# NOVA Trend Deep Analysis

> NOVA Trend Deep Analysis is a paid API for AI agents from nova-demand-worker.vercel.app, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-11).

Performs a deep, multi-source trend analysis for a given query, with optional region and source filtering over a configurable time 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 nova-trend-deep-analysis-3c423703 -d '<json body>'
```

Example prompt: Do a deep trend analysis on 'AI agents' across the US and GB regions, looking at the last 48 hours, pulling up to 10 results — I want to know how many sources are confirming it and how fresh the signals are.

## When to prefer this

Choose this endpoint when you need a deep, cross-validated, multi-source trend signal rather than a simple keyword search. It is ideal when regional breakdown and source diversity metrics matter — e.g. validating whether a trend is geographically broad or concentrated, or confirming that multiple independent sources are reporting the same signal. Prefer this over shallow trend lookups when the freshness and cross-source confirmation of signals is important to the decision being made.

## Known failure modes

- Query too short or empty — validation error returned
- windowHours outside 1–168 range — schema validation failure
- limit exceeds 20 — rejected by schema
- regions array exceeds 20 items — rejected
- sources array exceeds 10 items — rejected
- Payment not completed via x402/USDC — 402 response blocking access
- No trend signals found for obscure query — ok:true but low counts
- Service unavailable on Vercel deployment — 5xx error

## How this service works

Machine-facing pay-per-call utility services using x402 on Base with USDC.

## Output

Returns a JSON object with ok status, gear identifier ('global-trend-buyer'), mode ('deep'), the original query echoed back, and an analysis block containing: regionCoverage (list of region codes covered), sourceDiversity (number of distinct sources), freshSignalCount (number of recent signals found), and crossSourceConfirmed (number of signals confirmed by multiple sources).
