How this service works
Compare confirmed and pending Base nonces before an autonomous transaction is signed.
Output
Returns the current confirmed nonce, pending nonce, and a readiness verdict indicating whether it is safe for an autonomous agent to sign and submit a new transaction — including any detected nonce gap or conflict that could cause the transaction to be rejected or queue behind a stuck pending transaction.
Example use cases
Pre-payment nonce safety check
“Before sending the next x402 payment from wallet 0xDe45...F7, check whether the confirmed and pending nonces on Base are aligned and it's safe to sign a new transaction right now.”
Detecting a stuck pending transaction
“My agent wallet 0x1aB2...9cD seems stuck — can you compare its confirmed and pending nonces on Base to see if there's a nonce gap that would block a new transaction from going through?”
Autonomous agent pre-flight validation
“I'm about to kick off an autonomous agent workflow that submits Base transactions — run a nonce readiness check on 0xF00...BAR first so we don't accidentally broadcast a conflicting or out-of-order transaction.”
Technical details
Endpoint
GEThttps://nohands-coinbase-bazaar.bytoken2023.workers.dev/v1/x402/base/nonce-readiness?utm_source=zero.xyzWhen to prefer
Use this endpoint immediately before an autonomous agent signs any Base transaction, especially in x402 payment flows or multi-step agent workflows where nonce collisions or stuck pending transactions could cause failures. Prefer this over reading raw RPC nonce values yourself when you need a simple pass/fail readiness verdict rather than raw chain data.
Side effects
- Invalid or malformed Base wallet address returns an error response
- RPC connectivity issues to Base network result in timeout or unavailable status
- Address with no transaction history may return edge-case nonce values requiring agent interpretation
- Rapidly changing chain state may cause stale nonce snapshot between check and actual submission
