## 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-commodities-signal-feed-0106455d
```

Example prompt: Pull me up to 20 premium commodity signals from SignalsFeed — the ones with full credibility scores and source links — paying the $0.01 USDC unlock, and filter to only quality_status=premium signals observed since January 1, 2025.

## When to prefer this

Use this endpoint when you need structured, credibility-scored commodity signals covering AI, semiconductor, or macro domains and want to pay per-call via x402 micropayments rather than a subscription. Ideal for AI agents that need to browse or paginate through the signal inventory for free first, then selectively unlock premium full signals by UUID for $0.01 USDC per batch of up to 20.

## Known failure modes

- Payment not processed — returns free teaser signals instead of full premium content
- Invalid UUID in ids parameter — may return empty signals array or partial results
- Invalid cursor — returns 400 error or resets pagination
- since timestamp in wrong format — returns 400 validation error
- limit exceeds maximum of 100 — returns 400 or clamps to max
- No signals matching quality_status filter — returns count:0 with empty signals array
- x402 micropayment failure — falls back to free discovery tier

## 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, a format indicator ('full' for paid, 'teaser' for free), an array of signal objects with credibility scores and source links, optional top_topics and top_signals summaries, a next_cursor for pagination, and a has_more boolean flag.
