## 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 omnicall-research-papers-search-09e7e75d
```

Example prompt: Search for academic papers and research on 'LLM agents' — pull results across arXiv, Wikipedia, and other scholarly sources in one shot, no API key needed, pay per call in USDC.

## When to prefer this

Use this endpoint when an agent needs to search academic and research paper sources without managing multiple API keys or subscriptions. Ideal for research-oriented agents that need broad scholarly coverage (arXiv, Wikipedia, news, etc.) in a single call with pay-per-use USDC pricing on Base/Solana, avoiding the overhead of integrating individual academic search APIs.

## Known failure modes

- Query string missing or malformed — returns 400 or empty results
- Payment not processed (x402 protocol failure) — returns 402 Payment Required
- Rate limiting or upstream source unavailability — returns 5xx error
- No results found for niche or misspelled query — returns empty result set
- Network timeout if aggregating multiple slow sources simultaneously

## How this service works

Multi-platform meta-search — web, GitHub, Hacker News, Stack Overflow, arXiv, academic papers, Wikipedia, news in ONE call. For research, dev-discovery, and knowledge agents. Unified search across 8 sources beats single-platform APIs. Keyless, pay-per-call USDC on Base/Solana, no API key, no signup.

## Output

A unified set of research paper results aggregated from multiple academic and knowledge sources (arXiv, Wikipedia, etc.), including titles, abstracts, and links relevant to the query term provided.
