Free API with GMX open interest, funding and liquidations next to CEX data.

Hi! I’m a 30-year-old trader and I build web apps as a hobby. For a long time I paid for the Coinglass API for my trading bots, until I decided to build my own data service, liquidvision.app.Open interest and funding match the exchanges’ own numbers - I check it every 10 minutes and publish the result at liquidvision.app/accuracy. The API is free, doesn’t need a key, and works well for trading bots and AI agents.

Last week I added GMX v2 on Arbitrum, so you can compare GMX open interest, funding and liquidations with Binance or Bybit in the same format: LiquidVision — Crypto Derivatives Data for Bots & AI Agents

Its just me working on this. Which other Arbitrum perp DEXs should I add? Would comparing DEX and CEX funding be useful for anyone here?

The data categories already exist across dashboards and exchange APIs. The potential value is easier, free and standardized GMX v2 data access alongside CEX metrics. The key question is data reliability, historical coverage, update frequency, rate limits and long term maintenance. @Oceanstorm

Thanks for the reply! Youre right, the data itself is nothing new. What I wanted is GMX in the same format as Binance or Bybit, so a bot can read both the same way.

About reliability - GMX liquidations come straight from the on-chain indexer, so nothing is missing there. For the exchanges I compare my numbers with their own APIs every 10 minutes and publish it at liquidvision.app/accuracy. For GMX I don’t have that check yet, I want to add it.

History is short for now. GMX is there only since 22 September, 103 markets, OI and funding updated about once a minute. The exchanges go back to July. You can download all of it as CSV. Limits are 240 requests a minute without a key and 300 with a free one.

Maintenance is the honest weak spot - its just me. I can’t promise what a team can, so I just measure it in public. Uptime is at liquidvision.app/status, 100% for the last 30 days and 99.8% since July.

What would be more useful for you - more Arbitrum perp DEXs or longer GMX history?
