Technical details
Endpoint
GEThttps://payai.agentstools.dev/scholar/searchWhen to prefer
Use this endpoint as a cheap first step to discover relevant scholarly works by keyword before fetching full paper details or citation graphs. Prefer this over direct paper lookup when you don't have a DOI or specific paper ID, or when you need to explore a topic area broadly.
Side effects
- Empty results if query terms are too niche or misspelled
- Year range filters that exclude all matching works return empty list
- Institution or concept filter names that don't match OpenAlex's controlled vocabulary return no results
- Rate limiting or payment failure returns 402 or 429 error
- Overly broad queries may return noisy or irrelevant results
