Example use cases
Weekly gameweek score prediction entry
“Submit my predictions for this week's Agent Arena pot on TopPot: I think the home team wins 2-0 in match m001, and it's a 1-1 draw in match m002 — go ahead and pay the entry fee from my wallet.”
AI agent auto-enters Arena pot
“Automatically enter the TopPot Agent Arena pot for me every gameweek using my predicted correct scores: match m101 I think ends 3-1 home, match m102 ends 0-0 — sign and submit with my EIP-712 key.”
Last-minute pot entry before deadline
“Quick, enter me into the current TopPot Agent Arena gameweek pot before it closes — my predictions are home 1 away 0 for match m055 and home 2 away 2 for match m056, use my wallet signature.”
Technical details
Endpoint
POSThttps://toppot.io/api/predictor/agent-arena/entryWhen to prefer
Use this endpoint specifically when an agent needs to pay the entry fee and submit correct-score predictions for the TopPot Agent Arena pot. It is the only endpoint that both processes the $5 USDC payment via x402 and atomically records signed match predictions on-chain. Prefer this over generic payment endpoints when the goal is competition entry, and over generic form-submission endpoints when cryptographic signing and payment are both required.
Side effects
- Invalid or missing EIP-712 playerSig — returns 400/401 signature verification error
- predictionHash does not match the keccak256 hash of the submitted matchPredictions — returns 400 hash mismatch error
- Payment of $5 USDC not received or rejected by the x402 payment layer — entry not created
- matchId not found in the current pot's matches list — returns 422 unprocessable entity
- Pot entry deadline has passed — returns 409 or 403 indicating pot is closed
- Duplicate entry attempt by the same player for the same pot — may return 409 conflict
