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.
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.
The pay-per-call setup is genuinely useful for smaller projects where a monthly plan would be overkill. One thing that would make adoption easier for me though, would be a sandbox or test mode with mock responses, since right now every "just trying it out" call costs real USDC and that adds friction when evaluating the API before committing to integrate it into a real workflow.
honestly the pay-per-call model is such a relief, i hate juggling api keys and monthly plans just to test something out. ran a quick real estate lookup and it just worked, paid a few cents in USDC and got my data back instantly.
Pay per call sounds refreshing, especially for agents that only need occasional lookups instead of a full subscription eating budget. One thing that would make it even more useful for me: a built-in usage dashboard or simple credit estimator in the response headers, so I can see cumulative spend per wallet without building my own tracking layer.
