## 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 aggregated-crypto-news-with-sentiment-scoring-bb579907
```

Example prompt: Pull the latest crypto news headlines about Ethereum — up to 20 results — and tell me whether the overall sentiment is bullish, bearish, or neutral.

## When to prefer this

Use this endpoint when you need sentiment-tagged crypto news from multiple major outlets in a single call, without building your own feed aggregator and NLP pipeline. Ideal for agents that need to quickly assess market mood for a specific coin or topic, especially when replacing manual polling of CoinDesk, Cointelegraph, Decrypt, and peers.

## Known failure modes

- No articles found for the given coin or query filter — empty results array returned
- Invalid coin ticker or unrecognized name — may return unfiltered or empty results
- limit out of range (above 30 or below 1) — returns 400 validation error
- Payment not processed or x402 auth failure — 402 response blocking access
- Upstream feed temporarily unavailable — stale or partial results possible

## How this service works

Aggregated crypto news with sentiment: deduplicated headlines from many major crypto outlets (CoinDesk, Cointelegraph, Decrypt, Bitcoin Magazine, The Block, CryptoSlate), each scored bullish/bearish/neutral by a crypto-tuned lexicon, optionally filtered by coin or query. One call instead of polling a dozen feeds and running your own NLP.

## Output

A list of up to 30 deduplicated news items, each containing headline, source outlet, published timestamp, summary, and a sentiment label (bullish/bearish/neutral) with score, sourced from CoinDesk, Cointelegraph, Decrypt, Bitcoin Magazine, The Block, and CryptoSlate.
