# CortexAssay Emerging Technology Topics

> CortexAssay Emerging Technology Topics is a paid API for AI agents from cortexassay.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Returns a ranked list of scientifically emerging technology topics with growth metrics, momentum statistics, and acceleration data computed from open academic literature.

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 cortexassay-emerging-technology-topics-237783bb
```

Example prompt: Show me the top emerging technology topics right now — I want to see what's growing fast in the academic literature, including momentum scores and multi-year growth rates.

## When to prefer this

Choose this endpoint when you need quantitative, citation-backed evidence of which technology areas are scientifically emerging — not just trending in news or social media. Ideal for R&D strategy, investment research, academic benchmarking, or any use case requiring provenance-traceable, reproducible technology intelligence. Prefer over general web search or LLM knowledge when you need structured growth metrics, momentum statistics, and topic IDs from open academic data.

## Known failure modes

- Invalid properties filter string returns 400 or empty results
- No emerging topics matching filter criteria returns empty topics array
- Payment failure via x402 returns 402 Payment Required before data is served
- Stale scan data if endpoint is queried between weekly computation cycles
- Universe size may vary week-to-week as OpenAlex data updates

## How this service works

Machine-consumable research and technology intelligence computed from open data (OpenAlex, CC0). Pay per call with x402. Schemas, prices and provenance are machine-readable.

## Output

A JSON object containing a ranked array of emerging technology topics, each with name, rank, field, subfield, topic ID, 1/3/5-year growth rates, total works over 10 years, works in last full year, momentum statistic, 3-year acceleration, and decile growth ranking. Also includes scan ID, method ID, data-as-of date, computation timestamp, and universe size (number of topics evaluated).
