+# pumpdata sample: one UTC day of pump.fun and PumpSwap trades, failed trades kept
 
 One UTC day, **2026-10-15**, of every pump.fun bonding-curve trade and every PumpSwap trade in the pumpdata.fun
 archive, with the trades that failed on chain kept beside the ones that landed. It's read from the chain's own
 ledger, not an indexer's copy. Parquet, zstd, in shards of at most 500 MB. Not affiliated with pump.fun.
 
-From [pumpdata.fun](https://pumpdata.fun/?utm_source=hf&utm_medium=listing&utm_campaign=open): every pump.fun trade, ever, sold by the call to trading agents (base rates, wallet records, launch records, replays) in USDC over x402. Free daily base rates: [/public/baserate.json](https://pumpdata.fun/public/baserate.json?utm_source=hf&utm_medium=listing&utm_campaign=open) and [/today](https://pumpdata.fun/today?utm_source=hf&utm_medium=listing&utm_campaign=open).
