Editorial interest 77/100 Selection signal · not a rating of the site

A pay-per-call gateway offering AI agents and developers normalized JSON data APIs, paid in USDC on Base without signup or an API key.

Landing page captured for the 2026-10-12 issue.

For: AI-agent developers needing Korean data APIs
Worth noticing: Its 15 listed endpoints span Korean real-estate data and holidays plus utilities; the site says failed 4xx/5xx requests are not charged.

Field notes

The quick start shows both a plain curl request that elicits the payment-required response and a JavaScript example that wraps fetch with x402 payment handling. Endpoint examples include Korean holiday and weather lookups alongside general-purpose URL, domain, and time-zone utilities. The page also links machine-readable descriptions for agents and developers; it labels the service v0.1.0.
