How this service works
Search Crossref scholarly metadata across journals, conferences, and books by query, no key. Returns matching works with DOI, title, authors, and publication. For AI agents resolving citations and enriching bibliographies.
Output

Example use cases
Resolving a citation in a research paper
“I have this partial citation — 'Attention is All You Need, Vaswani et al.' — can you search Crossref to find the full bibliographic record including the DOI, all authors, and the venue it was published in?”
Enriching a bibliography for a literature review
“I'm writing a literature review on CRISPR gene editing. Can you search Crossref for the most relevant scholarly works on that topic and return their titles, DOIs, and author lists so I can build out my bibliography?”
Verifying author publication history
“Can you search Crossref for papers authored by 'Yoshua Bengio' related to deep learning and return the titles, DOIs, and publication names for what comes back?”
Technical details
Endpoint
POSThttps://proxy.suverse.io/v1/data/suverse-crossref-worksWhen to prefer
Choose this endpoint when you need to search Crossref scholarly metadata without managing your own Crossref API key, especially in agentic workflows that resolve citations, validate references, or enrich bibliographies programmatically. Prefer it over raw Crossref API calls when you want a pay-per-use, keyless integration. Use it when you need DOI resolution or author/publication metadata for academic works across journals, conferences, and books.
Side effects
- Empty result set if the query is too specific or uses unusual terminology not indexed by Crossref
- Partial metadata if a work's Crossref record is incomplete (e.g. missing authors or abstract)
- Payment failure (402) if the x402 payment of $0.003 USDC is not processed
- Timeout or rate limit if the upstream Crossref API is under load
- Malformed request body causes a 400-level error
