Output

Macro dashboard Fed balance sheet tracker

Technical details
Endpoint
GEThttps://darklyenergized.com/api/v1/x402/series/cb_usd_walcl?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic, time-series access to Federal Reserve total assets (WALCL) denominated in USD, especially for macro analysis, global liquidity research, or dashboard integration. It is ideal for comparing Fed balance sheet data against other central banks (also available on the same platform) and when you need pagination, date-range filtering, or summary statistics in a single call. Prefer this over FRED directly when you want a paid-API abstraction with consistent output schema and staleness metadata.
Side effects
- Invalid date format (non-YYYY-MM-DD) returns a validation error
- Requesting a date range with no available data returns an empty data array
- Limit exceeding 10000 returns a schema validation error
- Network or upstream data source unavailability may return a 5xx error
- Payment failure (insufficient USDC) results in a 402 Payment Required response blocking data access
