How this service works
listed:true — OpenAPI pre-register shape. Discovery submit HOLD until Board origin list.
Output
Returns a JSON object with an 'ok' boolean, the skill name 'openalex-works', a 'charged' flag indicating the payment was processed, and a 'summary' field. The actual works data from OpenAlex is included in the response, covering fields such as paper titles, authors, publication venues, DOIs, open access status, and citation counts for matching scholarly works.
Example use cases

Fact-checking scientific claims
“Search for published studies about 'vaccine efficacy against COVID-19 variants' and return 5 results so I can verify a claim I read online.”
Discovering authors in a niche field

Endpoint
POSThttps://x402-v2-mint-openalex-works.vercel.app/v1/openalex-works?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need keyless, pay-per-use access to OpenAlex scholarly works data without setting up an API account. Ideal for agents that only occasionally need academic literature search and want to avoid credential management. Prefer this over direct OpenAlex API calls when operating in an x402-enabled payment environment or when you need a simple POST interface with automatic billing.
Side effects
- 400 Bad Request when neither 'query' nor 'search' field is provided — request is not charged
- No results found for highly specific or obscure queries
- Rate limiting or upstream OpenAlex API unavailability causing failed lookups
- Payment failure via x402 protocol preventing request from being processed
- Query or search string exceeds 400 character maximum length limit
