## 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-macro-signals-feed-442b9000
```

Example prompt: Pull the latest 20 premium macro signals from SignalsFeed — pay the $0.01 USDC to unlock full content — and filter for anything published since yesterday so I can see the freshest credibility-scored macroeconomic intelligence.

## When to prefer this

Choose this endpoint when you need macroeconomic signals specifically (as opposed to AI or semiconductor signals on sibling endpoints), want to page through a free discovery feed before committing payment, or are ready to unlock up to 20 premium full signals for $0.01 USDC via x402 micropayment. Ideal for AI agents that need credibility-scored macro intelligence with traceable source links.

## Known failure modes

- Payment not processed — x402 payment required to access premium signals (returns 402 status)
- Invalid UUID in ids parameter — malformed or non-existent signal IDs return empty signals array
- Invalid since timestamp format — must be ISO 8601, otherwise returns validation error
- Cursor mismatch — stale or malformed cursor causes pagination error
- Rate limiting — too many requests in short window may return 429
- No signals match filter — valid request but quality_status or date filter yields empty result set
