How this service works
Provably-fair round commit: sha256(server_seed) before any draw. ?round=<id>
Output
Returns the SHA-256 hash of the server seed that was committed before the specified round's draw, allowing participants to later verify that the seed was not altered after commitments were made.
Example use cases
Pre-draw fairness verification
“Fetch the SHA-256 commit hash for round 12 before we select a winner — I need to share it with participants so they can confirm the server seed was committed before the draw happened.”
Lottery audit trail
“We ran a giveaway in round 5 and someone is questioning the fairness — can you get me the server seed commit hash for round 5 so I can prove it was set before the selection?”
Multi-round integrity check
“I'm building a transparency log — can you pull the commit hash for round 99 so I can record the pre-draw commitment and later verify it matches the revealed server seed?”
Technical details
Endpoint
GEThttps://pyfile-agent.taile3ff35.ts.net/data/fair/commitWhen to prefer
Use this endpoint when you need to retrieve a cryptographic pre-commitment (SHA-256 of the server seed) for a specific round before or after a provably-fair draw occurs. It is the companion endpoint to the actual winner-selection endpoint on the same host — call this first to record the commit, then call the draw endpoint, then verify the revealed seed matches the commit.
Side effects
- Missing or invalid round parameter returns an error or empty response
- Round ID that does not exist returns a not-found error
- Service unavailable returns a non-200 HTTP status
- Malformed round parameter (non-integer) may return a validation error
