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 JSON object with four string-typed counters: transactions_count (total transactions sent/received), token_transfers_count (total ERC-20/ERC-721/ERC-1155 transfers), gas_usage_count (total gas consumed by the address), and validations_count (number of blocks validated, relevant for validators/miners).
Example use cases
Wallet activity audit for due diligence
“Can you check how many transactions and token transfers the address 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B has made on Ethereum mainnet? I'm vetting this wallet before doing business with them.”
Validator performance check
“I want to know how many blocks the address 0x00000000219ab540356cBB839Cbe05303d7705Fa has validated on Ethereum — can you pull that from Blockscout?”
DeFi contract usage metrics
“Can you get me the total transaction count and gas usage for the Uniswap v3 contract 0x1F98431c8aD98523631AE4a59f267346ea31F984 on the Polygon network using Blockscout?”
Technical details
Endpoint
GEThttps://api.blockscout.com/%7Bchain_id%7D/api/v2/addresses/%7Baddress_hash_param%7D/countersWhen to prefer
Use this endpoint when you need a quick, aggregated summary of an address's on-chain activity without paginating through full transaction lists. It is ideal for due diligence, activity scoring, or dashboard widgets. Prefer this over full transaction list endpoints when you only need counts, not individual transaction details. The multichain support via chain_id makes it useful for cross-chain wallet profiling.
Side effects
- Invalid or malformed address_hash returns an error or empty response
- Unsupported or invalid chain_id returns a 404 or error
- Address exists but has zero activity — counters return '0' strings
- Rate limiting or payment failure returns a 402 or 429 status
- Chain not indexed by Blockscout returns a not-found error
