Expired Domain Opportunity Finder

Evaluate expired domain candidates for a specific niche. Score them on topical fit, historical activity level, history cleanliness, and redirect suitability. Output a conservative, explainable shortlist for human review.

Critical rule: Every recommendation must include BOTH a positive rationale (why_selected) AND a caution rationale (why_risky). Never output a bare score without explanation.

Conservative-by-default rule: When signals are incomplete or contradictory, lower the confidence level. Do not surface ambiguous candidates as strong opportunities. Missing data reduces confidence, never inflates it.

Anti-abuse rule: Never encourage unrelated redirects, PBN construction, or domain repurposing where the historical topic does not match the target niche. Read references/guardrails.md for the full anti-abuse policy.

Step 1: Setup Check

Check the environment before doing anything else.

Verify that curl and python3 (or python) are available:

curl --version > /dev/null 2>&1 && echo "curl: available" || echo "curl: MISSING"
python3 --version 2>/dev/null || python --version 2>/dev/null || echo "python: MISSING"

Check for an optional LLM API key for enhanced niche-relevance scoring:

echo "LLM_API_KEY: ${LLM_API_KEY:+set}"

If curl or python is missing: Stop. Tell the user: "This skill requires curl and Python 3.10+. Please install them and try again."

If LLM_API_KEY is not set: Continue. The skill will use rule-based scoring only (domain string matching, Wayback title analysis, keyword overlap). Note to the user: "Running in rule-based-only mode. Set LLM_API_KEY for enhanced niche-relevance scoring."

If LLM_API_KEY is set: The skill will use LLM-enhanced scoring for topical relevance analysis. This provides deeper contextual assessment of niche fit.

QA: State the scoring mode (llm-enhanced or rule-based-only) and confirm tools are available.

Step 2: Input Collection

Collect the required and optional inputs from the user.

Required:

target_niche (string): The core niche to evaluate against. Examples: "developer tools", "AI SaaS", "cybersecurity", "fintech".

Optional (ask only if not provided):

seed_keywords (array): Keywords to refine topical matching. If not provided, extract 3–5 keywords from the niche name automatically.
candidate_domains (array): Specific domains to evaluate. If not provided, prompt the user.
discovery_source (string): Where candidates came from — manual, expireddomains-net, external-feed.
min_snapshots (integer): Minimum historical snapshot threshold. Default: 10.
max_risk_level (string): low, medium, or high. Controls how aggressively risky candidates are filtered. Default: medium.
intended_use (string): rebuild, redirect, or either. Default: either.

If no candidate_domains are provided: Ask: "Please provide a list of expired domain candidates to evaluate. You can:

Paste domain names (one per line or comma-separated)
Provide a file path to a text file with one domain per line
Say 'example' to run with a built-in demo set for the 'developer tools' niche"

If the user says 'example': Use this demo set:

devtoolsweekly.com
codeshipnews.io
stackforgeapp.com
quickseorank.net
bestcheaphosting247.com
cloudbuildpro.dev
reactwidgetlib.com
megadealsshop.xyz

After collecting all inputs, confirm: "Target niche: [niche]. Evaluating [N] candidate domains. Scoring mode: [mode]. Intended use: [use]."

Step 3: Candidate Normalization

Clean and validate the candidate list before scoring.

python3 -c "
import sys, re

domains = '''CANDIDATE_LIST_HERE'''.strip().split('\n')
seen = set()
valid = []
invalid = []

for d in domains:
    d = d.strip().lower()
    # Strip protocols and paths
    d = re.sub(r'^https?://', '', d)
    d = d.split('/')[0]
    d = d.strip('.')

    if not d:
        continue

    # Basic TLD validation
    if '.' not in d or len(d) < 4:
        invalid.append(d)
        continue

    # Deduplicate
    if d in seen:
        continue
    seen.add(d)
    valid.append(d)

print(f'Valid candidates: {len(valid)}')
print(f'Removed (invalid/duplicate): {len(invalid)}')
for v in valid:
    print(f'  ✓ {v}')
for i in invalid:
    print(f'  ✗ {i} (invalid format)')
"

Replace CANDIDATE_LIST_HERE with the actual domain list from Step 2.

State: "[N] valid candidates after normalization. [M] removed (invalid/duplicate)."

If 0 valid candidates remain, stop and tell the user: "No valid domain candidates found. Please provide domain names in the format 'example.com'."

Step 4: Signal Collection

For each valid candidate, collect signals from free public sources. Run these checks sequentially per domain.

4a: Wayback CDX API — History Snapshots

Query the Wayback Machine for all historical snapshots. We use limit=100000 and explicit from/to parameters are intentionally omitted so that CDX returns snapshots from the full lifetime of the domain. The results are sorted ascending by timestamp (oldest first) so first_capture and last_capture are accurate:

curl -s "https://web.archive.org/cdx/search/cdx?url=DOMAIN_HERE&output=json&fl=timestamp,statuscode&collapse=timestamp:6&limit=100000" \
  | python3 -c "
import sys, json

try:
    data = json.load(sys.stdin)
    if len(data) <= 1:
        print(json.dumps({'domain': 'DOMAIN_HERE', 'snapshots': 0, 'first_capture': None, 'last_capture': None, 'status_codes': {}, 'years_active': 0}))
    else:
        rows = data[1:]  # skip header row
        timestamps = [r[0] for r in rows]  # already ascending (oldest first)
        statuses = [r[1] for r in rows]
        status_counts = {}
        for s in statuses:
            status_counts[s] = status_counts.get(s, 0) + 1
        first_year = int(timestamps[0][:4])
        last_year = int(timestamps[-1][:4])
        print(json.dumps({
            'domain': 'DOMAIN_HERE',
            'snapshots': len(rows),
            'first_capture': timestamps[0],
            'last_capture': timestamps[-1],
            'status_codes': status_counts,
            'years_active': last_year - first_year + 1
        }))
except:
    print(json.dumps({'domain': 'DOMAIN_HERE', 'snapshots': 0, 'error': 'wayback_api_failed'}))
"

Rate limiting: Wait 2 seconds between Wayback API calls to be polite to the service.

4b: Wayback Content Sampling — Historical Page Titles

For candidates with > 0 snapshots, fetch the most recent snapshot to extract the page title (used for topical relevance scoring):

curl -s -L "https://web.archive.org/web/LATEST_TIMESTAMP/http://DOMAIN_HERE" \
  | python3 -c "
import sys, re
html = sys.stdin.read()[:50000]
title_match = re.search(r'<title[^>]*>(.*?)</title>', html, re.IGNORECASE | re.DOTALL)
title = title_match.group(1).strip() if title_match else 'no title found'
# Extract meta description too
meta_match = re.search(r'<meta[^>]*name=[\"']description[\"'][^>]*content=[\"'](.*?)[\"']', html, re.IGNORECASE)
desc = meta_match.group(1).strip() if meta_match else 'no description found'
print(f'Title: {title}')
print(f'Description: {desc}')
"

Replace LATEST_TIMESTAMP with the most recent timestamp from Step 4a.

4c: RDAP Lookup — Registration Status

Use the cross-platform HTTP-based RDAP standard (replaces OS-dependent WHOIS). An HTTP 404 from RDAP means the domain is not registered (i.e. it is genuinely available or untracked) — that is distinct from a network failure. Handle both cases explicitly:

python3 -c "
import urllib.request, urllib.error, json

domain = 'DOMAIN_HERE'
try:
    req = urllib.request.Request(
        f'https://rdap.org/domain/{domain}',
        headers={'User-Agent': 'Mozilla/5.0'}
    )
    with urllib.request.urlopen(req, timeout=10) as response:
        data = json.loads(response.read().decode())

    registrar = 'unknown'
    created = 'unknown'

    for entity in data.get('entities', []):
        if 'registrar' in entity.get('roles', []):
            try:
                registrar = entity.get('vcardArray', [[]])[1][0][3]
            except Exception:
                pass

    for event in data.get('events', []):
        if event.get('eventAction') == 'registration':
            created = event.get('eventDate', 'unknown')

    print(json.dumps({
        'domain': domain,
        'status': 'registered',
        'registrar': registrar,
        'created': created
    }))
except urllib.error.HTTPError as e:
    if e.code == 404:
        # Domain has no RDAP object — likely unregistered or not in RDAP coverage
        print(json.dumps({'domain': domain, 'status': 'unregistered_or_no_rdap_object'}))
    else:
        print(json.dumps({'domain': domain, 'error': f'rdap_http_error_{e.code}'}))
except Exception:
    print(json.dumps({'domain': domain, 'error': 'rdap_lookup_failed'}))
"

4d: Domain String Analysis — Keyword Matching

Score keyword overlap between the domain name and the target niche / seed keywords:

python3 -c "
import re, json

domain = 'DOMAIN_HERE'
niche = 'NICHE_HERE'
seeds = SEEDS_JSON_HERE  # e.g., ['devops', 'ci/cd', 'code editor']

# Extract words from domain
domain_base = domain.rsplit('.', 1)[0]  # remove TLD
domain_words = re.split(r'[-_.]', domain_base.lower())

# Check niche words
niche_words = niche.lower().split()
all_keywords = set(niche_words + [s.lower() for s in seeds])

matches = [w for w in domain_words if any(kw in w or w in kw for kw in all_keywords)]
match_ratio = len(matches) / max(len(domain_words), 1)

print(json.dumps({
    'domain': domain,
    'domain_words': domain_words,
    'keyword_matches': matches,
    'match_ratio': round(match_ratio, 2)
}))
"

4e: Gemini LLM Niche-Relevance Assessment (if LLM_API_KEY is set)

If the LLM API key is configured, batch all candidates with their collected signals and ask for a contextual niche-relevance assessment.

Note: The request/response format below uses the Gemini API (generateContent format). It is not compatible with OpenAI-style endpoints without modification. If you use a different provider, you must adapt the JSON body and response parsing.

3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
