## 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 synapse-academic-search-c03ce9e7
```

Example prompt: Search for recent academic papers on transformer neural networks and give me the titles, authors, journals, and citation counts — I need peer-reviewed sources from 2022 or later.

## When to prefer this

Choose this endpoint when you need quick, pay-per-call academic paper lookups without API key registration, especially in automated agent pipelines operating on Base with USDC micropayments. Ideal for retrieving structured bibliographic metadata (DOI, authors, citations) rather than full-text content.

## Known failure modes

- Empty results if the query matches no indexed works
- Malformed or missing query parameter returns an error
- x402 payment failure if USDC balance is insufficient or Base transaction fails
- Rate limiting or timeout if the upstream academic data provider is unavailable
- Ambiguous queries may return loosely related or irrelevant papers

## How this service works
