Crypto Shark Bazaar – Chain Transaction Count
x402
Crypto Shark Bazaar – Chain Transaction Count is a paid API for AI agents from cryptoshark.duckdns.org, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).
Returns the current transaction count for a blockchain address or network on Base, useful for nonce management and activity monitoring

How this service works
Low-cost x402 blockchain primitives, market intelligence, and AI utilities for autonomous agents
Output
A JSON object containing the blockchain network name (e.g. 'base'), the transaction count for the queried address or network, and an ISO 8601 timestamp indicating when the data was observed (observedAt).
Example use cases
Nonce lookup before transaction submission
“Before I send a transaction from my wallet 0xAbC...123 on Base, can you fetch its current transaction count so I can set the right nonce?”
Wallet activity audit for onboarding
“I want to check how many transactions the address 0xDeF...456 has made on the Base blockchain — can you pull that count for me?”
Monitor wallet activity over time
“Can you grab the current on-chain transaction count for address 0x789...GHI on Base and tell me when it was last observed?”
Technical details
Endpoint
GEThttps://cryptoshark.duckdns.org/chain/transaction-count?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a low-cost ($0.001 USDC), on-demand transaction count or nonce lookup for a wallet address on the Base blockchain via the x402 micropayment protocol. It is ideal for autonomous agents that need nonce management before submitting transactions, lightweight wallet activity checks, or time-stamped on-chain data snapshots without setting up their own RPC infrastructure.
Side effects
- Invalid or malformed wallet address returns an error response
- Unsupported network identifier results in a 400 or equivalent error
- Rate limiting or payment failure via x402 protocol returns a 402 Payment Required
- Network timeout if the Base RPC node is slow or unavailable
- Empty or missing query parameters may return a generic or null count
