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 signalsfeed-ai-signals-feed-42a7a537
```

Example prompt: Pull up to 20 premium full signals from SignalsFeed for AI and semiconductor topics — use quality_status=premium and include topics — I'm okay spending $0.01 USDC to unlock them.

## When to prefer this

Choose this endpoint when an AI agent needs verified, credibility-scored signals about AI industry developments, semiconductor trends, or macro conditions and is willing to spend $0.01 USDC per call for up to 20 full premium signals. Prefer it over generic news APIs when credibility scoring and x402 micropayment-gated premium content are required. Use the free discovery mode (quality_status, since, limit, cursor) for browsing available signal inventory before committing payment.

## Known failure modes

- Payment of $0.01 USDC not processed — returns teaser/limited signals instead of full premium content
- Invalid or expired UUIDs in ids parameter — signals array returns empty or partial results
- Invalid cursor value — pagination fails with an error response
- since timestamp in wrong format — filter ignored or 400 error returned
- Requested limit exceeds 100 — capped or rejected
- No premium signals available at query time — returns empty signals array with count 0

## How this service works

SignalsFeed is a signals feed for AI agents: verified AI, semiconductor, and macro signals with credibility scoring, source links, and x402 micropayments. $0.01 returns up to 20 premium full signals.

## Output

A JSON object containing a count of returned signals, format indicator ('full' for paid, 'teaser' for free), an array of signal objects each with credibility scores and source links, optional top_topics and top_signals arrays, and a next_cursor for pagination with a has_more flag.
