How this service works

Fetch multiple computed series in one call (the sum of each series price)

Output

Returns time-series data for each requested series ID over the specified date range. Each series includes computed values (e.g. USD-converted central bank total assets, reserve balances, dark energy oscillator readings). If summary=true, returns aggregate statistics rather than full bar-by-bar data. The price charged equals $0.05–$0.10 per distinct series ID included.

Example use cases

Global liquidity dashboard data pull

“Fetch the Fed, ECB, Bank of Japan, and PBoC total asset series together from 2020-01-01 to 2024-01-01 so I can build a chart of global central bank balance sheet expansion.”

Dark energy oscillator with CB assets

“Get me cbdet, cbdeo, and wresbal_plus from 2022-06-01 to 2023-06-01 — I want to compare the dark energy signal against the Fed's reserve balance.”

Macro research snapshot with summary

“Pull a summary of the Bank of Canada, Swiss National Bank, and Bank of England total asset series from 2021-01-01 to 2023-12-31 — just the summary stats, not every data point.”

Technical details

Endpoint

POSThttps://darklyenergized.com/api/v1/x402/series/batch?utm_source=zero.xyz

When to prefer

Use this endpoint when you need data from two or more of the available central bank or macro liquidity series simultaneously and want to minimize API calls and payment overhead. It is more cost-effective than calling individual series endpoints separately when fetching 3+ series. Prefer individual series endpoints ($0.05 each) only when you need exactly one or two series. Use this batch endpoint for dashboard builds, multi-CB comparisons, or any workflow that joins global liquidity data across regions.

Side effects

Invalid or unsupported series ID returns 400 with list of valid enum values
Date range with no available data returns empty series arrays
Requesting more than 20 series IDs triggers validation error
Malformed date format (not YYYY-MM-DD) returns 400 bad request
Payment failure via x402 protocol returns 402 Payment Required
from date after to date returns invalid date range error
