About

I'm a solo developer building J-sey, a pay-per-call data API for AI agents and developers — covering real estate, company records, patents, forex, and blockchain data. No subscriptions, just USDC per request via the x402 protocol. Building entirely from Termux on Android. Also into blockchain infrastructure and AI systems.

J-sey Data API - Pay-per-call data API for AI agents, no subscriptions

J-sey is a pay-per-call data API — not another subscription-based service. Instead of API keys and monthly plans, each request is paid instantly in USDC via the x402 protocol. It covers real estate, company records, patents, court records, forex, clinical trials, and blockchain/wallet risk data across 10 EVM chains, all through one unified API built for developers and AI agents.
