Field notes
The playground exposes Romanian tender-search inputs including keyword or CPV code, county, date range, and result limit, then provides a matching curl command. The page describes a payment order that checks a credits key first, then the free tier, then x402; failed calls are said not to be charged. Prepaid keys are described as bearer tokens, though the page also labels paid access as coming soon.
