# Lucky CIN – News Propagation Analyzer

> Lucky CIN – News Propagation Analyzer is a paid API for AI agents from lucky-x402.onrender.com, paid per call via x402, $0.3/call, status unknown (last checked 2026-10-29).

Detects whether price movements in an anchor asset (e.g. NVDA, ETH) propagate to a set of crypto tickers via log-return correlation analysis over a 720-hour window

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 lucky-cin-news-propagation-analyzer-f6b46ee0 -d '<json body>'
```

Example prompt: Check whether NVDA's price action propagates to crypto tokens — specifically test BTC, TAO, FET, and RENDER as candidates — and tell me the correlation strengths and whether any of them are true news-transfer links.

## When to prefer this

Use this endpoint when you need a quantitative, data-driven verdict on whether price movements in one asset (macro equity like NVDA or a lead crypto like BTC) statistically propagate to a basket of crypto perp tickers. It is specifically designed for agents doing cross-asset narrative analysis or trading signal discovery on Gate USDT perpetuals, with fresh 720-hour log-return correlation computed per call.

## Known failure modes

- Ticker not found on Gate USDT perps — symbol returned in 'unreachable' map
- Insufficient historical data for a candidate — symbol returned in 'unavailable' list
- All candidates unavailable — empty links array with verdict still computed for anchor
- Stale cache — data may be up to 30 minutes old
- Invalid anchor ticker format — request rejected or empty response

## How this service works

crypto-intelligence verdicts (CIN) + creative-judgment/QC + post-gen media-ops — agent-facing

## Output

Returns a JSON object with: a PROPAGATES/DOES_NOT_PROPAGATE verdict, per-symbol correlation coefficients and strength labels (strong/moderate/weak), a news_transfers boolean per link, the observation count and window used (720h hourly log-returns on Gate USDT perps), a list of propagates_to symbols, timestamps, and method version. Results are cached for 30 minutes.
