Demo
About
NextBeat is a wire desk for onchain research. Pick an assignment, get a free quote, then buy the next investigation beat with dust HBAR on Hedera testnet via x402. Each beat fuses live The Graph protocol data with Hedera state—metered, paid, and ready for AI agents. The brief reasons across protocols instead of pasting raw GraphQL, so one paid request advances the investigation with a clear next step.
How it's made
TypeScript monorepo with shared quote math, an Express investigation service, and a desk UI. GET /v1/quote is free and metered; POST /v1/brief is gated by x402 via Blocky402 so agents pay dust HBAR on Hedera testnet. Each beat pulls Hedera Mirror transactions plus live The Graph query URLs and reasons across protocols instead of dumping GraphQL. Optional HCS receipts for audit. Desk and API ship as one Vercel deployment sharing SERVICE_PUBLIC_URL.
