  description: >-
    Live Robinhood Chain deployment: chat requests are paid per call in WIF
    using x402 exact EVM/Permit2 on `eip155:4663`. Free model discovery and
    quotes are available. WIF is an 18-decimal ERC-20. Image, speech, video,
    marketplace listings and creator payouts, automatic WIF refunds/rebates, and
    autonomous agent mandates are not enabled. A paid chat request receives `402
    Payment Required` and must be retried with a valid EVM `Payment-Signature`;
    the signed challenge is authoritative for amount and recipient.
