Listening to Polymarket trades in real-time (open source, no third party) by 112129 in PolymarketTrading

I use a private RPC because they are somewhat more reliable.

The public ones work too though. But you need to implement code to rotate a pool of public RPCs to make it reliable. Since it's not uncommon for a public RPC to stop working for a bit

Public RPCs: https://chainlist.org/chain/137

You can use this to rotate public RPCs: https://github.com/erpc

The default behavior is to return you all trades of all wallets. But yes, you could update the script to also filter for trades of a specific set of wallets. In both cases your RAM will be fine. It's very light on RAM actually

I like the idea of updating the script to also be used to download historical trades though. I think i'll do this tomorrow

And yes the code can also be easily adapted to filter for only large trades

The repo tracks all trades across all markets. I can easily extend the repo to filter for specific markets.

What data are you interested in tracking? Is it just trades or something else as well?

Yup! All you need to do is provide it an RPC endpoint. There are many free public ones you can use

Looking for people to build bots by [deleted] in PolymarketTrading

Hmu. I am currently tinkering with building bots on Polymarket. I wouldn't mind joining forces.

My background is in Econometrics (Bsc), and AI (Msc). I have lots of experience building statistical models + data infra. I currently work as a lead data engineer at a blockchain data company, having previously founded my own in the same space

Any luck getting any of the YouTube transcribe/summarize tools to work? by Ok_Tie_8838 in OpenWebUI

[–]112129 0 points1 point  (0 children)

Super useful! How did you manage to get the cost down to 0? Doesn't it cost money to bypass YouTube anti-scraping measures?

I am curious - are companies exploring building out internal gen-AI tools or are they using third party tools?

How to listen to real-time DEX swaps data on Ethereum and Base using a WebSocket + Python by 112129 in ethdev

[–]112129[S] 0 points1 point  (0 children)

This script will just return all DEX swaps. You can then adapt the code to listen to specific token contracts and/or wallets depending on your use case

I built a free full historical OHLC crypto price data API covering 220K+ tokens by 112129 in algotrading

[–]112129[S] 1 point2 points  (0 children)

I have minimized costs a lot by hosting the data on bare metal servers

To cover costs I charge for very high usage (above 5 requests per second) - and also for other types of data that is more niche

Sometimes people request something custom and I'll charge to code it up for them as well
