Thanks for sharing.

It would be great if blockchain.info used cors on this call especially...
curl https://blockchain.info/uuid-generator?api_code=&format=json&n=2

Here is the start of a work-around:
Step 1 issue this command to start their server on your local machine
nohup blockchain-wallet-service start --port 3030 &
Step 2 generate uuids in advance and pass them to your javascript or python app
curl http://127.0.0.1:3030/api/v2/create?password=thepassword$$\&api_code=yourcode\[email protected]

You can now add a cors=true parameter to most requests if you need the header e.g.

http://blockchain.info/unspent?cors=true

Which API calls support CORS?

I can get the "Access-Control-Allow-Origin" header back with this:
Code:
curl -v -H "Origin: http://example.com" \
  -H "Access-Control-Request-Method: GET" \
  -H "Access-Control-Request-Headers: X-Requested-With" \
  -X GET \
  "https://blockchain.info/unspent?cors=true"

This does not respond with that header:
Code:
curl -v -H "Origin: http://example.com" \
  -H "Access-Control-Request-Method: GET" \
  -H "Access-Control-Request-Headers: X-Requested-With" \
  -X GET \
  "https://blockchain.info/rawaddr/1EJcR6wPdtjYp2WYo1XPYryv9zJE1e6XtU?cors=true"

Am I doing something wrong?

You could try to use corsproxy

Not sure about the load it can handle though.

It would be absolutely awesome if blockchain.info could support CORS:

Access-Control-Allow-Origin: *

It would allow client-side projects to access the blockchain.info API without having to resort to hacks like using YQL.
