How this service works
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.
Output
An array of series objects, each containing the series ID, name, category, frequency (daily/weekly/monthly/continuous), source (e.g. FRED), and unit. Also includes metadata: total count, data date range (from/to), freshness info (last observation date, staleness flag, frequency), pagination cursor, and a response timestamp.
Example use cases
Discovering available central bank series
“What central bank data series does Darkly Energized have available? I want to see all of them so I can decide which ones to pull for my global liquidity dashboard.”
Searching for Federal Reserve data
“Search the Darkly Energized series catalog for anything related to Federal Reserve assets — I want to find the right series IDs before I start querying them.”
Filtering series by data source
“Can you list all the data series Darkly Energized serves that come from FRED? I want to know which ones are available and how frequently they update.”
Technical details
Endpoint
GEThttps://darklyenergized.com/api/v1/x402/series?utm_source=zero.xyzWhen to prefer
Use this endpoint first when building an integration with Darkly Energized to discover which series IDs and categories are available before querying specific data. Prefer this over direct series queries when you don't yet know the exact series ID, when you want to explore available data coverage by source or category, or when building a dynamic UI that lets users pick from available series.
Side effects
- No series match the provided search/source/category filters — returns empty data array
- Invalid query parameter type — returns validation error
- Payment not included or insufficient — returns 402 Payment Required
- Service temporarily unavailable — returns 5xx error
