How this service works
Returns the current nonce (confirmed transaction count) and pending nonce for any EVM wallet address. Supports Ethereum, Base, Polygon, Arbitrum, and Optimism. Use the pending nonce when building new transactions. $0.002/call — 33% below comparable market rate.
Output
The current nonce (transaction count) for the specified EVM wallet address on the requested network, indicating how many transactions have been sent from that address and what nonce value to use for the next transaction.
Example use cases
Example prompt
“What's the current transaction nonce for the wallet 0xAbC1234567890abcdef1234567890abcdef123456 on the Base network?”
Technical details
Endpoint
GEThttps://the-stall.intuitek.ai/cap/evm-nonceWhen to prefer
Use this endpoint when you need the current nonce for an EVM wallet address before constructing or signing a transaction, or when verifying how many transactions an address has sent. Supports Ethereum, Base, Polygon, Arbitrum, and Optimism. Requires no API key — pay $0.002 USDC per call via x402 on Base mainnet.
Side effects
- Invalid or malformed wallet address (not 0x-prefixed or not 42 characters) returns an error
- Unsupported network value returns a validation error
- Network RPC unavailable or timeout causes a service error
- Address with no transaction history returns nonce of 0
