How this service works
Use when an agent must see who is accumulating or dumping a Base ERC-20 right now. Input: token address, minutes (1-60, default 60), limit (1-25). Output: JSON top net buyers and sellers (net, received, sent, contract or EOA), largest transfers with tx hash, volume, mints/burns, active wallets, covered window. Busy tokens get a shorter window. Example: ?address=0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed
Output
Returns a JSON object with: chain and chainId (Base/8453), token metadata (name, symbol, address, decimals, totalSupply, knownIssuer), window coverage details (from/to block and timestamp, whether window is complete, minutes covered), summary statistics (volume, transfers, transactions, active wallets, net buyers/sellers count, minted/burned), ranked lists of top net buyers and top net sellers (address, sent, received, net, isContract, transfersIn/Out, netPctOfSupply), and the largest individual transfers (from, to, amount, tx hash, block, time, pctOfSupply). Also includes RPC provenance metadata and an explanatory note.
Example use cases
Whale activity alert for trading bot
“Pull the token flows for the Base ERC-20 at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed over the last 30 minutes and tell me the top 10 net buyers and sellers — I want to know if any whales are accumulating or dumping.”
DeFi token launch monitoring
“Check the transfer activity for the token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base for the last 15 minutes — give me volume, number of active wallets, and the single largest transfers so I can see if there's unusual early activity.”
Post-announcement sentiment via flow data
“I just saw a big announcement for a Base token — can you look up the flow data for contract 0x4200000000000000000000000000000000000006 over the past 60 minutes with a limit of 25 rows and tell me whether net buyers or net sellers are dominating?”
Technical details
Endpoint
GEThttps://1gateway.dev/v1/onchain/base/token-flows?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need aggregated buy/sell flow intelligence for a specific Base mainnet ERC-20 token over a recent time window — particularly useful for identifying whale wallets, measuring buy/sell pressure, or detecting unusual transfer activity. Prefer this over raw RPC calls when you need pre-aggregated net buyer/seller rankings and volume summaries without writing custom indexing logic. Use when you need clean JSON output without paying for a full blockchain indexer subscription. Not suitable for historical data beyond 60 minutes or for non-Base chains.
Side effects
- 400 error if address is an EOA (externally owned account) rather than a contract — not charged
- 422 error if contract exists but is not an ERC-20 token — not charged
- No transfers in window returns empty buyer/seller/transfer arrays with zero volume
- Very busy tokens may return an incomplete window (window.complete=false) with coveredMinutes less than requestedMinutes
- Invalid address format (not matching 0x + 40 hex chars) returns validation error — not charged
