How this service works

Fast, low-cost Base data for autonomous agents. No API keys, no subscriptions; pay per call with USDC over x402.

Output

Returns a JSON object containing the network identifier (eip155:8453), a count of matching transfers, and an array of transfer records matching the filter criteria (token, from/to address, block range).

Example use cases

Audit inbound token payments to agent wallet

“Show me every ERC20 transfer that came into my agent wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Base between blocks 19000000 and 19500000 — I need to verify which payments arrived.”

Track USDC distribution from treasury

“Get all transfers of USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) sent from our treasury at 0xAbCd1234abcd1234abcd1234abcd1234abcd1234 on Base since block 18000000 so I can reconcile payouts.”

Monitor token activity for a specific contract

“Fetch all ERC20 transfer events for the token at 0x4200000000000000000000000000000000000006 on Base from block 21000000 to 21050000 — I want to see who has been moving it recently.”

When to prefer

Choose this endpoint when you need lightweight, pay-per-call ERC20 transfer lookups on Base mainnet without API key setup or subscriptions. It is ideal for agents that need on-demand, cost-efficient Base transfer data with flexible filtering by token, sender, recipient, and block range. Prefer over general blockchain explorers when operating in a trustless, autonomous context with USDC micropayment settlement.

Side effects

Invalid EVM address format (not matching 0x + 40 hex chars) returns validation error
Block range too wide may return timeout or empty results
No transfers matching filters returns count:0 and empty transfers array
Payment failure via x402 prevents access to data
Querying a non-ERC20 contract address may yield no results
