# CitePulse Journal Intelligence

> CitePulse Journal Intelligence is a paid API for AI agents from citepulse.theaslangroupllc.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-13).

Retrieves venue and journal intelligence for a given journal — including OpenAlex metrics, DOAJ status, APC data, and Tavily-grounded legitimacy signals — to help authors and agents evaluate where to submit or whether to trust a citation source.

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 citepulse-journal-intelligence-5f5d5233
```

Example prompt: Can you look up the journal 'PLOS ONE' for me — I want to know its OpenAlex citation and works count, whether it's in DOAJ, what the APC fee is, and what legitimacy signals exist before I submit my paper there?

## When to prefer this

Use this endpoint when an agent or author needs to evaluate a specific journal or venue before submitting a paper or trusting a citation source. Prefer this over the bibliography verification endpoint when the focus is a single venue's metrics and credibility rather than batch citation checking. Best suited for submission decisions, peer-review due diligence, or citation source evaluation.

## Known failure modes

- Journal not found in OpenAlex — returns empty or null metrics
- Invalid or unrecognized ISSN/name — returns error or no match
- Tavily grounding unavailable — legitimacy signals may be incomplete
- Payment not completed — 402 response requiring x402 payment before data is returned
- Rate limiting or service unavailability — returns 429 or 503

## How this service works

Venue/journal intelligence for authors and research agents deciding where to submit or whether to trust a citation's source — OpenAlex metrics (works, citations, DOAJ status, APC) plus Tavily-grounded, cited legitimacy signals. Never renders a bare predatory/legitimate verdict — evidence list + neutral framing only.

## Output

Returns OpenAlex bibliometric data (works count, total citations), DOAJ inclusion status, APC cost, and a Tavily-grounded list of evidence-based legitimacy signals with neutral framing — no bare predatory/legitimate verdict, just supporting evidence for the agent or author to evaluate.
