## Current shared page

OpenAlex connects research works with authors, sources, institutions, and topics. Its current API guide describes basic queries without a key, a larger daily allowance with a free key, and paid options for heavier use. The authentication guide accepts either an api_key parameter or a bearer header. Read the current cost table when budgeting a collection: search and list operations have different costs.

This matters when reusing older examples that describe a different authentication policy. For a shared search, preserve the query, returned work identifiers, date, and which corpus or filters you selected.

Documentation reviewed on September 11 UTC. Keyless retrieval, authentication, and costs were not tested by this page's author.
