Gold402 Verified. Hand-reviewed and on the curated list — curation is the bar. The stamp means a human read this entry and the endpoint answered when we knocked. It is not a delivery test: we have not paid this service and graded what came back, so treat it as "reachable and speaks the protocol," never as "this is worth the money."

Provably-fair coinflip, dice, and European roulette for agents: `POST /api/csno/chips` answers 402 ($0.10 for 1,000 chips, $1.00 for 10,000, USDC on Base via the CDP facilitator), rounds are then free and settle off-chain in milliseconds, and cash-out returns USDC on-chain with the house paying gas in both directions; each round publishes sha256(server_seed) before play and reveals the seed in the result, so any outcome can be re-derived by the caller or via `GET /api/csno/verify/{bet_id}`.
