OpenSea Scraper API
OpenSea's official API wants an approved key, meters its rates, and already deprecated one version – a stack of dependencies for data the site displays publicly. Our scraper API taps the public layer directly: collection rankings, floor prices, volumes, and listing data, no key application in the loop.
* This scraper is now a part of the Web Scraping API.

What is OpenSea scraper API?
OpenSea scraper API centers on the two page families that carry the market:
Rankings pages
- Collection ranks by volume across time windows
- Floor prices, owner counts, and supply figures
Collection and asset pages
- Live listings with prices and traits
- Sales activity and price-history signals
Floor price is the number this market watches the way equities watch tickers, and its movement is the tracker use case in its purest form – sampled floors become time series, time series become alerts. NFT analytics products, portfolio valuators, and trait-rarity tools all draw from these same public surfaces – no OpenSea API key in the dependency chain.

Collect OpenSea data
Floor-price tracking is a sampling-cadence problem with a rendering problem inside it. The Web Scraping API renders the rankings and collection pages – React-heavy surfaces where nothing useful exists before JavaScript runs, patterns covered in our guide to collecting data from JavaScript-rendered pages – and scheduled sweeps turn displayed floors into per-collection series. Delta alerts on those series are what trading tools actually sell.

Frequently asked questions
Is it legal to scrape OpenSea?
New formats don't arrive with new exemptions. Data about tokens and marketplaces like OpenSea gets judged under rules written for older things. Expect the familiar questions to apply. Our how existing law treats new formats covers it.
How does the OpenSea scraper API bypass blocks and CAPTCHAs?
Cloudflare screening plus platform-level rate limiting form the visible defense. Requests present fully rendered, browser-coherent sessions, rotate across the exit pool, and retry challenges automatically – a posture that sustains minute-level floor sampling without drawing attention.
What output formats does the OpenSea scraper API support?
Rankings and collection pages convert to HTML, or to time-series-ready JSON with floor, volume, and supply typed – XHR capture recovers the numbers behind chart components when they live there.
Can I geo-target OpenSea requests to a specific country or city?
You can, though NFT market data reads identically worldwide – the chain doesn't localize. Origin distribution across the 195+ geo-locations serves sampling smoothness at high cadences, which is the operative geographic concern on this target.
How fast is the OpenSea scraper API and can it handle large-scale jobs?
Five-minute floor sampling across the top rankings is a light, punctual workload – small pages, tight loop. Mint-event bursts, when floors move by the minute, absorb into plan-tier concurrency, scheduling holds the interval discipline alerting products depend on, and ready-made scraping templates cover standard marketplace layouts on the setup side.
Can I try the OpenSea scraper API for free?
Yes – the free starter plan activates card-free and includes up to 2K requests. At 5-minute resolution on a handful of collections, that's a floor-tracking pilot before any spend.
