Anchor a SHA-256 digest of delivered content plus the x402 settlement reference on Solana. Returns a permanent, publicly verifiable receipt (poll until outcome === "settled"). Costs 0.001 USDC via x402; if x402_payment_signature is omitted, returns the payment challenge instead (pay 0.001 USDC to the service address, then call again with the payment tx signature).
