List the supported units and their metadata (abbreviation, measure, system, singular/plural names), optionally filtered to a single measure — a discovery endpoint for choosing valid `from`/`to` values. (2 paid endpoints on unit.openverbs.com.)
Call via Rooms
Rooms resells calls to unit.openverbs.com: you make one x402 payment to Rooms, Rooms pays unit.openverbs.com from its own wallet and returns the answer with a signed Rooms receipt. Never charged when the call fails. No account or API key.
$0.003 per call, all in (unit.openverbs.com's listed price $0.002 plus the Rooms margin; the 402 quotes the live price)

curl -i -X POST https://rooms.aurmada.com/x402/v1/broker/unitopenverbscom -H 'Content-Type: application/json' -d '{"path":"/v1/list","query":{}}'
Send {"path", "method", "query", "body"}: path is one of the paid endpoints below (default /v1/list), query and body go to unit.openverbs.com as given. Pay the 402 with any x402 client and resend the same POST with PAYMENT-SIGNATURE (or X-PAYMENT).
New to paying per call? x402 for agents explains the 402 → pay → retry loop.
