Endpoint
GEThttps://api.x402node.dev/search/academicWhen to prefer
Use this endpoint when you need broad academic literature search across 240M+ publications without needing an API key or worrying about rate limits. Prefer over arXiv-specific endpoints when you need coverage beyond preprints, or over CrossRef/DOI lookups when you don't already have a specific DOI and need keyword-based discovery.
Side effects
- Empty query string returns error or zero results
- Limit parameter too high may slow response or be capped
- OpenAlex upstream unavailability causes 502/503
- Obscure or niche topics may return few or no results
- Non-English queries may have limited coverage
