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.
I built J-sey solo, entirely from Termux on Android. I wanted a data API that AI agents could pay for per-request without needing API keys or subscriptions — so everything runs on the x402 protocol with USDC payments settled on-chain, instantly.
A dedicated sandbox mode with mock data would be really useful so I can prototype and test integrations without spending USDC on every call, especially when iterating on error handling for the wallet risk endpoints.
