## 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 feednews-digest-3961dea3
```

Example prompt: Pull me a digest of the latest AI and security news from the past 48 hours, filtering for anything mentioning 'LLM' or 'vulnerability', and give me up to 50 results.

## When to prefer this

Use this endpoint when you need a fast, scored, deduplicated news digest across multiple curated RSS categories (ai, tech, security, finance, science, world, dev) or custom feed URLs, with optional keyword filtering and time-window constraints. Prefer this over raw RSS parsing when you want deduplication, relevance scoring, and summarization handled server-side. It is ideal for agent pipelines that need structured news data without managing feed polling infrastructure. Pay only $0.01 USDC per call via x402.

## Known failure modes

- Missing required 'sources' parameter returns a validation error
- Invalid feed URL in sources causes that feed to be skipped or returns an error
- No items match the keyword filter resulting in an empty items array with stats showing filtered_out count
- since_hours exceeding 2160 (90 days) rejected with schema validation error
- limit exceeding 100 clamped or rejected
- Upstream feed unavailable causes reduced feeds_used count
- Payment failure via x402 returns 402 with payment requirements before serving content
