Backtest a list of pump.fun picks against the chain's own history
Backtest a list of pump.fun picks against the chain's own history: up to 500 picks (mint, time, size in SOL) filled at the PumpSwap pool 3 s after the mark (graduates only; curve picks are counted in skipped_not_covered), pump.fun fees by venue and tier, 145,000 lamports a side, dead coins in the sum ($2 a run; 202 with a job id, then GET /replay/{id}). Use to check a caller's record or your own rule before trusting it.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
