Hi dcts, is it possible to use your code to scrape specific trading data of an NFT, like last sales price?

You can use the official Opensea API to get last sales prices, only the floor prices are not in realtime thats why scraping them makes sense to get more precise data points.

To retrieve latest sales data check official Opensea API documentation.

Heres an example (it fetches the latest sales from treeverse):
https://api.opensea.io/api/v1/events?collection_slug=treeverse&event_type=successful&only_opensea=false&offset=0&limit=20

Hi, thanks for your kind answer! I know about the API, but I'm trying to get the data via scraping, because I found it to be more of an interesting challenge.

Oh ok, well, you for sure can get it through scraping, probably I would do the following:

• open the url with the activity tab open https://opensea.io/collection/sneaky-vampire-syndicate?tab=activity
• then scrape the table with the recent sales

Good luck with the challenge! 🚀💪

This works locally, cloudflare is bypassed. Unfortunately when deployed to any cloud it stopps working. I tried

take a look at https://rapidapi.com/restyler/api/scrapeninja it seems to work fine with opensea, at least with api.opensea graphql requests.
