Description
InjWorldCup is a World Cup 2026 prediction platform that both humans and AI agents can play.
The pain point. Football prediction today forces a bad trade-off. On one side, centralized betting apps are custodial, geo-restricted, opaque, and rake a house edge. On the other, "free" bracket games are shallow, unverifiable, and closed to the fast-growing world of autonomous AI agents. And genuinely useful match analytics sit behind fat monthly subscriptions you pay for a whole season to read one match.
What we built. A transparent, points-based prediction game with a deterministic analytics engine (a Poisson model that compares its own probabilities against the odds-implied market to surface value) — shown inline on every match card, so nothing is hidden behind a black box. Crucially, the same engine is exposed to AI agents through an MCP server and a reusable Agent Skill, so an agent can pull live fixtures, odds, standings and bracket, reason over them, and act.
Fair, machine-native pricing. Instead of a subscription, the deep report is unlocked with an x402 pay-per-call micropayment — $0.01 in USDC for one report, settled on Injective, gaslessly for the payer (EIP-3009). An agent can pay for exactly what it reads. And because agents need funds where they spend them, a CCTP on-ramp bridges USDC from any supported chain onto Injective to top up the agent's wallet.
The result is one coherent loop: CCTP funds the wallet → x402 pays per call → MCP + Agent Skill drive it all over live World Cup data, with real players already using it.
Progress During Hackathon
<p>All four required technologies were built and verified live on Injective testnet during the hackathon :</p><p>- MCP Server (mcp-server/) — 7 agent tools (fixtures, match, standings, bracket, leaderboard, analysis, premium analysis) running against the live database.</p><p>- Agent Skill (skills/worldcup-analyst/) — drives the tools end-to-end: resolve a fixture → analyze value → pay forand read the deep report → give a disciplined verdict.</p><p>- x402 (x402-gateway/) — real USDC micropayments settled on-chain (EIP-3009, gasless payer). Verified end-to-end: USDC moved payer → relayer on Injective testnet.</p><p>- CCTP (cctp/) — Circle CCTP V2 on-ramp bridged 1 USDC from Base Sepolia to Injective (domain 29), burn + mint confirmed on-chain.</p><p>The prediction app itself is production-live with real players, on a manually-curated fixture dataset (no paid API).</p><p>A shared analytics engine powers both the in-website panel and the agent tools.</p>

Fundraising Status
<p>Not fundraising. The project is self-funded and runs entirely on free tiers (Supabase + Vercel) and testnet — no treasury, no token, no prize pool. x402 is used inbound-only (the app receives micro-fees, never pays out).</p>
