RankParse delivers the full backlink graph, domain authority signals, and on-page SEO data as clean JSON. Billed per request, starting at $0.01. No subscriptions. No seat fees. No monthly minimums. Credits never expire. The problem Every serious SEO data provider is priced for enterprise dashboard buyers. Ahrefs, Semrush, Moz, and Majestic start at $129 to $499 per month and gate API access behind their highest tiers. For developers building tools, agencies running periodic audits, and AI agents doing competitive research, the pricing breaks before the workflow does. RankParse closes that gap. Same depth of data, restructured for code and agents, priced for how teams actually query it. What you can do with it - Pull every backlink and referring domain for any URL - Run competitor link gap analysis: which domains link to your competitor but not you - Score outreach prospects by domain authority before a single email goes out - Detect the full tech stack of any URL: CMS, frameworks, analytics, CDN, payments - Audit on-page SEO and Core Web Vitals at scale, programmatically - Track lost and gained backlinks between crawls - Run link intersect queries across multiple domains - Hand your AI agent a domain and return a full SEO brief in seconds - Build SaaS dashboards on top of real backlink data without reseller licences - Power outreach automation that finds the right inboxes at the right sites Three surfaces, one API key 1. REST API. Python and Node.js SDKs. Direct curl access. 60 requests per minute. OpenAPI spec for typed integrations. 2. Native MCP server. Connect to Claude Desktop, Cursor, ChatGPT, or any MCP-compatible client in 30 seconds. Agents call RankParse like any other tool, with typed arguments and structured output. Ask Claude: "Find 20 high-DA sites linking to stripe.com but not plaid.com." It runs the diff and returns the list. 3. Chrome extension. Inline backlinks, domain authority, and tech stack lookups on any page you visit. Zero code. 25 endpoints, one clean API Backlinks. Referring domains. Anchor text distribution. Domain authority. Tranco rank. Tech stack detection. On-page SEO audits. Core Web Vitals. Link intersect. Lost and gained links. Competitor analysis. Batch lookups in a single request. Every response is paginated JSON with the exact credit cost included, so spend is always transparent. Who it's for - Solo founders shipping SEO tools who can't justify a $499 monthly SaaS line item - Agencies running client audits at a fraction of the data cost - AI builders adding backlink and competitive intelligence to their agents - Developers automating outreach, link prospecting, and reporting - Anyone who pays enterprise prices for queries they run a few times a week The honest tradeoff RankParse refreshes its index quarterly, not daily. If you need intraday SERP tracking or real-time rank monitoring, Ahrefs and Semrush remain the right choice. For backlink research, competitor analysis, link prospecting, monthly audits, and agent-driven workflows, RankParse delivers the same data at a fraction of the cost. Pricing - 100 credits free on signup, no credit card required - 5,000 credits for $50 - Backlink lookup: $0.02 per call - Domain authority check: $0.01 per call - Volume discounts unlock at $80 and scale up from there - Credits never expire Get started in under a minute Sign up, claim 100 free credits, copy your API key.
