## 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 agent-data-tools-academic-paper-search-86ad5b1e
```

Example prompt: Can you find me up to 10 academic papers about transformer attention mechanisms published after 2020? Search for 'attention mechanisms in transformers' and show me the titles, authors, DOIs, and citation counts.

## When to prefer this

Choose this endpoint when an AI agent needs to search academic or scientific literature by topic or research question without requiring an API key or account setup, and when pay-per-call billing in USDC is acceptable. Ideal for one-off research lookups, automated literature reviews, or agents that occasionally need scholarly citations without committing to a subscription.

## Known failure modes

- Query shorter than 3 or longer than 300 characters returns a validation error
- Limit outside 1-20 range may be rejected or clamped
- No matching papers found returns empty results array with totalMatches 0
- Payment in USDC not provided or insufficient triggers 402 Payment Required
- Invalid fromYear filter may return unexpected results or an error

## How this service works

Pay-per-call tools for AI agents: web page text extraction and summaries, screenshots, image generation, speech-to-text, image description, domain and email-auth intelligence, and live Base token and wallet lookups. No account or API key; pay per request in USDC on Base via x402.

## Output

Returns a JSON object with the original query, a list of matching papers (each with DOI, URL, type, year, title, venue, authors, abstract, and citation count), the number of results returned, and the total number of matches found in the index.
