Example prompt: Pull the Fed drains (TGA + RRP combined) time series from Darkly Energized for the past 12 months so I can see how banking system liquidity has been trending — give me up to 500 daily data points starting from 2024-06-01 through 2025-06-01.

## When to prefer this

Choose this endpoint when you need granular, dated time-series data specifically for the combined Fed TGA + RRP drains as a liquidity indicator. Prefer it over generic Federal Reserve data sources when you want the pre-computed sum of both drains with an inverted-axis convention suited to liquidity analysis, and when you need flexible date range filtering, pagination, or statistical summaries in a single call.

## Known failure modes

- Invalid date format for 'from'/'to'/'after' parameters (must be YYYY-MM-DD)
- 'limit' out of range (must be 1–10000)
- Payment failure or insufficient USDC balance for x402 protocol
- No data available for the requested date range (empty data array)
- Stale data warning if source feed has not updated recently

## How this service works

Fed Liabilities (TGA + RRP) ($0.10): Sum of Treasury General Account (TGA) and Reverse Repo (RRP). These represent liquidity drained from the banking system. Axis is inverted by default so that rising values indicate improving liquidity conditions.

## Output

Returns a structured object containing the series ID, name, description, category, frequency, and an array of dated data points with numeric values (or null where unavailable), plus metadata including record count, data range, freshness status, last observation date, and optional pagination cursor for continued retrieval.
