SEO Checker API

One async API for SEO data — SERP, indexing, reputation, audits, competitors, and semantics.

One API, every SEO signal

The SEO Checker API exposes our SEO data services through a single, consistent interface: API-key auth, credit-based billing, and an asynchronous task model (submit a task, poll for the result). Learn the flow once and it works across every service.

curl -X POST https://api.seo-checker.com.ua/v1/serp/tasks \
  -H "Authorization: Bearer sk_live_your_key" \
  -H "Content-Type: application/json" \
  -d '{"keyword":"best running shoes","region":"us","device":"desktop"}'
# → 202 { "task_id": "58e6…", "status": "queued" }
