Videos

Description

This demo shows Hash PayLink’s 0G-powered agentic payment loop: a user pays through Hash PayLink, the payment is archived to 0G Storage and anchored on 0G Mainnet, then an AI agent verifies the 0G proof before unlocking a paid response.

Flow: PayLink payment -> 0G archive -> /api/agent-verify -> paid AI access unlocked.

Progress During Hackathon

<p>During the hackathon, we implemented the 0G payment proof layer for Hash PayLink.</p><p> Key progress:</p><p> - Integrated 0G Storage for permanent payment record archiving.</p><p> - Deployed PayLinkArchive on 0G Mainnet.</p><p> - Added dashboard 0G proof badges for archived payments.</p><p> - Built /api/agent-verify for trustless payment verification.</p><p> - Built /api/agent-ask for payment-gated AI responses.</p><p> - Extended the Telegram agent flow so paid AI access can verify payment before responding.</p><p> - Updated documentation, README, and demo flow for judges.</p><p></p><p>The result is a working agentic payment loop: PayLink payment -&gt; 0G archive -&gt; agent verifies -&gt; AI access unlocked.</p>
