Search NASA technical reports.

Searches the NASA Technical Reports Server like its search page: title, authors, date, report type, NASA center, report number, abstract and link to the citation. Returns the first page of results (10 by default, up to 25) and the total number of matches.

Ask in plain words. Your agent finds this recipe and calls it:

“Search NASA technical reports.”

Read-only: it changes nothing on the site. No login needed.

Requests

sent from your browser, in order

1GET/api/citations/search?page.from&page.size&qThe site's own citations search API, read-only GET, the same call its search page makes. Results are JSON records with title, authors, dates and the citation id.

Parameters

from your agent

limitintegerHow many results to return, 1 to 25 = 10

querystringrequiredTopic or words to look for in NASA reports, e.g. 'propulsion', 'heat shield', 'Mars rover'

Returns

to your agent

itemsobject[]abstract, authors, center, date, downloads_available, report_number, report_type, title, url

querystring

totalintegerNumber of matching reports in the whole index

Where it can send

ntrs.nasa.gov

Anything else is blocked by the extension.

Reads from your session

Nothing. Your browser attaches the site's cookies by itself.

Used only in requests to the addresses on the left. Never sent to wield.run or your agent.

Checks

a run passes when

length(output.items) > `0`
length(output.items[?starts_with(url, 'https://ntrs.nasa.gov/citations/')]) == length(output.items)
length(output.items[?title != `null`]) == length(output.items)

Raw recipe

Served as canonical JSON from /api/v1/recipes/ntrs.nasa.gov/search-government, so its sha256 matches the ETag and the index.
