How this service works
Use this to check a draw independently: recomputes the SHA-256 of a revealed server_seed against its hash, and the numbers of a swoge-hmac-sha256-v1 draw, or the 52-card shoe of a SWOGE casino hand (scheme swoge-casino-shoe with its nonce). Price: $0.003 in USDC on Base or Solana, or $0.02 in USDG or $SWOGE on Robinhood Chain (tool price + settlement cost, minimum $0.02).
Output
Returns whether the server seed's SHA-256 hash matches the committed server_seed_hash, and whether the numbers or card shoe produced by the swoge-hmac-sha256-v1 or swoge-casino-shoe scheme match the claimed draw outcomes — confirming or refuting the fairness of the draw.
Example use cases
Auditing a multiplayer agent raffle
“Verify this raffle draw wasn't tampered with — the server seed is 'f3a9...', server seed hash is 'bb21...', client seed is 'player1nonce', scheme is swoge-hmac-sha256-v1, and the winning numbers were [3, 17, 42, 8].”
Checking a SWOGE casino hand shoe
“I just played a hand at SWOGE casino and want to confirm the 52-card shoe was generated fairly — the server seed is 'e7c2...', server seed hash is '91fa...', client seed is 'table9nonce', scheme is swoge-casino-shoe, and nonce was 5.”
Confirming a giveaway result between agents
“Can you independently verify this giveaway draw? The scheme is swoge-hmac-sha256-v1, server seed is '1d4b...', server seed hash is 'c3e8...', client seed is 'giveaway2024', and the drawn numbers were [2, 11, 35] with min 1, max 50, count 3.”

Endpoint
POSThttps://web-production-220a3.up.railway.app/agentic/call/fair_verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to independently audit or prove the fairness of a SWOGE platform draw, raffle, casino hand, or game outcome — especially in multi-party trust scenarios where players or agents need cryptographic assurance. It is the canonical verification tool for swoge-hmac-sha256-v1 and swoge-casino-shoe schemes.
Side effects
- Server seed does not match its committed hash — hash mismatch error
- Drawn numbers do not match what the algorithm would produce — verification failure
- Invalid or unrecognized scheme value — schema validation error
- Missing required fields (server_seed or client_seed) — 400 bad request
- Payment not settled — 402 payment required
