x402
ChainScope Address Activity is a paid API for AI agents from chainsscope.duckdns.org, paid per call via x402, $0.015/call, status unknown (last checked 2026-09-13).
Retrieves recent transaction activity for a wallet address on Ethereum, Base, Bitcoin, or Solana, returning a list of transactions with value, direction, counterparty, and timestamp.

How this service works
Recent transaction history for an address, normalized across Ethereum, Base, Bitcoin, and Solana -- direction, counterparty, and value where the chain's data model makes that derivable.
Output
Returns a JSON object containing the chain name, the queried address, and an array of activity records — each with a transaction hash, the value transferred, the direction (in or out), the counterparty address, and an ISO 8601 timestamp of when the transaction occurred.
Example use cases
Audit suspicious wallet before payment
“Before I send funds to 0xbbbb000000000000000000000000000000bbbb on Ethereum, can you check its recent transaction history so I can see who it's been dealing with and whether it looks legitimate?”
Track DeFi wallet activity
“I want to review the last few transactions on my Base wallet 0x1f5f8474fA0dc1Fde79187abd68Ef8Ea15ADAe34 — show me what went in and out and who the counterparties were.”
Investigate counterparty on Solana
“Someone paid me from a Solana address and I want to understand their on-chain history — can you look up recent activity for that address and tell me what directions and values are showing up?”
Technical details
Endpoint
POSThttps://chainsscope.duckdns.org/tools/address-activityWhen to prefer
Choose this endpoint when you need a unified, cross-chain transaction history lookup without building separate integrations for Ethereum, Base, Bitcoin, and Solana. It is ideal for agents that need to audit wallet behavior, verify counterparty activity, or trace fund flows across multiple chains through a single consistent interface.
Side effects
- Invalid or malformed address for the specified chain returns an error
- Unsupported chain identifier causes a rejection
- Address with zero transaction history returns an empty activity array
- Network congestion or node unavailability on the target chain causes a timeout
- Incorrect x402 payment or insufficient USDC balance results in payment failure
