I wonder, if there is an api that doesn't require oAuth and access Key. If I just want to search for pins using developer's key and secret? Is it not possible.

PS:
I wrote this scraper in php for extract the pins from the json found in the pinterest search DOM.

It'd be nice to have something official from pinterest.

Is this still working cause I am getting Authorization failed error even though I am using fresh access token.
stdClass Object ( [status] => failure [message] => Authentication failed. [code] => 2 [data] => [error] => stdClass Object ( [message] => None ) )

26 Jan 2018, Not work
Pinterest still use v1 for their public APIs

I make this to crawl images with search query in Pinterest feed. Check it out.
