How this service works
Transaction count/nonce for one Base address for $0.001 USDC via eth_getTransactionCount. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns the nonce (transaction count) for the queried Base address — an integer representing how many transactions the account has sent, usable directly as the nonce field when constructing a new transaction.
Example use cases
Pre-flight nonce check before signing
“Before I broadcast this transaction on Base, look up the current nonce for my wallet 0x742d35Cc6634C0532925a3b8D4C9B8f3e1234567 so I can set the correct sequence number.”
Detect stuck pending transaction
“Can you check the on-chain transaction count for Base address 0xAbCd1234567890EfAbCd1234567890EfAbCd1234 and compare it to what my wallet shows? I think I have a stuck pending transaction.”
Verify account activity on Base
“How many transactions has the Base wallet 0x1111222233334444555566667777888899990000 ever sent? I want to know if it's ever been used on-chain.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/base-nonceWhen to prefer
Choose this endpoint when an agent needs a quick, pay-per-call nonce lookup on the Base network without managing an RPC node or API key. Ideal for transaction construction pipelines, fraud checks, or account activity probes where calling a public RPC directly is inconvenient or requires infrastructure setup. The $0.001 USDC x402 pricing makes it cost-effective for low-volume or on-demand lookups.
Side effects
- Invalid or malformed Ethereum address returns an error response
- Address with no transaction history returns 0 (valid but may confuse callers expecting activity)
- Network or RPC unavailability causes a 5xx or timeout
- Payment failure (insufficient USDC balance or x402 protocol error) blocks the request
