The mailto parameter no longer raises the limit. A free key raises the budget to one US dollar a day. |

Notes
Academic works, authors and their affiliations (theses, papers, institutions by year). Lineage calls it without a key: one author search (10 credits of OpenAlex's own budget) and one filtered works list (1 credit) per node, each sent with the Lineage User-Agent and the contact address from LINEAGE_CONTACT_EMAIL when set. Responses are cached 6 hours per instance. On a server whose shared keyless budget is spent, OpenAlex answers 429 and the node is listed in skipped[]; Lineage never asks for or creates a key. OpenAlex data is CC0. Citations point at the work's openalex.org page, which OpenAlex serves to scripts.
