Markets Build Buy
markets_build_buyBuild an unsigned Panta buy transaction (Solana v0, base64, plus the raw instructions) for your own wallet to sign and broadcast. SiteCheck never signs, holds keys or custodies funds. Then report the signature to POST /api/markets/report (free). Price: $0.01 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.
