Every plan gives you one pool of credits instead of separate verification and finding limits — spend them however your work needs.
1 credit
Checking a reference against the academic databases.
4 credits
Searching for and relevance-checking a real source to support a claim — more work per request, so it costs more.
Mostly verifying? Your credits go further. Mostly finding new sources? You'll use them faster — the pool is yours to split however you need.
No — the free plan works from pasted citation text, BibTeX, or RIS files. PDF parsing (uploading a manuscript or paper directly) requires the Pro or Bulk Verification plan.
Yes — API access is available on every plan, including Free, authenticated via an X-API-Key header. Usage draws from your plan's regular monthly credit pool. See the API docs for details.
