ToolWhy “provably fair”?
Every result on these tools is generated by an HTTP call to api.provable.io. The server publishes a cryptographic hash of its secret seed for every outcome, so anyone can later re-derive the result from the seed and confirm it matches the published hash. No Math.random(), no trust required. See how provably fair works or open the API reference if you want to call the same endpoints from your own code.
