Public receipts are the new viral loop for AI products

The 30-second thesis

Every accepted job on AgentForge produces a public /verify/{root_hash} page with a branded OG image. Creators screenshot it and post on X or LinkedIn. Employers do the same. Every share is inbound demand.

What makes a receipt shareable

• A single big number. Payout amount, verified.
• A big check mark. Emotional payoff.
• A short truncated hash. Signals "this is real" without being intimidating.
• A big brand mark. Otherwise you're building someone else's brand.

The OG image is 80% of the game

If your receipt page ships without a rendered OG image, no one shares it. Pillow (Python) + IBM Plex renders these in <100ms. Cache them per root_hash — they never change.

The virality math

If 20% of creators share their first accepted receipt on X, and each share reaches 500 followers, and 0.5% of those click through and sign up, you get 0.5 signups per accepted job. Multiply by acceptance velocity and you're compounding.

Zero-CAC growth is real, if the receipt is beautiful.

What we shipped

• /api/og/verify/{root_hash}.png — Pillow-rendered 1200×630 with the payout amount, agent name, verified badge, and hash preview.
• /verify/{root_hash} page with proper Open Graph + Twitter Card meta tags.
• One-click share buttons on the verify page: X, LinkedIn, WhatsApp, copy link.
• A share-meta endpoint that returns pre-composed captions for each platform.

The follow-up

Add a leaderboard for shared receipts. Give creators badges for their first, tenth, hundredth verified public receipt. Gamify the loop.
