🎉 UPDATE 2021-Nov-3: Opensea officially updated their API. You can get accurate realtime floor prices from this endpoint: https://api.opensea.io/api/v1/collection/{slug}/stats:
const axios = require("axios");
async function getFloorPrice(slug) {
try {
const url = `https://api.opensea.io/collection/${slug}/stats`;
const response = await axios.get(url);
return response.data.stats.floor_price;
} catch (err) {
console.log(err);
return undefined;
}
}
await getFloorPrice("lostpoets");
await getFloorPrice("treeverse");
await getFloorPrice("cool-cats-nft");If you need floor prices, please use the official API (see above 👆👆👆). This scraper still can be used to scrape additional information about offers (tokenId, name, tokenContractAddress and offerUrl) as well as the ranking.
npm install opensea-scraperℹ slug is the human readable identifier that opensea uses to identify a collection. It can be extracted from the URL: https://opensea.io/collection/{slug}
ℹ options is an object with the following keys
debug[Boolean] launches chromium locally, omits headless mode (default:false)logs[Boolean]: display logs in the console (default:false)sort[Boolean]: sorts the offers by lowest to highest (default:true)browserInstance[PuppeteerBrowser]: bring your own browser instance for more control
const OpenseaScraper = require("opensea-scraper");
// which nft project to scrape?
const slug = "cool-cats-nft";
// options
const options = {
debug: false,
logs: false,
sort: true,
browserInstance: undefined,
}
// get basic info (from the opensea API)
const basicInfo = await OpenseaScraper.basicInfo(slug);
// get offers from opensea. Each offer includes the floor price, tokenName,
// tokenId, tokenContractAddress and offerUrl
let result = await OpenseaScraper.offers(slug, options);
console.dir(result, {depth: null}); // result object contains keys `stats` and `offers`
// get offers from opensea using a custom link
// Opensea supports encoding filtering in the URL so this method is helpful for getting
// a specific asset (for example floor price for a LAND token from the sandbox collection)
let url = "https://opensea.io/collection/sandbox?search[sortAscending]=true&search[sortBy]=PRICE&search[stringTraits][0][name]=Type&search[stringTraits][0][values][0]=Land&search[toggles][0]=BUY_NOW";
result = await OpenseaScraper.offersByUrl(url, options);
console.dir(result, {depth: null}); // result object contains keys `stats` and `offers`
// get offersByScrolling from opensea. This is an alternative method to get the same
// data as in the function `offers`, with the only difference that the data is here
// scraped actively by scrolling through the page. This method is not as efficient
// as the `offers` method, but it can scrape more than 32 offers. You could even scrape
// a whole collection with ~10k spots (this is not recommended though).
let resultSize = 40; // if you need less than 32 offers, please use the function `offers()` instead
result = await OpenseaScraper.offersByScrolling(slug, resultSize, options);
console.dir(result, {depth: null}); // result object contains keys `stats` and `offers`
// get offersByScrollingByUrl from opensea using a custom link instead of the slug
// the same logic applies as in `offersByScrolling()`
// Opensea supports encoding filtering in the URL so this method is helpful for getting
// a specific asset (for example floor price for a LAND token from the sandbox collection)
url = "https://opensea.io/collection/sandbox?search[sortAscending]=true&search[sortBy]=PRICE&search[stringTraits][0][name]=Type&search[stringTraits][0][values][0]=Land&search[toggles][0]=BUY_NOW";
resultSize = 40; // if you need less than 32 offers, please use the function `offers()` instead
result = await OpenseaScraper.offersByScrollingByUrl(url, resultSize, options);
console.dir(result, {depth: null}); // result object contains keys `stats` and `offers`
// scrape all slugs, names and ranks from the top collections from the rankings page
// "type" is one of the following:
// "24h": ranking of last 24 hours: https://opensea.io/rankings?sortBy=one_day_volume
// "7d": ranking of last 7 days: https://opensea.io/rankings?sortBy=seven_day_volume
// "30d": ranking of last 30 days: https://opensea.io/rankings?sortBy=thirty_day_volume
// "total": scrapes all time ranking: https://opensea.io/rankings?sortBy=total_volume
// "chain" is one of the following: "ethereum", "matic", "klaytn", "solana"
// if chain is unset, all chains will be selected by default
const type = "24h"; // possible values: "24h", "7d", "30d", "total"
const chain = "solana";
const ranking = await OpenseaScraper.rankings(type, options, chain);To investigate an issue turn on logs and debug mode (debug: true and logs: true):
const result = await OpenseaScraper.offers("treeverse", {
debug: true,
logs: true
});if you want to customize the settings for your puppeteer instance you can add your own puppeteer browser instance in the options. 🚧 IMPORTANT: I recommend using stealth plugin as otherwise you most likely won't be able to scrape opensea. If you find a way without using the stealth plugin please report in the form of an issue!
const puppeteer = require('puppeteer-extra');
// add stealth plugin and use defaults (all evasion techniques)
const StealthPlugin = require('puppeteer-extra-plugin-stealth');
puppeteer.use(StealthPlugin());
const myPuppeteerInstance = await puppeteer.launch(myCustomSettings);
const result = await OpenseaScraper.offer("cool-cats-nft", {
browserInstance: myPuppeteerInstance
});npm run demoTo test the functions in an REPL node environment that has OpenseaScraper service preloaded simply run:
node --experimental-repl-await -i -e "$(< init-dev-env.js)"I recommend saving an alias:
alias consl='node --experimental-repl-await -i -e "$(< init-dev-env.js)"';Open PR or issue if you would like to have more features added.
Thanks for your support!
