## 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 voidfeed-ai-fact-feed-latest-ai-model-protocol-facts-61f40fcd
```

Example prompt: Pull the latest verified facts about new AI model releases and benchmark scores from VoidFeed — I want each fact to come with its source URL and confidence rating so I can trust the data.

## When to prefer this

Choose this endpoint when you need trustworthy, citation-backed facts about the AI model landscape — specifically recent releases, benchmark numbers, or protocol shifts — and accuracy provenance matters. It is preferable over general web search when you need structured, confidence-scored facts with source URLs rather than raw unverified web content. Best for agents that need to cite their sources or fact-check AI industry claims.

## Known failure modes

- Payment not provided or insufficient ($0.05 USDC required via x402 protocol) — 402 Payment Required
- No new facts available since last call — empty or minimal result set
- Rate limiting if called too frequently
- Upstream source verification failure causing reduced confidence scores or missing citations
- Network timeout if upstream citation sources are slow to respond

## How this service works

Returns verified, citation-backed facts about new AI model releases, benchmark scores, and protocol changes, each with source URLs and confidence.

## Output

A feed of structured fact objects, each describing a recent AI model release, benchmark score, or protocol change. Each fact includes a name, content type, tier classification, source URLs for citation, and a confidence score indicating how well-verified the information is.
