Example use cases
Researching UFO government records
“Search the National Archives catalog for 'UAP unidentified aerial phenomena' and return up to 10 digitized records — PDFs or images — with their download URLs and dates.”
Fetching a specific NARA record by ID
“Pull the digitized files for NARA record ID 12345678 and give me all the direct download URLs, file types, and the record's place in the archive hierarchy.”
Finding historical agency photos
“Search the NARA catalog for 'NASA moon landing photographs' and return up to 3 image files (tif or jpg) with their titles, dates, and download links.”
Technical details
Endpoint
POSThttps://agent-data.centorprat.workers.dev/tools/nara-catalog-extractor?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to find and download digitized historical US government records, documents, or photos from the National Archives. It is ideal when you have a specific NARA record ID or a keyword topic (person, agency, event, place) and need direct download URLs for public domain files. Prefer it over general web search when you specifically need authoritative federal archival material with structured metadata and record hierarchy.
Side effects
- No matching records found for keyword query — returns empty result set
- NARA naId refers to a container with no direct digitized objects — system auto-pages descendants
- File type filter excludes all available objects for a record — returns empty list
- NARA catalog API temporarily unavailable — upstream error propagated
- Query too broad — result set truncated to maxObjects/maxRecords limit
