Yes, baseURL seems to have changed once I posted.
I tried putting in each line. Your baseURL has new characters in it "" I put them in but nothing changed.

The problem line is:
String baseURL = "http://api.nytimes.com/svc/search/v1/article";
or
String baseURL = "http://api.nytimes.com/svc/search/v1/article";

But WOW – I tried something else which worked.
I hand typed EVERY CHARACTER back in and it solved the problem!!
It has something to do with me cutting and pasting from your tutorial!! Must be extra invisible characters.
I really appreciate your time and attention.
I am so excited about your work. Thank you for your tutorial. Best, Jilly

Hi Jer, I've tried that and it didn't change anything. I used:

import org.json.*;

String baseURL = “http://api.nytimes.com/svc/search/v1/article&rdqu...

String apiKey = “820151880ac5d2227033d9d1a48451cf:13:34125204”;

void setup() {

};

void draw() {

};

Hi,

The second }; at the bottom of the sketch is a typo - I've removed it from the post. Try it without that?

I am so grateful for your swift reply. Yes this is what I have and it did not run.
Let me also say that I never get these built-in methods " void setup() { }; " to happen automatically

At Step Two, this is what I run (I copied exactly what the tutorial has, then add my apiKey):

import org.json.*;

String baseURL = “http://api.nytimes.com/svc/search/v1/article&rdqu...

String apiKey = “820151880ac5d2227033d9d1a48451cf:13:34125204”;

void setup() {

};

void draw() {

};

As a result I get (I have truncated below the "unexpected" part):
processing.app.debug.RunnerException: unexpected char: ''
at processing.app.Sketch.preprocess(Sketch.java:1395)
at processing.app.Sketch.preprocess(Sketch.java:1194)

Hi Jer, I've tried all other user groups (NYT, Processing, Google) and to avail I am bothering you with this. I'm on a Mac OSX (10.5.8) and I've followed your tutorial up to Step Two, and this what happens. I get the red code with the error: " processing.app.debug.RunnerException: unexpected char: '' " I've re-checked the code and my api key a million times. Is it because I'm on a Mac I can't run it?

Hi Emily, I will try to look at this tomorrow – I don't get the error since my API key is whitelisted for tonnes of requests. If some of your queries are working before you get the error, the 403 is almost definitely coming because you are hitting the API too often. It may be that rather than using a loop, it would be better to hit the queries once per frame. I will try to rebuild this and see what I can figure out. Cheers, -Jer

Thanks for posting this! I'm getting the same error as Aaron and Ryan (at end of post); my query is:

String request = baseURL + "?query=Dan+Brown&begin_date=19900101&end_date=20090101&api-key=" + apiKey;
String result = join(loadStrings(request), "");

Any help would be great!

Hi TimesFan,

I will try to look into this over the next couple of days - I haven't played with the NYT code for a while!

The error is definitely coming from hitting the API too frequently. I know the delay() calls don't work because I remember trying them when I was having the same problem myself!

I'm having the same problem as Ryan. How would one check if URL is valid? or catch the 403 error. thanks
