'Thin' client access to MSA data

Three URLs have been created to facilitate access to MSA data from devices like PDAs and cell phones. They are:

US Chess Member Lookup (

Member ID Search ( (Member Lookup with parameters in URL only.)

The 'Member Lookup' URL will give you the name, expiration date, status and published ratings for a Member ID, plus the member's FIDE ID and current FIDE rating, if available. The default is today's date, so it will return the current published rating for someone, but you can enter an earlier date. (You can also call it using the ID you want to look up, eg,

The 'Member ID Search' URL will let you search for Member ID's by last name (at least 2 characters required), plus an optional first name and state field.

The third URL is intended for automated queries and requires all data in the URL (using the 'GET' method.) The thin.php and thin3.php URLs will accept both the Member ID and a cutoff date as part of the URL, eg,;2006-08-01 will give the player's published ratings as of the August 2006 supplement (or earlier.)

US Chess reserves the right to limit access to member and tournament records from specific sites or during peak usage time periods.
