Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

Example use cases

DeFi wallet audit trail

“Get me all transactions sent from 0xDEF...456 to 0xABC...123 in descending order from block 18000000 to 19000000, with metadata included, so I can audit their DeFi activity.”

NFT transfer history review

“Fetch the last 100 NFT-category transactions received by wallet 0x789...ABC in ascending order — I want to trace the full NFT transfer history for this address.”

Smart contract interaction log

“Show me all non-zero-value transactions sent to smart contract 0x111...222, up to 25 results, with metadata, so I can see who has been interacting with it recently.”

When to prefer

Choose this endpoint when you need fast, multi-network blockchain transaction history with flexible filtering by address, block range, category, and sort order, especially when paying per-call via x402 is acceptable and you need access to 57+ chains without managing your own node infrastructure.
