Macro-liquidityFed-balance-sheetCentral-banksMacro-indicatorsMarket-data

Catalog of the macro liquidity series x402 serves (Fed net liquidity, global central bank balance sheets), with unit, source and update frequency ($0.01). Daily readings, not weekly: the Fed's weekly H.4.1 balance sheet is merged with the daily Treasury General Account and overnight reverse repo data, so the aggregate liquidity series update each business day instead of once a week.

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.
