How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object with the OpenAlex work ID, DOI, full title, publication year, list of authors (with their OpenAlex author IDs and names), citation count, open access status (is_oa, oa_url, oa_status, any_repository_has_fulltext), and source metadata including provider, license, and cache timestamps.
Example use cases
Citation count check for literature review
“I'm doing a literature review and need to know how many times OpenAlex work W2741809807 has been cited and who the authors are — can you fetch that?”
Open access verification for a known paper
“Can you check if the paper with OpenAlex ID W3128349626 is available open access, and if so, what URL I can use to read it for free?”
DOI resolution from OpenAlex identifier
“I have an OpenAlex work ID — W2741809807 — and I need the DOI and publication year so I can add it to my reference manager.”
Technical details
Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/research/openalex-work?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a specific OpenAlex W-identifier and need authoritative structured metadata for that single work, including open access status, citation count, and author details. Prefer this over general web search when you need machine-readable bibliographic data cached and served at low latency with a fixed $0.003 cost. Ideal for enriching citation graphs, validating references, or checking OA availability programmatically.
Side effects
- Invalid W-identifier format (must match ^W[0-9]+$) returns a validation error
- Work not found in OpenAlex returns a 404 or empty result
- OpenAlex upstream API downtime causes fetch failure
- ID exceeds 30-character maxLength limit
- Missing required 'id' query parameter returns a schema validation error
