Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct agents have paid it, how recently, and for what. Merchant wallet: 0x1b21e9ee4b0175a9c0687ccf3bc3b878ea73766a curl -s 'https://api.roundhouseai.io/v0/merchants/0x1b21e9ee4b0175a9c0687ccf3bc3b878ea73766a' curl -s 'https://api.roundhouseai.io/v0/entities/0x1b21e9ee4b0175a9c0687ccf3bc3b878ea73766a/settlements?limit=50' 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.
