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 x402stock-news-sentiment-api-6abeacbb
```

Example prompt: What's the current news sentiment for Nvidia over the past week — is coverage trending positive or negative, and can you show me the tone timeline?

## When to prefer this

Use this endpoint when you need structured, quantified news sentiment for any financial asset, company, macro topic, or public figure — especially when you need tone trends over time (hourly timeline) rather than just a headline score. Prefer this over generic social sentiment APIs when you want news media coverage specifically, backed by GDELT's global news monitoring. Ideal for AI agents making investment-adjacent decisions or summarizing how the press is covering a topic.

## Known failure modes

- Missing required 'q' parameter returns validation error
- Query string too short (under 2 chars) or too long (over 120 chars) fails schema validation
- Invalid timespan value outside enum fails validation
- No matching news coverage for obscure query returns empty or null tone values
- Payment failure via x402/USDC returns 402 Payment Required
- GDELT upstream outage may cause delayed or unavailable data

## How this service works

Global news attention and tone for any company, ticker, or topic, from the GDELT Project's worldwide news monitoring. Pass `?q=Nvidia` (required), `?timespan=1d|3d|1w|2w|1m|3m` (default 1w). Returns average and latest tone with a positive/neutral/negative label and trend, an article-volume timeline, and recent headlines. A media-sentiment read distinct from the Reddit/4chan feeds.

## Output

Returns a sentiment object with average and latest GDELT tone scores (roughly -10 to +10), a label (positive/neutral/negative), a trend direction (improving/worsening), a hourly tone timeline, an article volume timeline with total monitored count, and a list of recent articles with titles, URLs, domains, and publication times — all attributed to the GDELT Project.
