What is the Keysearch API?

Keysearch offers a simple official GET API that returns keyword lists and difficulty scores.

Access is gated behind a paid Keysearch account and marked for internal use only (not for resale). It covers keyword-research data, not the full toolset.

How much does the Keysearch API actually cost?

Verify on docs

Keysearch publishes an API, but per-tier gating wasn't extracted automatically.

  • Most likely scenario: API access is either included in all paid plans, or it's gated to higher tiers and we need to verify on the live docs page.
  • Until verified, treat the question "which plan unlocks the API" as open. Don't budget on the assumption it's free with the cheapest paid plan.

What you can build with the Keysearch API

Three personas, three different shapes of build. Pick the row that matches how you actually ship.

SOLO DEV / FOUNDER

Glue Keysearch into your daily workflow

  • Pull a digest of ranking changes into your morning Slack
  • Trigger a one-off backfill when something looks off
  • Pipe data into your own SQLite for ad-hoc queries
Effort: A weekend, one Node or Python script
AGENCY / CONSULTANT

Sell Keysearch reporting at scale

  • White-label Keysearch data into client-branded dashboards
  • Run scheduled multi-account reports without logging into the Keysearch UI
  • Cross-reference with the rest of the client's stack (CRM, analytics, ad spend)
Effort: 1-2 weeks, hits multi-tenant auth quickly
IN-HOUSE ENGINEER

Production pipelines for Keysearch

  • Real-time sync into your warehouse on a cron
  • Custom alerts the dashboard's built-in alerting can't express
  • Backfill + idempotency handling for Keysearch data older than the dashboard exposes
Effort: Multi-week project, expect rate-limit tuning

Quickstart template

# Starter template — endpoint paths and SDK package names come from
# the Keysearch API docs: https://www.keysearch.co/api/documentation

curl -X GET "https://www.keysearch.co/<your-endpoint>" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Accept: application/json" | jq .

Template only. Endpoint paths, exact base URL, and auth header format come from keysearch.co/api/documentation.

Limits and gotchas

  • No OpenAPI spec — you write typed clients by hand or use a third-party generator on the docs HTML.
  • No official SDK detected. Plan on hitting the API directly with your HTTP client of choice.
  • Rate limits: always read the docs page before scaling — the published limit is usually lower than the practical one and overages can be expensive.
5/10

Agent-readiness verdict

Not agent-ready: Keysearch lacks an MCP server, public API, and any official integrations with Claude or ChatGPT. The tool has no documented API endpoints or SDKs, making it inaccessible to agent workflows that depend on programmatic access.
