How this service works
Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
Output
Returns a JSON object containing the blockchain network name (e.g. 'eth'), the queried address, and the total transaction count (integer) for that address on-chain.
Example use cases
Wallet activity screening for DeFi
“Check how many transactions the wallet 0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae has made on Ethereum — I want to know if it's an active address before interacting with it.”
Smart contract interaction audit
“How many on-chain transactions has the contract at 0xabc123...def456 executed so far? I'm trying to assess how much usage it's seen.”
Crypto user due diligence
“I'm looking at this Ethereum address 0x1234567890abcdef1234567890abcdef12345678 — can you tell me its total transaction count so I can judge how seasoned this wallet is?”

Endpoint
GEThttps://x402-stock-indicators.vercel.app/transaction-count/%7Baddress%7DWhen to prefer
Choose this endpoint when you need a quick, pay-per-call on-chain transaction count for a specific blockchain address without committing to API keys or subscriptions. Ideal for agents that need occasional on-chain lookups billed in USDC via the x402 micropayment protocol, especially for Ethereum addresses.
Side effects
- Invalid or malformed blockchain address returns an error
- Unsupported chain identifier returns an error or empty result
- Payment failure via x402 (insufficient USDC balance or network issue) blocks the call
- Address with zero transactions may return count of 0
- Network timeouts on slow RPC nodes
