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
Returns a paginated list of transactions/token transfers matching the filters, each including hash, from/to addresses, value, fee, method called, status, timestamp, block number, token details, and transfer indices. Also returns applied search parameters and next-page cursor for pagination.
Example use cases
Wallet activity audit for compliance
“Show me all outgoing transactions from wallet 0xDEADBEEF on Polygon (chain ID 137) between January 1 and March 31, 2024, so I can review its activity.”
DeFi protocol method call analysis
“Find all transactions that called the 'swap' method on Uniswap's contract 0xUNISWAP on Ethereum over the past week — I want to see how often it's being used.”
Token transfer monitoring for a specific token
“Search for all transfers of the token at contract address 0xTOKEN123 on Arbitrum (chain ID 42161) where the amount is between 1000 and 50000 tokens.”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/advanced-filtersWhen to prefer
Use this endpoint when you need granular, multi-criteria filtering of on-chain transactions across specific blockchains supported by Blockscout — particularly when you need to combine filters like address, token contract, method name, amount range, and time window simultaneously. Prefer this over basic block explorers when you need programmatic, cross-chain transaction search with advanced filter combinations.
Side effects
- Invalid chain_id returns error or empty results
- Malformed address hashes return 400 or empty items array
- Overly broad filters may return large paginated results requiring cursor navigation
- Unsupported chain IDs not indexed by Blockscout return errors
- Invalid date format in age_from/age_to causes query failure
- Payment failure (x402) blocks access if USDC balance insufficient
