## 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 speer-cyber-defense-security-feed-0728333b
```

Example prompt: Pull the latest 20 items from the Speer Cyber Defense security feed so I can review recent CVEs and cybersecurity news.

## When to prefer this

Choose this endpoint when an AI agent or automated pipeline needs a real-time or near-real-time stream of cybersecurity news, CVE disclosures, or threat intelligence items, especially when micropayment-based pay-per-call pricing on Base or Solana is acceptable. Prefer it over scraping security blogs when you need structured, machine-readable feed data with a clear freshness timestamp.

## Known failure modes

- HTTP 503 returned when security analysis or feed retrieval fails — not billed
- Empty items array if no recent feed entries are available
- Payment failure if USDC balance is insufficient (x402 protocol rejection)
- Invalid query parameters (e.g. non-numeric limit) may return a 400 error
- Network timeout if the upstream feed source is unavailable

## How this service works

Cybersecurity micropayments API for AI agents — pay-per-call USDC on Base and Solana (x402 v2). Free utility services under /v1/free/* and gateway select under /v1/gateway/* (Public). Paid cybersecurity analysis, CVE/security news feeds, Base blockchain intelligence, network intel utilities, composite domain/URL reports, research, conversion, verification, and feeds. Failed security analyses are not billed (HTTP 503).

## Output

Returns a JSON object with a boolean 'ok' status field, an 'items' array containing cybersecurity feed entries (CVEs, threat news, advisories), a 'status' string, and an 'updatedAt' ISO 8601 timestamp indicating when the feed was last refreshed. Cost is $0.001 USDC per call; failed analyses return HTTP 503 and are not billed.
