Raven supports stablecoin-native agent payments through ACP: offering solana_verify_token, USDC-settled, 0.1 per job, escrowed. Hosted API keys by request; MCP local is free; holder-beta is key-gated.
Future rail (documented only, no integration yet): x402 — HTTP 402 + USDC pay-per-call, already settling 35M+ transactions on Solana ecosystem-wide. ACP remains the live agent rail.
Hard limits: not an investment product · no yield · no custody of agent wallets · Raven never initiates trades · never recommends buying or selling · ACP payment buys verification service only · set your own spend limits before calling paid tools · no recurring billing unless explicitly implemented and documented later.
