Keyword difficulty,
one call, no subscription.
Submit a keyword and get back a competitive difficulty score — without subscribing to Ahrefs, SEMrush, or any other SEO platform. Pay per call, no account required. Built for AI agents and developers who need keyword data as one step in a larger content or SEO workflow.
Keyword data for agents that don't want a subscription.
Four patterns, each using difficulty scores as one decision gate in a larger content or SEO pipeline.
Filter keywords before writing starts.
An AI agent generating content briefs checks difficulty before recommending a target term. Low-difficulty terms go into the brief directly; high-difficulty ones are flagged for link-building investment or replaced with alternatives. One API call per keyword — no platform subscription needed to run the filter.
Score entire clusters, find the quick wins.
A content strategy agent maps a seed topic to dozens of related keywords and scores each for difficulty to separate quick-win opportunities from long-term plays. Per-call billing keeps cost proportional to the number of keywords checked — not a flat monthly fee.
Only generate pages for winnable terms.
An agent generating landing pages at scale filters candidate keywords by difficulty score before writing. Pages only get created for keywords below a set threshold, preventing wasted content production on terms that won't rank without significant domain authority.
Find accessible terms competitors already rank for.
An agent scraping competitor page titles extracts keyword targets and checks difficulty scores to identify terms the competitor ranks for that are still accessible. Surfaces opportunities without needing a full SEO platform workflow or a shared team account.
Keyword difficulty without the platform tax.
One endpoint, one score per keyword. No Ahrefs account to create, no SEMrush subscription to justify to finance. Submit a keyword, receive a 0–100 difficulty score, continue your pipeline. Billing runs per call so a one-off audit costs nothing more than the keywords you actually checked.
- No SEO subscription
- Pay per keyword
- No account setup
- Pipeline-ready
The honest answers.
If something below doesn't cover your case, ping us — we answer directly, no SDR funnel.
What does the difficulty score represent?
+
A 0–100 score reflecting how competitive a keyword is in organic search. Higher scores mean stronger competition from high-authority pages; lower scores indicate more accessible ranking opportunities. The score synthesizes backlink competition, domain authority of currently-ranking pages, and content depth signals.
Do I need an SEO platform subscription?
+
No. This is a standalone endpoint. No Ahrefs, SEMrush, Moz, or DataForSEO account required. You call the API, you get a score.
How is this priced?
+
Per call. You pay for each keyword difficulty lookup. No monthly minimums, no prepaid credit deposits, no platform fee. A 10-keyword check costs ten calls.
Can AI agents use this autonomously?
+
Yes. The API supports x402 micropayments so agents can discover and pay for calls without human setup or credential management.
How is this different from DataForSEO or SpyFu directly?
+
Those require account creation and prepaid credit deposits before your first call. This endpoint works without any account — submit a keyword, pay per call via x402, receive a score. Zero onboarding friction for agent pipelines that need to start immediately.
What if I need to score hundreds of keywords?
+
Call the endpoint per keyword. Per-call pricing means high-volume scoring is cost-proportional — you pay exactly for what you check, with no overage tiers or credit bundles to manage.
