How this service works
Recompute a draw and check sha256(server_seed)==commit. ?round=1&client_seed=s&nonce=1&min=1&max=100
Output
Returns the recomputed draw result along with the sha256 hash of the server seed and a boolean or status indicating whether that hash matches the original commit — confirming or refuting that the random outcome was pre-committed and untampered.
Example use cases
Audit a lottery round result
“I participated in round 15 of that provably fair lottery. My client seed was 'abc456', nonce was 3, and the range was 1 to 50. Can you verify the draw was legitimate and that the server seed hashes correctly to the original commitment?”
Catch potential house cheating
“I'm suspicious about the outcome of round 88 — can you recompute the draw for me? Client seed is 'faircheck', nonce is 1, range was 1 to 6, and I want to know if sha256 of the server seed actually matches the commit they published.”
Transparency audit for gaming platform
“Before I keep playing on this platform, can you independently verify round 200 was fair? Use client seed 'verifytest', nonce 5, range 1 to 100, and confirm whether the server seed's hash matches their original commitment.”
Technical details
Endpoint
GEThttps://pyfile-agent.taile3ff35.ts.net:10000/data/fair/verifyWhen to prefer
Use this endpoint when you need to cryptographically audit a provably fair random draw and confirm the house did not manipulate the outcome. It is the correct choice when you have a round number, client seed, nonce, and numeric range and want an independent recomputation that checks the sha256(server_seed) == commit invariant. Prefer this over manual hash computation or trusting the platform's own display.
Side effects
- Missing required query parameters (round, client_seed, nonce, min, max) result in an error response
- Invalid round number returns no matching draw data
- Mismatched sha256 hash indicates a tampered or incorrect server seed — not an API error but a negative verification result
- min >= max or invalid range values may return a validation error
- Network or payment failure returns HTTP 402 or 5xx
