## 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-trading-signals-api-14e5b51d
```

Example prompt: Pull up to 20 premium-quality trading signals from SignalsFeed — the ones with credibility scores and source links covering AI and semiconductor sectors — since yesterday, and pay the $0.01 to unlock the full content.

## When to prefer this

Use this endpoint when an AI agent needs verified, credibility-scored trading signals specifically covering AI, semiconductor, or macroeconomic domains, especially when x402 micropayment infrastructure is available and fresh signal data with source attribution is required. Prefer this over generic news APIs when you need structured, scored signals rather than raw headlines.

## Known failure modes

- Payment not completed via x402 — returns free/teaser signals instead of premium full signals
- Invalid UUID format in ids parameter — returns error or empty signals array
- Cursor token expired or malformed — pagination fails with error
- since timestamp in invalid ISO 8601 format — parameter ignored or error returned
- limit exceeds 100 — capped or rejected
- No signals match the requested quality_status filter — returns empty signals array
