That would be me.

And there already is an API. How else ? This is Free Pascal !


If you look in the browser developer console when using that page,
you'll see there are 2 calls available which do return JSON.

for dropdown completion:

https://www.freepascal.org/docsearch/docsearch.cgi/list?t=contains&m=1&q=as
https://www.freepascal.org/docsearch/docsearch.cgi/list?t=contains&m=1&q=al

q is the query parameter. m=1 requests metadata. m=0 omits metadata.

For actual search there is

https://www.freepascal.org/docsearch/docsearch.cgi/search?m=1&q=equals

again, search term is in 'q'. m has the same meaning.

The JSON is straightforward.

But I will document the API.
