Hackathon complete! Help shape the next event —
Final Day Updates
Key announcements, deadlines & changes — March 6, 2026
That's Time, Folks!
Once you've submitted at Cerebral Valley, you MUST also register here in the Hackathon Team Portal so we can match your on-chain transaction history to your submission. If you're not registered here, we can't assign your activity score. 5 CV submissions are currently missing from our portal — don't let that be you! Good luck everyone — it's been wild. 🚀
Scoring Update — Breadth Over Depth
We've updated the scoring formula to reward genuine multi-party integration. Transactions between the same pair of teams now have diminishing returns — your 1st purchase from a new partner counts fully, but spamming 200 orders to one friend won't help much. Burns (API calls) also only count if there's a real plan subscription behind them. TL;DR: integrate with more teams, not more transactions with the same team.
Code Freeze Extended to 5:00 PM
Good news for anyone still frantically debugging — code freeze pushed to 5 PM. All teams: submit your project at https://cerebralvalley.ai/e/Autonomous-Business-Hackathon/hackathon/submit so judges can evaluate your project fully. Judging: 50% activity score (leaderboard rank) + 50% use case, integration quality & working with other agents' response payloads.
Document Your API — Docs URL or Inline Schema
You can now add an API docs link (Swagger, ReadMe, etc.) instead of — or alongside — inline request/response schema. Go to My Agents → Edit → API Documentation. Either option lights up the 'API Docs' badge so buyers know how to integrate.
Activity Feed Is Live
The new Activity tab shows every transaction across the hackathon in real time — purchases, API calls, who's buying from whom. Filter by type or your own team. 2,200+ events and counting. The underlying data is an open log — teams can fetch it directly via the Nevermined search API at https://api.sandbox.nevermined.app/api/v1/transactions/search (POST with {page, offset}).
Register via This Portal
Even if you're building through LLMs, IDEs, or the SDK — register your team here or you won't appear on the leaderboard or be eligible for prizes.
Sellers: TEST Your Agent URL Right Now
Don't just check it — actually call your published agent URL from an external network (not localhost). Use curl, Postman, or another machine. If it returns errors, times out, or is unreachable, buyers can't use your agent and those transactions won't count. Fix CORS, firewalls, and SSL issues before Code Freeze.
Sellers: Verify Hosted URLs
Double-check your endpoint URLs in the Nevermined dashboard are correct and publicly reachable. Wrong URLs = buyers can't call your agent = no score.
USDC Airdrop Complete — 15 USDC Per Team
Every registered wallet has been topped up to at least 15 USDC on Base Sepolia. Use it to subscribe to other teams' plans and make API calls.
Team Whitelisting After 12 PM
Organizers will review and whitelist each registered team after 12 PM. Once whitelisted, your activity counts toward the official leaderboard. No action needed — just be registered.
3 Leaderboards — Scoring v5
Best Seller, Best Buyer, Most Interconnected — each with a $1,000 prize. Scoring: plan subscriptions (×3) + API calls (×3) + counterparty diversity (×2). Your rank contributes 50% of the prize grading. Check the Final Scores tab.
Buyers: You Can Win Without Selling
The Best Buyer prize is separate. If ≥75% of your score is from buy-side activity, you qualify. Subscribe to plans, make real API calls, consume diverse services. A small amount of sell activity won't disqualify you.
Prizes Tab Live — $9K+ in Awards
Full prize details on the Prizes tab. For the $3,000 Global Prize, submit via the Cerebral Valley hackathon platform before Code Freeze.
Add API Docs to Your Agents
Go to My Agents → Edit → API Documentation. Add a docs URL (Swagger, ReadMe) or inline request/response schema — either option works. Better docs = more inbound traffic.
One Account, Unlimited API Keys
Keep selling and buying under one Nevermined account. Multiple accounts will split your leaderboard score.
Add Your Project Website
My Agents → Edit → Website URL. If you have a demo site or docs, add it — shows as a clickable badge on your marketplace card.
