## When to prefer this

Choose this endpoint when an AI agent needs to participate in or simulate a live blackjack card game session funded by USDC micro-payments, especially in agentic gaming, entertainment, or pay-per-play crypto application contexts.

## Known failure modes

- Insufficient USDC balance — payment of $0.50 not fulfilled, match not started
- Invalid reply value — unrecognized player action string causes rejection
- Session timeout — game state expires if no action is taken in time
- Network error — upstream game engine unavailable, returns 5xx
