Bitcoin broadcast-timing decision feed for agents: next-block fee estimate sat/vB, fee TREND (rising/falling since last poll), broadcast verdict (broadcast now / wait / wait briefly), economy-tier savings %, recheck-in-seconds, mempool backlog, congestion tier, fee-spike flag, tip height, BTC spot. Poll each cycle to time a BTC broadcast and minimize fees — should I broadcast now? Decision feed, not raw Bitcoin Core RPC. Free teaser: GET /pulse/preview.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
