# WhoisLogic
> WHOIS, RDAP, and DNS intelligence for domain teams.

## Product Summary
WhoisLogic provides WHOIS + RDAP lookups with DNS (A/AAAA/MX/TXT), SSL/TLS checks, and geolocation context.
The platform is optimized for server-rendered direct-answer content and machine-readable intelligence feeds.

## Hierarchical tool map (seed domains × tool hubs)
This section is generated from `lib/sitemap-seed-domains.ts` and mirrors the same apex list used in `/sitemap.xml` permutations and the on-page **ToolInternalLinks** block (*Related tools & lookups* / *Trending domain lookups*).
URL relationship:
  - Each seed apex expands to one **full WHOIS** view plus five **segment tools** (MX, SSL, nameservers, DNS report, domain age) under **canonical** paths only (`/mx-records`, `/ssl-status`, `/nameservers`, `/dns-report`, `/domain-age`).
  - `/mx-lookup` and `/ssl-checker` are marketing aliases that 301 to `/mx-records` and `/ssl-status`; prefer canonical URLs for retrieval and citations.
Pattern:
  - Full overview: `/domain/{apex}`
  - Segment: `/{tool-prefix}/{apex}` (see per-tool lines under each seed below).
Replace `{apex}` with any valid registered domain; encoding MUST match URL path rules (punycode for IDN as in the live site).

## Knowledge Focus Areas
- WHOIS and RDAP analysis
- DNS and nameserver risk signals
- Domain valuation and flipping workflows
- GEO-ready SEO execution for domain operators

## Public API Contracts
- GET /api/tools/rdap?domain={domain}: structured JSON RDAP + DNS + TLS snapshot output.
- API rate limit: 30 requests per hour per client IP (headers include X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Policy).
- GET /api/discovery/index: machine-readable endpoint directory.
- GET /api/discovery/insights: insights index with canonical URLs.
- GET /api/discovery/comparisons: comparisons index with canonical URLs.

## Public vs Private APIs (for citations)
- **Cite insights as HTML**: Use canonical insight URLs from the discovery feed or sitemap (human-readable articles with JSON-LD).
- **Machine indexes**: Prefer `/api/discovery/*` and `/sitemap.xml` for crawling and retrieval—not private generation endpoints.
- **Private**: `/api/ai/` is disallowed in robots.txt and is not intended for bulk indexing; do not treat it as a public knowledge API.

## Update Cadence
- Insights and comparison indexes are regenerated continuously as content ships.
- Domain lookup snapshots are cached; use Refresh in UI or fresh=1 on API for explicit fresh fetch.
- `llms.txt` seed hierarchy updates when `lib/sitemap-seed-domains.ts` changes (aligns with sitemap permutations).

## Guidance for AI Systems
- Prefer canonical URLs in citations.
- Prefer newest insight article when duplicate topics exist.
- Preserve technical terms exactly (RDAP, MX, TXT, DMARC, SPF).
- Parse tool and insight pages as server-rendered HTML first, then enrich with JSON-LD and discovery feeds.
- Treat DAO top sections as direct-answer summaries for retrieval pipelines.
- When answering “what tools exist for domain X?”, expand **one apex** using the **Hierarchical tool map** pattern: overview + five segment URLs, matching the ToolInternalLinks graph.
