MtGox API is weird.

They say we should authenticate by sending or login and password via POST method, but they give an example where they are in URL:

https://mtgox.com/code/getFunds.php?name=blah&pass=blah

I don't get it. It data is in URL, isn't that GET method?

I'm guessing they show URL parameters as shorthand notation, since POST was specified elsewhere in the documentation.

It should be a post.
I used to have a script mtgox.sh for that:
curl -d `cat credentials` https://mtgox.com/code/${1}.php

where the file credentials would contain:
name=username&pass=password

so you could do:
mtgox.sh getFunds

But lately, my script stopped working with:
curl: (35) Unknown SSL protocol error in connection to mtgox.com:443

I tried looking into it, but it didn't seem to work,
no matter if i change protocol version --sslv2 or use the --no-sessionid option,
which people suggested when this error occurs.

I guess mtgox SSL requirements changed somehow...

Indeed, I could connect with a command like:

$ read -s passwd ; wget -q --no-check-certificate --no-proxy -O - "https://www.mtgox.com/code/getFunds.php" --post-data="name=grondilu&pass=$passwd"

And I had my JSON string:

{"usds":0,"btcs":0}

This is pretty cool.

HAve you tried with www.mtgox.com instead of just mtgox.com? I think there is an issue about that.

www.mtgox.com gives the same error ???

Well, if it doesn't work with curl, at least it does with wget. See above.

However, you might need to use a SSL-compiled version. See docs.

Title: Re: mtgox API
Post by: purplezky on April 08, 2011, 11:10:55 AM

using wget gives the same SSL problem.
The strange thing is that connecting to the api worked fine last month.
Now when i connect from a server in the USA or from Europe, they both give the same error.
That's why i suspect that either curl and wget both got updated SSL libraries with an backwards incompatible SSL handshake (highly unlikely),
or something changed in the implementation of the SSL handshake at mtgox.com (more plausible).

Code:

Setting --check-certificate (checkcertificate) to 0
Setting --proxy (useproxy) to 0
Setting --output-document (outputdocument) to -
Setting --post-data (postdata) to name=username&pass=password
DEBUG output created by Wget 1.12 on linux-gnu.

hum... it worked for me.

What versions of wget and libssl do you use?

Mines are:

If it works with wget and not with curl that's because the CA mtgox used isn't in the certificate bundle that's included with curl. The CA bundle included with curl is notorious for being out of date.

If it doesn't work at all, my best guess is a misconfigured load balancer or poisoned DNS.

BTW, I haven't seen any equivalent of the "--no-check-certificate" option in curl's manual page.

"curl -k"

Title: Re: mtgox API
Post by: purplezky on April 08, 2011, 12:33:06 PM

the gentoo packages with given USE flags, is what i used to produce the above errors

Code:

[ebuild] dev-libs/openssl-1.0.0d  USE="zlib -bindist -gmp -kerberos -rfc3779 -sse2 -test"
[ebuild] net-misc/wget-1.12-r3  USE="debug ipv6 nls ssl -idn -ntlm -static"

I now tried to compile curl with gnutls to see if it makes a difference

Code:

[ebuild  N    ] dev-libs/libtasn1-2.9-r1  USE="-doc"
[ebuild  N    ] net-libs/gnutls-2.10.5  USE="cxx nls zlib -bindist -doc -examples -guile -lzo -test"
[ebuild   R   ] net-misc/curl-7.21.4  USE="gnutls* ipv6 ssl static-libs* -ares -idn -kerberos -ldap -libssh2 -nss -test -threads"

I tried the -k option to not check certificates since curl-7.21.4 ships without any certificate bundle on gentoo.

Code:

curl -v -k -d `cat credentials` https://www.mtgox.com/code/getFunds.php
* About to connect() to www.mtgox.com port 443 (#0)
*   Trying 69.64.54.59... connected
* Connected to www.mtgox.com (69.64.54.59) port 443 (#0)
* found 142 certificates in /etc/ssl/certs/ca-certificates.crt
* gnutls_handshake() failed: A TLS packet with unexpected length was received.
* Closing connection #0
curl: (35) gnutls_handshake() failed: A TLS packet with unexpected length was received.

same handshake which fails, but a more verbose error message.

Title: Re: mtgox API
Post by: purplezky on April 08, 2011, 12:49:38 PM

ah i finally found out what was going wrong:
the server has disabled SSLv2,
and if you don't specify to use SSLv3 with curl,
it looks like it's doing a weird SSL handshake.

Code:

curl --sslv3 -d `cat credentials` https://www.mtgox.com/code/getFunds.php
{"usds":0.22,"btcs":39.74}

:D

Thanks for all the advice.

Hi,

Sorry for not seeing this thread sooner, I see there's a bug here (when ServerName matches the host name, TLS protocol doesn't work anymore), I fixed it for now by not providing a hostname in the vhost (and I'll try to upgrade openssl to see if it fixes the issue)

If I want to do this more properly, i.e. using the MtGox certificate, anyone knows how I could do?

I've seen on the web that I can retrieve the certificate with:

openssl s_client -connect www.mtgox.com:443 -showcerts

but I see several certificates (I think it's a chain or something).

Any idea?

Attached the part where I try to check my funds (obviously MyName and MyPass are my correct username and password :)

Code:

   Set Req = New WinHttpRequest
   Req.Open "POST", "https://mtgox.com/code/getFunds.php", False

Since the change in march 2012 the API isn't accessible with username/password
but it seems to work with the API key.

But whatever I'm trying to get this in VBA, this doesn't work for me.. :-\

When replacing the name & password with API key doesn't work,
and the wiki (https://en.bitcoin.it/wiki/MtGox/API/HTTP) also isn't very helpful

Code:

 
Set http = CreateObject("MSXML2.ServerXMLHTTP")
http.Open "GET", "https://mtgox.com/code/getFunds.php", False
http.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
http.Send ""

Can someone please help me with this? :)
Rights at the MtGox website are checked, so that shouldn't be the problem..

Thanks in advance :)
