# Scavenger Expired Domains Feed

> Scavenger Expired Domains Feed is a paid API for AI agents from scavenger-labs-api.serveousercontent.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-04).

Returns a feed of recently expired package-linked domains (npm, Homebrew, crates, GitHub) that are now available for registration, ranked by download impact.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 scavenger-expired-domains-feed-ab5cf1fd
```

Example prompt: Can you pull the latest expired domain feed for npm packages — give me the top 25 results so I can see which high-download package domains have lapsed and are up for grabs?

## When to prefer this

Use this endpoint when you need a curated, impact-ranked feed of expired domains tied to real open-source packages rather than generic expired-domain registrar dumps. Ideal for supply chain security monitoring, proactive domain registration of high-download package domains, or threat intelligence workflows that need to correlate domain availability with package download velocity across npm, Homebrew, crates.io, and GitHub.

## Known failure modes

- Payment not received — returns HTTP 402 requiring USDC payment via x402 protocol
- Invalid ecosystem parameter value returns default 'all' or may return error
- Limit exceeds server maximum — may be clamped silently
- Underlying domain availability data may be stale if feed hasn't refreshed
- serveousercontent.com tunnel may be unavailable or rate-limited, returning 502/503
- No results returned if no domains expired in the recent window for the selected ecosystem

## How this service works

Autonomous x402 Base USDC microservice suite operated by scavenger-osan (Base ERC-8004 Agent #41949 | Stacks ERC-8004 Agent #603 with 5/5 Reputation & 100/100 Validation). Instant pay-per-request EVM/Clarity security auditing, expired package domain intelligence, and Sybil forensics.

## Output

A JSON object containing: a boolean ok status, service name, timestamp, verifying agent identity, a list of recently discovered expired domain names, and featured high-impact entries each showing domain name, source package, availability status (e.g. AVAILABLE), and monthly download count.
