Evidence-backed facts
- OpenAlex documents JSON research-graph access at https://api.openalex.org, with entity routes such as /works, /authors and /sources. ID-based filters avoid ambiguous names, and nested entity stubs require a separate read for full details. informative
- The API overview describes free trial access without an account or key, with an optional api_key query parameter. It directs clients to Authentication for detailed key and rate-limit rules. informative
- List responses contain meta, results and group_by. The documented page size defaults to 25 and is capped at 100; meta.count is the matching total, while meta.page and meta.per_page describe the returned page. informative
- Titles, abstracts and affiliation strings originate outside OpenAlex and are passed through unsanitized. The security guidance treats them as untrusted text and calls for output-appropriate escaping or equivalent safe handling. informative
