Web Remote Procedure Calls (RPCs)

BOINC projects export a number of Web RPCs for creating, querying and updating accounts and host records, and miscellaneous other purposes. These can be used by account management systems and credit statistics web sites.

BOINC's RPC mechanisms have the following conventions:

  • Each RPC is an HTTP GET transaction.
  • The input is the GET arguments, i.e. a string of the form
?param1=val1&param2=val2&...&paramn=valn

where param1 ... paramN are the parameter names, and val1 ... valn are the values. Parameter values must be URL-encoded (for example, using PHP's urlencode function).

  • The output is XML.
  • If the project's get_project_config.php file includes a <rpc_prefix> element, its content should be used as the URL prefix; otherwise use the project's master URL.
  • Optional values are shown enclosed in square brackets.
  • If an RPC fails, the returned XML document is
<error>
    <error_num>N</error_num>
    <error_string>xxx</error_string>
</error>

where N is a BOINC error number and xxx is a textual description. BOINC error numbers are in lib/error_numbers.h; common errors are:

-1: Generic error (error_string may have more info)

-112: Invalid XML (e.g., the preferences passed to am_set_info.php are invalid)

-136: Item not found in database (bad ID of any sort, or ID refers to an item not owned by the caller)

-137: Name is not unique. The EMail address or team name is already in use.

-138: Can't access database (treat same as -183)

-161: Item not found (deprecated; treat same as -136)

-183: Project is temporarily down

-205: Email address has invalid syntax

-206: Wrong password

-207: Non-unique email address (treat same as -137)

-208: Account creation disabled

-209: Attach failed. Perhaps due to invalid invitation code.

Create account

action

Create an account. If the project already has an account with that email address, and a different password, it returns an error. If an account with that email address exists and has the same password, it returns the authenticator. Otherwise the project creates an account and returns the authenticator.

If <opaque_auth> is included in the reply, all subsequent RPCs that reference the account must supply the given string as well as the authenticator.

URL
project_url/create_account.php
input
email_addr
email address.
passwd_hash
The MD5 hash of the concatenation of the user's password and the lower case form of their EMail address. The user password itself is never sent in an RPC call.
user_name
the user name.
[ invite_code ]
Invitation code if project requires invitation to create accounts.
[ team_name ]
optional name of a team to put user in.

example::

http://ralph.bakerlab.org/create_account.php?email_addr=user@example.com&passwd_hash=2ab548fae3162ccfa1a2d41a55557a92&user_name=CrunchAll

output

<account_out>
    <authenticator>XXX</authenticator>
</account_out>

Look up account

action
If passwd_hash is given and is correct, the user's authentication string is returned. This authentication string is required for many of the other RPCs. If no account with the EMail address provided exists, an error is returned.

If <opaque_auth> is included in the reply, all subsequent RPCs that reference the account must supply the given string as well as the authenticator.

URL
project_url/lookup_account.php
input
email_addr
email address
[ passwd_hash ]
The MD5 hash of the concatenation of the user's password and the lower case form of the account's EMail address.
[ get_opaque_auth ]
Return the opaque authenticator for the user if the project provides one.
examples
http://ralph.bakerlab.org/lookup_account.php?email_addr=user@example.com&passwd_hash=2ab598faf3160ccfa1a2d41a95557a92&get_opaque_auth=1
output
<account_out>
    [ <authenticator>XXX</authenticator> ]
    [ <opaque_auth>xxx</opaque_auth> ]
</account_out>

Set account info

action
Updates one or more attributes of the given account. If email address is changed, you must also change the password hash. If the project uses opaque_auth, then it will be returned on the reply.
URL
project_url/am_set_info.php
input
account_key
Authentication string of user account being changed. See create account RPC or lookup account RPC
opaque_auth
