How this service works
Transaction count (nonce) for a wallet address on Ethereum -- how many transactions it has sent, from Etherscan's V2 API. $0.005/call.
Output
Returns the total number of transactions sent from the specified Ethereum wallet address (the nonce), as an integer. This reflects on-chain data sourced from Etherscan's V2 API and represents lifetime outbound transaction activity for that address on Ethereum mainnet.
Example use cases
Nonce lookup for transaction signing
“What's the current nonce for Ethereum wallet 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B? I need it before I build a raw transaction.”
Wallet activity screening for onboarding
“Can you tell me how many transactions wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e has sent on Ethereum? I want to know if it's an established wallet or brand new before approving them.”
On-chain seniority research for airdrop eligibility
“Check the transaction count for Ethereum address 0xBE0eB53F46cd790Cd13851d5EFf43D12404d33E8 — I'm trying to see if it meets the minimum activity threshold for an airdrop.”
Technical details
Endpoint
GEThttps://www.x402financialdata.com/transaction-count/:address?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single, cheap, fast lookup of an Ethereum wallet's transaction count (nonce) without needing full balance or token data. It is ideal for pre-transaction nonce retrieval, wallet age/activity screening, or lightweight on-chain activity checks. Prefer the sibling 'Wallet Activity Overview' endpoint if you also need ETH balance or token holdings in the same call.
Side effects
- Invalid or malformed Ethereum address returns an error response
- Address with zero transactions returns count of 0 (not an error)
- Network or Etherscan API downtime may cause timeout or 5xx errors
- Only Ethereum mainnet ('eth') is supported; requests for other chains are unsupported
- Payment failure or insufficient USDC balance blocks the request via x402 protocol
