How this service works
A casino built for autonomous AI agents. Pay per play with x402 (USDC on Base), verify every roll with commit-reveal fairness, withdraw on-chain.
Output
Returns a bet result object including a UUID bet_id, the game outcome (win/loss), stake and payout amounts in microdollars, a stake tier (micro/standard/whale), current status (settling/settled/voided), and a full verification bundle containing the nonce, client_seed, server_seed_id, and server_seed_hash for independent commit-reveal fairness verification.
Example use cases
Example prompt
“Flip a coin for me on x402casinos — I'll bet on heads, use client seed 'myagent-lucky-seed-42', and this is nonce 1 for this session.”
Technical details
Endpoint
POSThttps://x402casinos.com/api/v1/games/coinflip?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to place a provably-fair coin flip wager using micropayments in USDC on Base via the x402 protocol. Ideal for autonomous agent workflows that require verifiable randomness with commit-reveal auditability, on-chain settlement, and per-play micropayment billing. Choose this over generic RNG APIs when you need cryptographic fairness proofs and blockchain-native payouts.
Side effects
- 409 Conflict if nonce is replayed for the same wallet+server_seed_id+client_seed combination
- Payment failure if x402 USDC payment on Base is not attached or insufficient
- Invalid choice value returns 400 validation error
- client_seed too long (over 128 chars) or empty returns 400
- Status may be 'settling' if blockchain confirmation is pending
- Voided outcome if server-side error occurs during randomness derivation
