The USAspending Application Programming Interface (API)

The USAspending API (Application Programming Interface) allows the public to access comprehensive U.S. government spending data.

The data include spending on awards ( e.g. , who received federal contracts or grants, geographic breakdowns, agency breakdowns, and much more). The data also include account-level such as federal employee compensation. You can learn more about the data and the federal law that requires it to be publicly accessible (the DATA Act) at http://fedspendingtransparency.github.io .

Verifying this receipt

The hash above was computed as:

sha256( coalesce(url, '<no-url>') || '\n' || raw_content )

Anyone with a copy of the original document can verify the match:

  1. Take the URL field and the original document content.
  2. Concatenate url + '\n' + content and SHA-256 it.
  3. Compare to the SHA-256 row above.

Or POST the candidate content to /source/6119/verify and our server will compare for you:

curl -X POST https://www.goblinhouse.net/source/6119/verify \
  -H "Content-Type: text/plain" \
  --data-binary @document.txt
