NFT Checker
Discontinued Last verified: September 2026AI-powered NFT rarity, scam detection, and collection analytics tool. Discontinued; the domain no longer resolves.
nftchecker.io no longer resolves. Both nftchecker.io and www.nftchecker.io fail DNS resolution outright, and the domain is delegated to Cloudflare nameservers but publishes no A or AAAA record on any public resolver we tried, so nothing is served over HTTP or HTTPS. The most recent capture in the Internet Archive is from October 2025, and WHOIS records a fresh registration date of 13 April 2026, which means the domain lapsed and was picked up again. Do not treat the pricing and feature details below as current.
A second, separate problem: every archived copy of nftchecker.io we could retrieve shows a small free utility for verifying and sourcing NFT metadata from a contract address and token ID, credited to Art101, not the AI rarity-scoring, scam-detection, and portfolio-tracking suite this review describes. We could not confirm that the product described below ever existed at this address, and the ~$19/mo Pro price was only ever our own estimate, never a published vendor figure. We have kept the entry for reference rather than deleting it. If you need a working NFT rarity or analytics tool today, see the alternatives in the sidebar.
What is NFT Checker?
NFT Checker was a specialized analytics platform focused on NFT collections, offering AI-powered rarity scoring, scam detection, and collection analytics, and it is discontinued (see the status note above). For collectors who buy NFTs, the biggest risks are: (1) overpaying for items that aren't actually rare within a collection, (2) getting caught in copycat scam collections that imitate real ones, and (3) buying into collections that have wash trading or pump-and-dump dynamics. NFT Checker addressed all three with automated tools. Its rarity scoring used AI to analyze trait combinations and calculate a rarity rank for every NFT in a collection, which directly impacts floor prices and secondary market value. Its scam detection module used pattern analysis to flag suspicious collections, duplicate art, copycat names, wash-traded volume, or smart contract risks. For investors and flippers, a tool that combined rarity analysis and scam detection in one place was valuable, though the NFT market overall has cooled significantly from its 2021-2022 peak. NFT Checker's smaller community meant it was never as well-known as broader platforms like Nansen or Dune, but for collectors focused specifically on NFTs it provided targeted utility.
⚡ Quick Verdict
Nobody new, the site is offline. Historically, NFT collectors and investors evaluating collections for rarity, authenticity, and scam risk
Traders focused on DeFi tokens or large-cap cryptocurrencies
Unavailable as of August 2026, site offline. Previously listed as Free · Pro around $19/mo (our estimate, never published) · Enterprise custom
Previously a free tier with basic rarity checks, not reachable in August 2026
Dedicated NFT-focused AI for rarity scoring and scam pattern detection
Smaller community and less-established than broader analytics platforms
Bottom line: the 4.0/5 score below reflects our original May 2026 assessment and is no longer actionable. As of August 2026 nftchecker.io does not resolve, so there is nothing to sign up for. Use one of the alternatives instead.
Pricing
Cannot be verified in August 2026: nftchecker.io does not resolve, so there is no live pricing page to check. The figures below are preserved exactly as originally published in May 2026 and were themselves estimates rather than vendor-published numbers. Do not rely on them.
NFT Checker's pricing was never fully published publicly. The site indicated a Free tier for basic rarity checks and scam flagging, with a Pro tier we estimated at around $19/month based on comparable tools in the space, and Enterprise or institutional plans on request. The free tier was usually enough for casual collectors checking individual collections before minting or buying on secondary markets. None of these can be purchased now: the domain does not resolve and there is no site to sign up on.

FAQ
How much does NFT Checker cost?
As of August 2026 you cannot buy it at any price: nftchecker.io does not resolve on any public DNS resolver and serves no site, so the product appears to be offline or discontinued. For the record, our May 2026 review said NFT Checker offered a free tier for basic rarity and scam checks, with Pro pricing that was never publicized by the vendor and that we estimated at around $19/month based on comparable NFT analytics tools, plus Enterprise plans on request. That $19 figure was an estimate, not a published price, and we could never confirm it.
Does NFT Checker actually catch scams?
You cannot try it now, because the site is offline. Our May 2026 review found that it caught common fraud patterns, copycat collections, wash trading, duplicate art, and obvious rug pull indicators. It was not foolproof; novel scams or sophisticated fraud patterns could slip through, and it was best used as one of several due diligence steps rather than as the only check before a purchase.
How does AI rarity scoring work?
NFT rarity is determined by the combination of traits on each item. NFT Checker analyzed all NFTs in a collection, calculated the statistical frequency of each trait combination, and assigned a rarity score. Items with rare trait combinations command higher secondary market prices, so accurate rarity scoring directly impacts valuation. The tool is discontinued, so this scoring is no longer available.
Is the NFT market still worth watching in 2026?
NFT volumes are significantly down from the 2021-2022 peak, but the market hasn't disappeared, blue-chip collections still trade, new projects launch regularly, and on-chain gaming NFTs continue to develop. For collectors and investors still active in NFTs, tools of this kind are useful, but NFT Checker is not one of them any more: its domain no longer resolves. For anyone not actively in NFTs, you probably don't need a dedicated tool.
NFT Checker vs OpenSea native analytics?
OpenSea's native analytics cover basics like floor price and recent sales, but don't offer the depth of rarity scoring or scam detection that NFT Checker provided. That comparison is now moot, because NFT Checker is discontinued; for serious collectors, a dedicated tool like Rarity Sniper adds value on top of what OpenSea shows natively.
Can I use NFT Checker for portfolio tracking?
Not any more. NFT Checker included portfolio tracking for NFT holdings across multiple wallets, showing cost basis, current floor value, and unrealized gains or losses, which was useful for tax reporting and for monitoring overall NFT portfolio performance. The site no longer resolves, so that tracking is unavailable.
📋 Good to know
Not currently possible. nftchecker.io does not resolve as of August 2026, so the sign-up and wallet-connect flow described in our May 2026 review cannot be reached.
On-chain data is public. No custody of user funds.
Not applicable while the site is offline. Our May 2026 note read: free tier is usually enough for casual collectors, and Pro (estimated ~$19/mo) adds bulk checks and advanced filters if you're actively trading.
Low. The UI is designed for non-technical collectors.
