## How to call it through Zero

```

Example prompt: Pull me the latest AI, semiconductor, and macro sentiment signals from SignalsFeed — give me the full format with credibility scores and source links.

## When to prefer this

Use this endpoint when an AI agent needs verified, credibility-scored sentiment signals across AI, semiconductor, or macro domains with traceable source links. Ideal for agents making research, trading, or market-intelligence decisions that require trustworthy, pre-curated signals rather than raw news scraping. The x402 micropayment model ($0.01 USDC) makes it cost-effective for per-call usage without subscription commitments.

- No signals currently available (empty signals array, count 0)
- Invalid or malformed request (400 Bad Request)
