x402
Mint Intel: Base Chain Nonce Lookup is a paid API for AI agents from mintintel.35-171-220-195.sslip.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-31).
Returns the next transaction nonce (and pending transaction count) for any Base wallet address using eth_getTransactionCount.

How this service works
Next transaction nonce for any Base wallet via eth_getTransactionCount (latest + pending) - how many transactions it has sent and how many are still pending.
Output
Returns a JSON object containing the queried wallet address and its nonce (integer), representing the total confirmed transaction count (latest) plus any pending transactions from eth_getTransactionCount, indicating what sequence number to use for the next transaction.
Example use cases
Pre-flight check before sending Base tx
“Before I submit my next transaction on Base, can you look up the current nonce for 0xAbCd1234567890AbCd1234567890AbCd12345678 so I know the right sequence number to use?”
Detect stuck pending transactions
“Check if 0x742d35Cc6634C0532925a3b844Bc454e4438f44e has any stuck pending transactions on Base — I want to see if the nonce shows anything still waiting to be mined.”
Audit wallet activity count on Base
“How many total transactions has 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 ever sent on the Base chain? I want to audit its on-chain activity level.”
Technical details
Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/base/nonce/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the current transaction nonce specifically for a Base (Coinbase L2) wallet address — for example, before constructing or signing a transaction, detecting stuck/pending transactions, or auditing how many transactions an account has sent. Prefer this over Ethereum mainnet nonce endpoints when operating on Base; prefer it over full block explorers when you only need the nonce and not full transaction history.
Side effects
- Invalid or malformed address (not 0x-prefixed or wrong length) returns an error
- Address with no transaction history returns nonce of 0
- Network or RPC node unavailability causes a 5xx error
- Rate limiting may occur under high request volume
- Non-Base EVM addresses (e.g., Ethereum mainnet) may return incorrect nonce if account activity differs across chains
