Quick answer
FactSet exposes prices, fundamentals, estimates, ownership, tick history and news through REST APIs on developer.factset.com, with SDKs and cloud/Jupyter integrations. Limits are set per API (one published example is 20 requests per second per user) and access requires a FactSet licence.

Build a FactSet APIs strategy with AlgoGP
AlgoGP does not connect to FactSet APIs natively yet. FactSet APIs uses plain HTTPS with an API key, so it is a good candidate for a native adapter; it is not built in yet.

Design and backtest in AlgoGP
Describe the strategy to the copilot and backtest it on years of normalized history. The result does not depend on any vendor.

Export the Python project
Every project exports
strategy.py,market_data.py,brokers.pyandlive.py. The strategy only sees bars, cash, positions and orders, never a vendor’s wire format. - 3
Plug in FactSet APIs
Implement the four adapter methods (
account,positions,submit_market_orderand a candle fetcher) with FactSet APIs’s SDK, or keep a built-in platform for paper trading and add FactSet APIs when you go live.
Built-in data sources for the same markets: Alpaca, Yahoo Finance, Alpha Vantage, Tradier.
FactSet APIs API: frequently asked questions
Can individuals use FactSet APIs?
Generally no; APIs are available to licensed FactSet clients.
Design and backtest your FactSet APIs strategy first
AlgoGP turns an idea into Python and tests it on years of history before you connect it to FactSet APIs. The exported code keeps the broker behind four small adapter methods.
