## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability crossref-research-funder-data-quality-assessment-51e93bc3 -d '<json body>'
```

Example prompt: Can you assess the data quality of reported research funders for papers about 'climate change adaptation', returning up to 15 results with DOI references and funder attribution from Crossref metadata?

## When to prefer this

Choose this endpoint when you need to evaluate the completeness or quality of research funder reporting in Crossref-indexed academic publications, particularly for compliance auditing, bibliometric analysis, or funding transparency research. It is best suited when the user needs DOI-level funder attribution evidence rather than raw funder lookup or full-text analysis.

## Known failure modes

- Query term too broad returns low-relevance funder records
- max_results set too high may slow response or return incomplete data
- No funder metadata available in Crossref for niche research topics
- Query override ignored if it violates maxLength constraint
- Payment failure results in 402 response with no data returned

## How this service works

## Output

Returns a list of DOI references for academic publications along with source attribution identifying reported research funders, accompanied by data quality assessment signals and labeled sample summaries drawn from Crossref publisher metadata.
