How this service works
Continuous Stake-Weighted Rollover (CSWR) pool on Base. Stake USDC, win a pool-scaled multiple or get a partial refund back. Every /v1/pool/play call is an independent event — no lobby, no batching. Payout always returns to the same wallet that signed the payment.
Output
Returns a JSON object with the play outcome (win or lose), stake and payout amounts in atomic USDC units, rake deducted, pool size before and after the play, the dynamic multiplier in basis points, solvency cap if applied, an on-chain payout transaction hash (or null on loss), and an ISO timestamp of settlement. The paying wallet address is also echoed back.
Example use cases
Micro-stake pool play test
“Place a 0.10 USDC stake on the Split Pool and show me the outcome — did I win, what was the multiplier, and what's the pool size now?”
Automated agent gambling loop
“Run a single play on the Split Pool with a 1.00 USDC stake and return the payout transaction hash and settlement time so I can log it.”
High-stake single round
“Stake 5.00 USDC on the Split Pool CSWR right now and tell me the exact payout I received on-chain and what rake was taken.”

Endpoint
POSThttps://split.compose.land/v1/pool/playWhen to prefer
Choose this endpoint when you want an instant, single-event, on-chain USDC stake-and-payout game on Base with no lobby or batching. It is ideal for autonomous agents running independent plays, testing pool dynamics, or building automated game loops where each call is self-contained and settled immediately to the calling wallet.
Side effects
- Stake amount outside allowed range (0.10–5.00 USDC) returns a validation error
- Insufficient pool liquidity may trigger a solvency cap reducing the actual payout below target
- On-chain payout transaction failure returns payoutError with a message and null payoutTxHash
- x402 payment not included or malformed results in 402 Payment Required before play is attempted
- Network or RPC issues on Base may delay or fail settlement
