v1.3.0 (2026-07)

AI-powered outreach campaigns (Beta)

New: Outreach — an AI agent that finds link-building prospects from your competitors' backlink profiles and runs the outreach for you, end to end.

6-step campaign wizard — describe your goal and your domain; an agent researches competitors, mines their referring domains for realistic prospects (mega-platforms and integration directories are automatically excluded), finds the right contact at each domain, writes personalized outreach copy, and pushes everything to your sending platform.
Choice of AI model — OpenAI or Anthropic, using your own API key.
Choice of email finder — Apollo or Snov.io for finding and verifying contact emails at each prospect domain.
Choice of sending platform — Smartlead or Lemlist.
Nothing sends automatically — every domain, contact, and email is reviewable and editable before you push a campaign live.

Beta — verify results before sending. Find it under Outreach in the dashboard.

v1.2.0 (2026-06)

Platform detection endpoints

Two new BuiltWith-style endpoints for platform and technology lookups across the Common Crawl graph:

/v1/platform-domains — every domain running a given platform (Wix, Shopify, WordPress, Squarespace, Framer, and 14 more), ranked by domain authority, with min_da/max_da/tld/sort filters. Billed at 1 credit per domain returned.
/v1/platform-trends — ranked adoption counts for every detected platform. Costs 1 credit.

Both are also exposed as MCP tools (get_platform_domains, get_platform_trends). Coverage spans the 19 platforms reliably detectable from CDN / image-host signals; for script-tag tools (analytics, CRM, payments) use the real-time /v1/tech-stack.

MCP server reliability

Fixed long-lived MCP connections idle-disconnecting on Cloudflare. The legacy SSE transport (/?apiKey=) lacked keep-alive heartbeats; all clients now connect via the /mcp HTTP streaming transport, which is stateless per request and unaffected by this issue. Update your MCP client config to /mcp if you're still using the old URL.

v1.1.0 (2026-05)

Real-time analysis endpoints

Five new endpoints that fetch live data rather than querying the crawl index:

/v1/page-seo — title, meta description, H1, canonical, OG tags, and robots directives for any URL
/v1/tech-stack — server, framework, and CMS detection from live HTTP headers
/v1/site-health — HTTPS, redirect chain, robots.txt, and basic crawlability signals
/v1/sitemap — sitemap discovery and full URL list parsing
/v1/crawl-history — historical crawl frequency and first-seen date

New link analysis endpoints

/v1/competitor-gap — domains that link to a competitor but not to you, ranked by authority
/v1/link-audit — health score, risk flags, anchor profile, and top/risky backlinks in one call

Authority scoring

/v1/backlinks and /v1/referring-domains now accept ?score=true to include a normalised authority score (0–100) for each linking domain. Costs 1 extra credit per call.

Official SDKs

Python SDK — pip install rankparse
Node.js SDK — npm install rankparse

Both SDKs cover all live endpoints with typed responses and built-in retry logic.

Welcome — sent after account creation with your starting credit balance and a first API call example
Purchase confirmation — sent after every credit top-up with amount charged and new balance
Payment failed — sent if a card charge is declined, with a link to retry
Low credits warning — sent when your balance drops below a threshold
Credits exhausted — sent when an API call is rejected due to zero credits
API key created / revoked — sent when a key is added or deleted

All emails come from hello@rankparse.com. Reply to any email to reach the team.

Performance

Repeat lookups for domain authority, tech stack, and page performance now return in under 50ms
Improved query reliability — transient errors are automatically retried with per-request timeout budgets
