Helius just taught its Solana API to dig for you.
Parsed Events Scan, live Nov. 3, walks any address's history server-side and returns only the matches — already parsed. Filter by program, instruction name, mint, or native SOL. Up to 20 programs in one call.
Their demo: 3,402 Pump.fun txs scanned for the 10 most recent creator-fee claims in 182 ms, for 14 credits. The old getTransactionsForAddress path for the same haul: 350 credits, before you even parse.
Default budget is 10,000 txs a request, 100 matches back. Enhanced Transactions stays in maintenance; this is the successor.
You used to page the haystack. Now you name the needle.
