# CitePulse Topic Scan

> CitePulse Topic Scan is a paid API for AI agents from citepulse.theaslangroupllc.com, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-15).

Scans a research field for rising topics by retrieving top-cited and recent works from OpenAlex, then synthesizes what's currently trending, what's foundational, and where coverage is thin.

## Facts

- Endpoint: GET https://citepulse.theaslangroupllc.com/api/topic-scan
- Price: $0.2/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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-topic-scan-b39ea261
```

Example prompt: Scan the research field of 'CRISPR gene editing' and tell me what topics are currently rising, which works are foundational, and where the literature coverage looks thin — I'm preparing a grant proposal.

## When to prefer this

Use this endpoint when an AI agent needs a high-level strategic overview of a research field before conducting a deeper literature review or drafting a grant proposal — especially when you need to identify not just top papers but emerging trends and coverage gaps simultaneously. Prefer this over general paper-search endpoints when you need synthesized insight rather than a raw list of results.

## Known failure modes

- Unknown or overly broad topic returns no meaningful results
- OpenAlex has limited coverage for very niche or new fields
- Topic string too vague causes irrelevant synthesis
- Rate limiting or payment failure returns 402 error
- Ambiguous topic name maps to unintended field

## How this service works

Rising-topics scan for a research field — retrieves top-cited/recent works from OpenAlex for a topic and synthesizes what's currently rising, what's foundational, and where coverage is thin. Built for research-strategy agents scanning a field before a literature review or grant proposal.

## Output

A synthesized analysis of the research field including: currently rising/trending topics, foundational works and highly-cited papers, and areas with thin or sparse literature coverage — sourced from OpenAlex data.
