# YFIN API Now Returns Plain CSV on Most Endpoints. Add format=csv to the Same URL.

YFIN API, my free Yahoo Finance API, now returns a plain CSV on most endpoints. Add format=csv to the same URL and get a normal table back, no JSON to unwrap.

Multiple tickers. Every endpoint takes a comma-separated list of symbols, up to 25 in a single call, so a whole watchlist comes back in one request. Most used endpoints are prices, profile, financials and analyst price targets.

If you would rather talk to an agent and have it pull the data for you, the data pull agent is sitting here: [quants.tigzig.com](https://quants.tigzig.com)

And no, the data pull agent is not allowed to analyze the data and give a recommendation. It can just pull the data and generate it for you. However, it also generates an AI technical analysis report, with the technical analysis piece done by a different AI pathway. And yes, it can pull mutual fund NAVs also, for India only.
