This workflow is illustrative on the Robinhood Chain deployment. Chat settlement has live proof. Marketplace checkout uses approved real APIs when enabled; media remains unavailable and creator sales still need live validation.
- Use the Playground or a compatible EVM x402 client for an enabled chat model.
- Review the exact USD quote and quote-bound WIF amount before authorizing.
- Keep the signed receipt returned by a completed paid chat request.
- Use approved marketplace listings for paid API calls or a funded mandate for agent payments.
// WIF deployment: chat-only paid surface
// Request a free quote, then authorize the exact x402 EVM challenge.
// Marketplace: /v1/market (when enabled). Owner-funded agent mandates are live.
