# WorldCat Search API — Special Information for 3rd OCLC Research Software Contest Participants The WorldCat Search API contest offering provides search and retrieval of bibliographic records in WorldCat, along with information on related library locations. Use of this service requires a service key which can be requested by email. You must be a registered contestant and provide your contest ID when requesting a key. General information about the WorldCat Search API is available on the OCLC Grid Services wiki, including specific information on the API's search options. However, the following information governs contest participants' use of this service and supercedes the general information available on the wiki . ## WorldCat Data and Indexes The WorldCat Search API contest service key provides access to the default API service level, including the data and indexes listed below. OCLC Member libraries have access to a second level of service. However, only the default level is eligible for contest use. Contestants from member libraries who wish to consider using the API for the contest should only use the default level of their member key or request a contest key. Note that you must be registered for the contest in order to request a service key. Be sure to include your contest ID when you request a key. The contestant API key is set to allow 500 requests within 24 hours.
