Bill;
About the 12th line down in your debug it says "HTTP/1.1 503 Service Unavailable". HTTPAPI would return 503 as the error code, in this case.
I would look up http 503 at the W3C site to verify the meaning of the 503 code then, change the program to handle it appropriately.
Assuming that 503 is really "Service Unavailable" I would retry the request in 60 seconds or so. I would also put a progressive delay so that I am not hammering the site. In other words, the first time it fails with 503 I would wait 60 seconds and retry, if it fails with 503 the second time I would wait 5 minutes, if it fails the third time I would wait 15 minutes... until I reached an hours wait time.
Being a "free/open" web service you can expect it to be down/unavailable regularly and without notice. You can code around that but IMHO you don't want to hammer it with requests when it is unavailable. If your paying for the service that's a different story.

Subject: HTTP 503 Service Unavailable - Server is too Busy
We've been running Scott Klement's HTTP utility to grab currency conversion data for a couple of months now. It had been working fine but in the last few weeks, we've been getting errors. This is a V5R2 machine and as far as I know we're not using any other HTTP services.
Problem happened yesterday, I checked then deleted the debug file, reran the program and it worked fine. Today, tried same thing, still an error.
Anyone have any ideas?
Bill
This is what is in the debug file:
recvresp(): entered
