Steve here from the OpenAI team–this means a lot! We really hope you enjoy building on it

sdcoffeyon New tools for building agents

Hey there! This is Steve here from the OpenAI team–I worked on the Responses API. We have not removed this! It should still work just like before! Here's an example:

sdcoffeyon Show HN: Kysely, a type-safe SQL query builder for TypeScript

We've been using this in production for several months, and I'm a huge fan. Unopinionated but incredibly helpful. Big ups to the authors!

sdcoffeyon Harvesting credit card numbers and passwords from your site (2018)

A classic

sdcoffeyon Show HN: Cognate – Stack oriented programming in English prose

This is cool - always wondered if something like this was possible/desirable. What do you see as the ideal use cases for Cognate?

sdcoffeyon Ask HN: Where do you get your financial data?

We're mainly looking at publicly-traded US securities, including stocks, ETFs, and crucially, mutual funds. Many sources (looking at you, Polygon) don't publish price data for mutual funds. Haven't heard of MarketQA, will definitely check it out

sdcoffeyon Ask HN: Where do you get your financial data?

It is indeed, which is why we stopped after window-shopping Bloomberg and Nasdaq. Seems like it's hard to have cost-effective, high-quality data with and API that's amenable to bulk backfilling.

We have actually looked at Intrinio! Specifically for options data. Again the problem was that the API is not setup for bulk, historical backfills.

sdcoffeyon Ask HN: Where do you get your financial data?

Multi-month, wow. Cool to know this exists though, thanks!

sdcoffeyon Ask HN: Where do you get your financial data?

Interesting! I'm no longer a student, so I couldn't get access, but it's cool to know that this exists.

Curious if you've used any of these WRDS data sets? Also really interested to know if you've used the postgres interface to this data, and how you liked working with it as opposed to a regular API-like interface. Thanks!

sdcoffeyon Show HN: Find the 10 highest and 10 lowest correlations to any stock

This is pretty easy to do in SQL too!

sdcoffeyon Show HN: Factor.fyi – use SQL to visualize financial, crypto and econ datasets

Thanks! We don't pay for any of our current datasets. Certain types of data we will eventually have to pay for (e.g., deep options data, short interest). We'll eventually onboard some of these as we see interest, but for now we're optimizing for publicly available but disparate datasets.
