How this service works
Recent USDC transfers in and out of any address on Base, read live from the chain (Transfer event logs over roughly the last ~600 blocks, about 20 minutes; the window narrows automatically if the public node rejects a wider range). Pass ?address=0x... . Returns up to 50 entries with block, tx hash, from, to, amount. No third-party API, no cache.
Output
Returns up to 50 USDC Transfer event entries from roughly the last 600 Base blocks (~20 minutes), each including block number, transaction hash, sender address, recipient address, and USDC amount. Data is read live from a public Base node with no caching or third-party intermediary.
Example use cases
Confirm incoming payment received
“Did the address 0xAbc123...def receive any USDC in the last 20 minutes on Base? I'm waiting on a payment and want to confirm it hit.”
Audit wallet activity before a deal
“Before I proceed, can you check the recent USDC transfer history for 0xDead...Beef on Base and tell me who they've been sending to and receiving from?”
Agent monitors for USDC inflows
“Keep an eye on 0x1234...5678 and let me know as soon as it receives any USDC on Base — check the latest transfer logs for me now.”
Technical details
Endpoint
GEThttps://oraclepost.higgsfield.app/api/premium/transfersWhen to prefer
Choose this endpoint when you need live, uncached, on-chain USDC transfer history for a specific Base address without relying on a third-party indexer or API key. It is ideal for real-time payment verification, quick wallet audits, or agent workflows that need trustless confirmation of recent USDC flows. Prefer it over indexer APIs when recency (last ~20 min) and raw chain truth matter more than deep historical coverage.
Side effects
- Public node rejects wide block range — window narrows automatically but may return fewer results
- Invalid or malformed address (non-0x-prefixed or wrong length) — likely returns error or empty result
- No transfers found in the window — returns empty list, not an error
- Public node rate limiting or downtime — request may fail or time out
- Very active addresses may hit the 50-entry cap, truncating older transfers within the window
