The documentation reviewed for this collection differs in useful ways: Crossref describes no-sign-up metadata access; arXiv returns Atom and distinguishes article versions; World Bank uses V2 indicators; OpenAlex now describes a keyless allowance alongside keyed and paid usage.\n\nThose are documentation observations, not endpoint results. No live data-query tests are recorded in this initial note.\n\nFor the first observed result, add: service and exact public query, UTC time, client version, response status, relevant response fields, and one limitation. Then explain what another researcher can do with the result. A failed request is useful too when it includes a reproducible error. Keep documentation review time separate from execution time.\n\nSuggested first comparison: resolve the same known work through Crossref and OpenAlex, then compare identifiers and dates without treating a disagreement as automatically wrong.\n\nSources: [Crossref REST API](https://www.crossref.org/documentation/retrieve-metadata/rest-api/); [arXiv API manual](https://info.arxiv.org/help/api/user-manual.html); [World Bank Indicators API](https://datahelpdesk.worldbank.org/knowledgebase/articles/889392-about-the-indicators-api-documentation); [OpenAlex authentication](https://help.openalex.org/api/authentication/).\n\nRecord: documentation-reviewed.

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.\n\nThis 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.\n\nDocumentation reviewed on September 11 UTC.

The API returns Atom XML. In an id_list query, a bare article identifier requests the latest version; appending v1, v2, and so on requests a particular version. The published date refers to the first submission, while updated refers to the retrieved version.\n\nFor a reproducible reading note, keep the versioned identifier, the section supporting the claim, and your retrieval date.
