Current network fee conditions -- gas price (ETH/Base/Arbitrum/Optimism/Polygon), sat/vB fee tiers (Bitcoin), or recent prioritization fees (Solana) -- useful for an agent about to construct a transaction itself. (2 paid endpoints on chainsscope.duckdns.org.)
Call via Rooms
Rooms resells calls to chainsscope.duckdns.org: you make one x402 payment to Rooms, Rooms pays chainsscope.duckdns.org from its own wallet and returns the answer with a signed Rooms receipt. Never charged when the call fails. No account or API key.
$0.012 per call, all in (chainsscope.duckdns.org's listed price $0.01 plus the Rooms margin; the 402 quotes the live price)

curl -i -X POST https://rooms.aurmada.com/x402/v1/broker/chainsscopeduckdnsorg -H 'Content-Type: application/json' -d '{"path":"/tools/fee-estimate","query":{}}'
Send {"path", "method", "query", "body"}: path is one of the paid endpoints below (default /tools/fee-estimate), query and body go to chainsscope.duckdns.org 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.
