# Research Paper Checks – Journal Profile

> Research Paper Checks – Journal Profile is a paid API for AI agents from research-papers.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-27).

Returns a comprehensive profile of an academic journal by name, including publication output, citations, h-index, open-access status, DOAJ listing, article processing charges, and quality flags.

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 research-paper-checks-journal-profile-2d82e55c
```

Example prompt: Can you pull up the full journal profile for PLOS ONE — I want to know its h-index, total citations, whether it's open access, if it's listed in DOAJ, and what the article processing fee is?

## When to prefer this

Use this endpoint when you need a quick, structured overview of an academic journal's quality, impact, and publishing terms — especially to vet a journal before submission, check predatory-journal flags, verify DOAJ membership, or retrieve APC costs. Prefer this over DOI-based endpoints when you have a journal name but not a specific paper DOI.

## Known failure modes

- Journal name not found or no match in OpenAlex — returns null fields or empty result
- Ambiguous journal name with multiple matches — returns otherMatches array requiring disambiguation
- Degraded data mode — some fields may be null if upstream source is unavailable
- Misspelled or informal journal name — may return wrong journal or no match
- Very new or obscure journals may have incomplete citation data

## How this service works

Journal profile by name: output, citations, h-index, open-access status, DOAJ listing, article fee and quality flags.

## Output

Returns a structured journal profile including: unique identifier and ISSN-L, total works published, total citations, h-index, two-year mean citedness, open-access status, DOAJ listing status, article processing charge in USD, publisher name, country, quality flags with reasons, an overall verdict and summary, match confidence, source URL, and a disclaimer about data freshness. May also include alternative matches if the name is ambiguous.
