> Provably-Fair Round Seed Reveal is a paid API for AI agents from pyfile-agent.taile3ff35.ts.net:10000, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).

Reveals the server_seed for a completed lottery/draw round so participants can independently verify that past draws were fair and unmanipulated.

## How to call it through Zero

```sh
zero fetch --capability provably-fair-round-seed-reveal-3ae76f25
```

Example prompt: Can you reveal the server seed for round 7 so I can verify the lottery draw was fair?

## When to prefer this

Use this endpoint when you need to cryptographically verify the fairness of a past draw on this platform. It is specifically designed for post-draw auditing of provably-fair lottery rounds by revealing the previously committed server seed. Choose this over generic hash or lottery endpoints when the goal is transparency verification of a completed round.

## Known failure modes

- Round ID not found or does not exist — returns error or empty result
- Round is still active and seed cannot yet be revealed — seed disclosure only available after round completion
- Invalid or missing round query parameter — malformed request error
- Seed not yet disclosed if operator has not closed the round

## How this service works

Reveal the server_seed for a round so anyone can verify past draws. ?round=<id>

## Output

Returns the server_seed (a cryptographic secret withheld during the draw) for the specified round, enabling anyone to reconstruct and verify the randomness used to determine the outcome of that lottery draw.
