## 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 agentshelf-crypto-news-feed-75c49e93 -d '<json body>'
```

Example prompt: Can you pull the 5 most recent headlines about Bitcoin from the major crypto news outlets — I want to see what's happening with BTC right now?

## When to prefer this

Choose this endpoint when you need fresh, deduplicated crypto headlines aggregated across the four major outlets (CoinDesk, The Block, Decrypt, Cointelegraph) in a single call. Prefer it over scraping individual news sites when you need cross-source deduplication, ticker-aware search (BTC automatically matches Bitcoin), and fast cached results. The sandbox endpoint at /v1/sandbox/crypto-news allows free testing before committing to paid calls.

## Known failure modes

- Invalid query string (fails regex pattern or exceeds 40 chars) returns a 400 error
- Limit outside 1-40 range returns a 400 validation error
- Upstream feed temporarily unavailable may return partial results or 503
- Payment not included or insufficient USDC returns 402 Payment Required (use /v1/sandbox/crypto-news for free testing)
- No matching headlines for the given query returns an empty array

## How this service works

Call when an agent needs deduped crypto headlines from CoinDesk, The Block, Decrypt, and Cointelegraph, newest first, with source links. Optional q (BTC also matches Bitcoin) and limit. Feeds are cached for a few minutes. Send JSON {"q":"BTC","limit":1}. Exact $0.001 USDC on Base. Try unpaid POST /v1/sandbox/crypto-news first.

## Output

A JSON array of deduplicated news items sorted newest-first, each containing the headline title, a source link/URL, the publication timestamp, and the originating outlet (CoinDesk, The Block, Decrypt, or Cointelegraph). Up to 40 items returned depending on the limit parameter.
