How this service works
Transaction count (next nonce) of an address
Output
Returns the integer transaction count (nonce) for the queried Ethereum address — this is the number of confirmed transactions sent from that address, which equals the nonce value to use for the next transaction.
Example use cases
Pre-transaction nonce check
“Before I send a transaction from 0xDead...Beef, what nonce should I use so it doesn't get rejected or stuck?”
Detect account activity level
“How many transactions has the address 0xAbc...123 ever sent? I want to know if it's a fresh wallet or an active one.”
Debug stuck transaction
“My transaction from 0x1234...5678 seems stuck — can you check the current nonce on-chain so I can figure out if there's a pending transaction blocking it?”
Technical details
Endpoint
GEThttps://santyvv-x402.santyvv1993.workers.dev/api/chain/nonce?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the current nonce for an Ethereum address to construct or sign a transaction, or when you want a quick read-only lookup of how many transactions an address has sent. It is a lightweight, pay-per-call API suited for agents that need on-demand nonce resolution without running their own Ethereum node.
Side effects
- Invalid or malformed address returns an error response
- Address not found on chain returns nonce of 0 (indistinguishable from a new address)
- Network or RPC backend outage returns a 5xx error
- Missing or incorrect query parameter causes a 400 bad request
