## How to call it through Zero

```sh
zero fetch --capability manylives-research-papers-search-3e36a25c
```

Example prompt: Can you search for academic papers about agent payments and micropayments, give me the top 5 results from 2020 onwards?

## When to prefer this

Choose this endpoint when an AI agent or researcher needs to programmatically discover academic literature on trading, crypto, AI agents, or finance topics — especially when open-access links and citation counts are important. It is particularly useful within the ManyLives trading agent ecosystem where grounding strategy decisions in peer-reviewed research is valuable. Prefer over generic web search when structured bibliographic metadata (DOI, venue, authors) is required.

## Known failure modes

- Missing required 'q' query parameter returns an error
- Empty result set if no papers match the query keywords
- Invalid 'since' year format may cause unexpected filtering
- Limit exceeding 25 is clamped or rejected
- Payment failure or insufficient USDC balance prevents access (x402 payment required)

## How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

## Output

A JSON array of paper records, each containing a DOI link, publication year, paper title, venue name, list of authors, citation count, and an open-access URL where available.
