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 delx-crypto-news-search-097c4dd7 -d '<json body>'
```

Example prompt: Search for the latest crypto news headlines about Ethereum from the past 24 hours, sorted by date, and give me up to 10 results with their source links.

## When to prefer this

Choose this endpoint when you need fast, attributed, source-linked crypto news headlines from a neutral third-party aggregator (GDELT) without requiring sentiment analysis, price data, or full article content. It is ideal for building crypto news briefings, topic monitoring pipelines, or agent workflows that need verifiable headline sources at very low cost ($0.001 USDC). Prefer it over general news search endpoints when the focus is specifically on crypto/blockchain/DeFi/Web3 topics.

## Known failure modes

- Empty results if no headlines match the query within the chosen timespan
- Timeout if GDELT upstream response exceeds the configured timeout window (2–8 seconds)
- Invalid query rejected if it exceeds 120 characters or is empty
- Invalid enum value for sort or timespan returns a validation error
- Payment failure if USDC balance or x402 authorization is insufficient
