Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 saylor-innovations-geo-datasets-search-639eb9c7
```

Example prompt: Find me NCBI GEO gene expression datasets related to Alzheimer's disease — give me up to 10 results with their accession IDs, organism, study type, and any linked PubMed papers.

## When to prefer this

Use this endpoint when you need to discover and retrieve structured metadata about gene expression studies from NCBI GEO — particularly when searching by disease, gene, tissue, or organism. Prefer this over manual NCBI searches when an agent needs machine-readable GEO series metadata including sample counts, platform details, and PubMed links in a single call. This is ideal for bioinformatics research assistants, literature review pipelines, and genomics data discovery workflows.

## Known failure modes

- No datasets found for obscure or misspelled query terms — returns empty datasets array
- Limit parameter outside 1–25 range may be ignored or clamped to defaults
- NCBI GEO upstream API unavailability causing failed or incomplete responses
- Overly broad queries may hit the result cap and miss relevant datasets
- PubMed IDs or BioProject fields may be null for older or incomplete records

## How this service works

Find NCBI GEO gene expression series by topic - accession, title, summary, organism, study type, sample count, platform and linked PubMed IDs

## Output

Returns a JSON object containing the interpreted query string, data source label, total match count, number of items returned, and an array of GEO series records each with: accession ID, canonical URL, title, summary, organism, study type, platform name, sample count, publication date, BioProject accession, and linked PubMed IDs.
