Early access

Autonomous Agent & Developer Infrastructure

Qerin pays selected sources for research and shows payment evidence when a query succeeds. Direct x402 access and MCP paid queries are paused during early access.

Developer access

Direct API billing is paused while we finish automatic refunds for failed answers. API keys and MCP paid queries are also unavailable. The web app is open for early-access research: each user funds their own Qerin wallet, and their Qerin agent pays sources from it within limits they sign.

Multi-Chain Technical Matrix

Each user's Qerin wallet holds USDC on Base and Solana; paid sources settle on whichever rail the user's agent pays from. Qerin receipts are recorded on Base or BOT Chain.
