How this service works
knowledge graph construction: Reported research funders: Reported research funders on knowledge graph construction using Crossref publisher metadata. Returns DOI references and source attribution. Query can be overridden; sample summaries are labelled.
Output
A list of academic records related to the query topic, each including DOI references and reported research funder details sourced from Crossref publisher metadata, with sample summaries labelled and source attribution included.
Example use cases
Funding landscape for knowledge graph research
“Show me the reported research funders for the top 20 papers on knowledge graph construction — I want to see which organizations and agencies are backing this field, with DOIs included.”
Grant source discovery for a literature review
“I'm writing a lit review on knowledge graphs and need to know who funds this research — can you pull up to 10 recent papers and list their reported funders from Crossref?”
Funder attribution check for a specific paper cluster
“For papers related to knowledge graph construction, give me funder metadata and DOI references for up to 25 results so I can map funding sources to publications.”

Endpoint
POSThttps://market.datapackvibe.com/x402/signal-research-knowledge-graphs-funding-evidence?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need funder attribution and DOI references for academic papers on a specific topic, particularly when building or enriching a knowledge graph with funding evidence sourced from Crossref. It is especially useful for bibliometric analysis, grant landscape research, or academic data pipelines that need structured funder metadata at low cost per query.
Side effects
- Query returns no results if the topic is too niche or unsupported by Crossref data
- max_results exceeding 30 will be rejected with a validation error
- Missing or incomplete funder metadata in Crossref records may result in sparse output
- Payment failure (x402) if USDC balance is insufficient
- Timeout if Crossref upstream is slow to respond
