttm(symbol=symbol)
except fmpsdk.FMPPlanLimitError:
    print("Your FMP plan doesn't cover this endpoint — check its docstring for which tier does.")
except fmpsdk.FMPAuthenticationError:
    print("Check your FMP_API_KEY.")

One naming quirk worth knowing up front: client.quote is the namespace for the whole quote group (client.quote.aftermarket_quote(...), client.quote.batch_quote(...), etc.), so it shadows the top-level quote() method of the same name — call that one as client.quote.quote(symbol="AAPL").

Pricing tiers

FMP's plans form a ladder — Free, Starter, Premium, Ultimate — and each one adds more endpoints on top of the last. A call your plan doesn't cover raises fmpsdk.FMPPlanLimitError rather than returning data. There's no single tier table to keep in sync here — instead, every group module's docstring (e.g. fmpsdk/endpoints/search.py) and every method's own docstring says plainly which tier it needs, right next to the code that calls it, verified live against a real key at every tier from Free through Ultimate. Check those, or just try the call and catch FMPPlanLimitError.

One exception, outside that ladder entirely: client.tipranks's 7 methods. They still 402 even on Ultimate — FMP's own error message says why: TipRanks data needs a separate paid add-on ("TipRanks data boost"), bought independently of the four plan tiers above. We haven't purchased it, so these 7 methods are implemented and unit-tested (mocked) but never verified against a real response — treat them as unverified rather than confirmed-working. If you have that add-on and hit a bug in one of them, a PR with the fix (and what the real response actually looks like) is welcome.

MCP server & OpenAPI spec

mcp/ — a Model Context Protocol server, published separately as fmpsdk-mcp (so pip install fmpsdk never pulls in fastmcp). Lets an AI assistant (Claude Code, Claude Desktop, …) query FMP through this library: 10 curated tools for the common asks (quotes, profiles, statements, ratios, price history, news) plus discovery tools that reach all ~240 methods at runtime. With uv:

Terminal

claude mcp add fmpsdk -s user -e FMP_API_KEY=your-key -- uvx fmpsdk-mcp

See mcp/README.md for the Claude Desktop config, the full tool list, and development setup.

openapi.json — an OpenAPI 3.1 description of the same API surface. FMP publishes no OpenAPI/Swagger document; this file is generated by introspecting this library's source (python tools/gen_openapi.py), not fetched from or endorsed by FMP.
