Input

{
  "daysBack": 30,
  "maxResults": 30
}

Field	Type	Description
`daysBack`	number	How many of the most recent daily records to return, counting back from today. Treasury publishes on business days only. Default `30`, max `1825` (~5 years).
`maxResults`	number	Maximum number of daily records to return. Default `30`, max `100`.

Output

One record per business day, newest first:

{
  "date": "2026-08-14",
  "debtHeldByPublicUsd": 32200393497585.51,
  "intragovernmentalHoldingsUsd": 7733240968527.27,
  "totalDebtUsd": 39933634466112.78,
  "dayOverDayChangeUsd": -1181741731.59
}

dayOverDayChangeUsd is the change in total debt versus the prior business day in the same result set (null for the oldest record returned, since there's nothing earlier to compare against in that batch).

How it works

Direct calls to the official US Treasury Fiscal Data API (Debt to the Penny dataset) — no proxy, no key, no scraping. Public US government data, updated each business day.

Pricing note

Billed per lookup (one run), not per record returned — one charge whether you request 1 day or 100.
