## 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-9b67ebee
```

Example prompt: Pull the latest premium AI and semiconductor signals from SignalsFeed — pay the $0.01 and give me up to 20 full signals published since yesterday, with their credibility scores and sources.

## When to prefer this

Use this endpoint when an AI agent needs structured, credibility-scored intelligence signals on AI industry developments, semiconductor markets, or macroeconomic trends. Ideal for agents doing research, market monitoring, or investment analysis workflows where verified sourcing matters. Prefer over raw news feeds or search APIs when credibility scoring and curated domain focus (AI/semis/macro) are required. The x402 micropayment model ($0.01 per call) makes it cost-effective for per-query agent workflows.

## Known failure modes

- Payment not completed or x402 handshake fails — returns 402 Payment Required without signal data
- Invalid UUID format in ids parameter — returns 400 Bad Request
- Invalid cursor value — returns 400 or empty result set
- since timestamp in wrong format — returns 400 Bad Request
- limit out of range (below 1 or above 100) — returns 400 Bad Request
- No signals match quality_status filter — 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

Returns a JSON object with a count, format indicator, and an array of signals. Each signal includes full content (for paid/premium), credibility score, source links, observation date, and topic tags. Free discovery returns teaser/partial signals; paid ($0.01 USDC via x402) unlocks up to 20 full premium signals per call. Also returns pagination cursor (next_cursor) and has_more flag for iterating through the full feed.
