I’m trying to fetch NFT collections sorted by their trading volume but running into some issues. When I look at the OpenSea website rankings page, I can see collections properly arranged by volume metrics. However, when I try to use their API endpoints, I can only retrieve individual assets without any sorting options. The API seems to only return items based on creation date rather than volume data. Has anyone figured out how to get collection rankings with volume sorting through the OpenSea API? I need to pull this data programmatically for my project but can’t find the right endpoint or parameters to achieve this sorting functionality.
OpenSea’s API doesn’t let you sort by volume directly, even though their website obviously has this data. Hit the same wall last year building a portfolio tracker. Here’s what worked: grab volume data from their collection stats endpoint, then sort it yourself on the client side. You’ll make more API calls since you need separate requests for each collection’s stats, but you get the volume metrics you need. The endpoint gives you 24h, 7d, and total volume fields to sort by. Watch their rate limits though - I had to add throttling so I wouldn’t get blocked. Not as clean as a single sorted endpoint, but it works reliably.
Interesting challenge! I’ve been working with OpenSea’s API recently and hit similar walls.
Do you need real-time volume data or would historical rankings work? Have you tried combining their collection stats endpoint with custom sorting on your end?
What timeframe are you targeting - 24hr, 7day, or something else? Their website’s ranking algorithm probably factors in more than raw volume… maybe floor price changes or transaction count too.
You might want to check out Moralis or Alchemy APIs - they often have better sorting features than the official ones. What’s your project about? Sounds cool!
Also, are you running into rate limits while testing? That’s been my biggest pain point with OpenSea’s endpoints lately 
openSea’s api docs are trash, not gonna lie. when their endpoints couldn’t do what I needed, I just scraped their rankings page directly. not the cleanest solution but it worked. you could also try multiple api calls to grab collection stats and sort them yourself, but that’ll be painfully slow if you’re dealing with tons of collections.
