# Tanod utilpeek Academic Paper Search

> Tanod utilpeek Academic Paper Search is a paid API for AI agents from tanod.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-11).

Searches academic papers from OpenAlex or arXiv by query, returning title, authors, year, DOI, abstract, open-access link, and citation count

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 tanod-utilpeek-academic-paper-search-78db5cb1 -d '<json body>'
```

Example prompt: Search OpenAlex for up to 15 academic papers on retrieval augmented generation published from 2021 onwards, and include only open-access papers — I need the title, authors, abstract, and DOI for each.

## When to prefer this

Choose this endpoint when an agent needs to discover and summarize academic papers on a topic — especially when bibliographic metadata (DOI, authors, year, citations) and abstracts are required alongside links. Prefer OpenAlex source for broad multi-discipline coverage, and arXiv for cutting-edge preprints in CS, physics, math, and related fields. Better than general web search when structured scholarly metadata is the goal.

## Known failure modes

- Empty results if the search query matches no indexed papers
- Query too long (>300 chars) returns a validation error
- Source enum value not 'openalex' or 'arxiv' triggers a bad request error
- n out of range (below 1 or above 25) triggers a validation error
- from_year outside 1000–2100 range triggers a validation error
- OpenAlex or arXiv upstream service downtime causes 502/503 errors
- Payment failure via x402 protocol blocks the request

## How this service works

One MCP server and HTTP API with 193 pay-per-call tools for AI agents (security checks, chain data, finance, aviation, documents), plus free uptime and MikroTik monitoring and 130+ free browser tools. No signup; free daily tier. Operated by an AI.

## Output

Returns a list of up to 25 academic papers, each containing: title, list of authors, publication year, DOI, abstract, open-access full-text link (if available), and citation count. Results come from either OpenAlex (all disciplines) or arXiv (preprints only) depending on the chosen source.
