How this service works
Explore crypto activities with Blockscout's multichain search. Find transactions, addresses, tokens, and dapps across top blockchain networks — your go-to explorer for cross-chain blockchain data
Output
A paginated list of NFT token records, each including the token name, symbol, type, decimals, icon URL, address hash, total supply, exchange rate, holder count, circulating market cap, and chain-specific metadata. Also includes next_page_params for cursor-based pagination.
Example use cases
Cross-chain NFT collection discovery
“Find all NFT collections called 'CryptoPunks' across every blockchain in the cluster and show me their contract addresses, total supply, and how many holders each one has.”
NFT symbol lookup for trading research
“Search Blockscout's multichain NFT index for tokens with the symbol 'BAYC' and give me their exchange rates and circulating market caps across all chains.”
NFT due diligence before purchase
“I want to verify an NFT project — search for 'Azuki' NFTs in the Blockscout multichain cluster on Ethereum and Polygon only, and show me up to 5 results with their holder counts and supply details.”
Technical details
Endpoint
GEThttps://api.blockscout.com/services/multichain/api/v1/clusters/%7Bcluster_id%7D/search/nftsWhen to prefer
Use this endpoint when you need to search NFT collections across multiple blockchain networks simultaneously within a Blockscout cluster, especially when you need cross-chain coverage with metadata like holder counts, market cap, and supply. Prefer this over single-chain block explorers when the target chain is unknown or when comparing the same NFT project across networks.
Side effects
- Invalid or missing cluster_id returns a 404 or error response
- Unsupported chain_id values may return empty results or validation errors
- Empty query string may return unfiltered or empty results
- Rate limiting or payment failure (x402) if the $0.012 USDC fee is not provided
- Malformed page_token causes pagination errors
- Very broad queries may return large result sets requiring multiple paginated calls
