Keyword difficulty
with OpenClaw, one call, no subscription.
Drop keyword difficulty scoring into your OpenClaw agent as a single tool call. Keywords go in, difficulty scores come out — billed per successful call with no SEO platform subscription and no API key to manage. Each keyword check is one predictable charge that OpenClaw can enforce budget caps against.
Real OpenClaw agents that use difficulty as a gate.
Each pattern below is an OpenClaw agent with keyword difficulty registered as a single decision tool. The math works because the agent only spends when a score comes back.
Gate keyword selection before writing.
A content brief OpenClaw agent receives a topic, generates candidate keywords, and calls the difficulty tool per term to filter out unwinnable ones. Only keywords below the difficulty threshold reach the brief-writing stage. Per-call billing means the scoring step costs exactly what it checks — nothing more.
Map an entire cluster and find the gaps.
A strategy OpenClaw agent expands a seed keyword into a full topic cluster, scores every term for difficulty, and surfaces accessible opportunities — low-competition terms the client's domain can actually rank for. Budget caps keep the scoring step from running unchecked across large keyword sets.
Only build pages for terms that can rank.
A page-generation OpenClaw agent checks difficulty before writing. High-difficulty terms get queued for a link-building pipeline; low-difficulty terms trigger immediate page creation. The difficulty tool is one gate call — OpenClaw handles the branching logic.
Score competitor keywords and flag the gaps.
A scheduled OpenClaw agent scrapes competitor page titles, extracts keyword targets, and calls the difficulty tool per term to find ones the competitor ranks for that are still accessible. Surfaces gap opportunities on a recurring basis without a full SEO platform subscription.
SEO difficulty scores that fit OpenClaw exactly.
Register one tool, connect a wallet, and your OpenClaw agent gets a difficulty score for every keyword it evaluates. Idle runs cost zero. Failed lookups cost zero. Each score is one predictable charge that OpenClaw can plan against — that's what the tool model was designed for.
- Single OpenClaw tool

OpenClaw-specific questions.
If something below doesn't cover your case, ping us — we work directly with OpenClaw builders, no SDR funnel.
How does this register as an OpenClaw tool?
+
It's a single POST endpoint with a typed body — submit a keyword string, receive a difficulty score and label. Register it in OpenClaw the same way as any HTTP tool: endpoint, schema, price-per-call. OpenClaw uses the price to enforce budget caps and show users what each run will cost before it fires.
Does OpenClaw need a long-lived API key?
+
No. The endpoint accepts x402-signed requests, so OpenClaw pays per call from a connected wallet. No shared secret to leak in agent logs or rotate quarterly.
What happens when an OpenClaw run hits its budget cap?
+
The tool returns whatever it has scored so far and OpenClaw budget enforcement stops the next call. The agent can ask for more budget or proceed with partial scoring.
How does a difficulty score improve OpenClaw agent decisions?
+
A 0–100 score is a clean branching signal. OpenClaw agents can route low-difficulty keywords to immediate action (write, publish, target) and high-difficulty ones to a different lane (link-building queue, deprioritize). No ambiguity, no human judgment needed mid-run.
How is this different from giving OpenClaw a subscription SEO tool?
+
Subscription tools don't report a true per-call cost, so OpenClaw can't do real budget planning against them. This tool reports an honest cost per keyword scored — exactly what OpenClaw was designed to consume.
