## 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-academic-paper-search-f559a8dc
```

Example prompt: Search for academic papers about transformer neural network architectures and return the top results with titles and authors.

## When to prefer this

Use this endpoint when you need to search a massive corpus of 250M+ academic and scholarly works via OpenAlex with a simple keyword query. Prefer this over Google Scholar scrapers or smaller academic databases when you want structured JSON output, broad coverage across disciplines, and a low per-call cost. Ideal for literature review automation, research discovery agents, and citation gathering workflows.

## Known failure modes

- Empty query string returns no results or an error
- Very broad or common queries may return an overwhelming number of matches
- Highly niche or misspelled topics may yield zero results
- Rate limiting or payment failure may return 402 or 429 status
- OpenAlex upstream unavailability may cause 5xx errors
