How this service works
Free Base nonce sample for the service receiver. The paid $0.0026 API returns the exact next transaction nonce from one bounded read-only RPC call.
Output
Returns the exact integer nonce value representing the next valid transaction sequence number for the queried Base network address, derived from a single bounded read-only RPC call.
Example use cases
Pre-sign nonce check for Base transaction
“Before I broadcast this Base transaction, what's the current next nonce for my wallet so I can include the right sequence number in the signed payload?”
Detect pending transactions on Base account
“Check the next nonce for my Base address and compare it to what the local wallet thinks — I want to know if there are any pending transactions already in the mempool.”
Automated nonce management in DeFi bot
“My trading bot is about to send a transaction on Base — fetch the live next nonce for the sender address so it doesn't collide with any in-flight transactions.”
Technical details
Endpoint
GEThttps://appearing-clinics-show-wrote.trycloudflare.com/base-nonce-sampleWhen to prefer
Choose this endpoint when you need a fast, precise next-nonce value for Base network transactions with minimal RPC overhead. Ideal for transaction signing pipelines, DeFi bots, or any agent that must avoid nonce collisions on Base. Prefer over self-hosted RPC when you want a paid, bounded, reliable single-call guarantee rather than managing your own node infrastructure.
Side effects
- Invalid or malformed Ethereum address returns an error
- RPC node unavailable or rate-limited causes a failed response
- Network timeout if Base RPC endpoint is unreachable
- Free sample endpoint may return a fixed demo nonce rather than a live address-specific nonce
