Procedure

Run python3 skills/scientific-knowledge/crossref-metadata-search/scripts/search_crossref.py --query-title "single-cell RNA-seq" --rows 3 --out skills/scientific-knowledge/crossref-metadata-search/assets/crossref_single_cell.json.
Inspect message.total-results and message.items.
Use returned DOIs as anchors for follow-up literature or provenance work.

Validation

Command exits successfully.
Output JSON contains message-type equal to work-list.
At least one item is returned for a common topic.

Failure modes and fixes

Empty results: simplify the title query.
Rate or service issues: retry with smaller --rows and a descriptive user agent.

Safety and limits

Metadata only; access to full content depends on publishers.
Respect Crossref polite-use expectations.

Examples

python3 .../search_crossref.py --query-title "spatial transcriptomics" --rows 2
