PumpPortal provides low-latency data sources and transaction building for the Pump.fun bonding curve and Raydium liquidity pools. The Lightning Transaction API sends transactions from an HTTPS request, while the Local Transaction API builds transactions the user signs and sends. The Data API is free for new token and migration streams; trade streams cost 0.01 SOL per 10,000 trades. Trading fees are 0.5% per trade for Local and 1% for Lightning, excluding network and bonding curve fees. The FAQ says PumpPortal never has access to a wallet in local mode and advises treating Lightning wallets as hot wallets.
