How this service works
Evidence-backed npm package upgrade decisions for coding agents.
Output
Returns a JSON object containing the total transaction count for the address within the specified block window, plus a breakdown of incoming and outgoing standard token transfer log counts.
Example use cases
Wallet due diligence before payment
“Before I send funds to 0xAbCd...1234 on Base, can you check how active that address has been in the last 1000 blocks? I want to know its transaction count and whether it's been sending or receiving tokens.”
Detect dormant or bot-like addresses
“I need to know if the Base wallet 0x9876...fedc has been unusually active in the last 5000 blocks — give me the transaction count and a breakdown of incoming versus outgoing token transfers.”
Monitor new contract deployer activity
“Check the on-chain activity for address 0xDead...Beef on Base Sepolia over the past 200 blocks and tell me how many transactions they've made and what the token transfer counts look like.”
Technical details
Endpoint
POSThttps://x402-safe-upgrade-api.onrender.com/v1/address-activity-summary?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cost-effective on-chain activity snapshot for a specific EVM address on Base or Base Sepolia without querying a full blockchain explorer. It is ideal for agents performing wallet due diligence, detecting dormant or highly active addresses, or enriching address metadata prior to a transaction or interaction. Prefer this over general-purpose blockchain RPCs when you want a structured summary (transaction count + transfer log breakdown) in a single call.
Side effects
- Invalid or malformed 0x address returns an error response
- Unsupported chain value (not 'base' or 'base-sepolia') causes a validation error
- windowBlocks exceeding 5000 or below 1 is rejected
- Payment not provided or insufficient USDC results in a 402 Payment Required response
- Address with zero activity returns counts of 0 (not an error but may be unexpected)
- Node or indexer unavailability on the specified chain causes a service error
