Click Get Started on the Starter or Pro card, pay with Stripe, and your personal API key appears on the checkout success page immediately after payment. No email wait, no manual provisioning. The free tier does not require an API key at all — you can start using the API right now.
All plans include every public endpoint: the eight classic diagnostics (DNS, SSL, HTTP headers, WHOIS, redirect checker, status, email validator, tech detect), the AI Readiness suite (ai-readiness, llms-txt-validate, robots-txt-validate, schema-inspect, og-inspect, cloak, batch), the leaderboard APIs (live, rank, history, movers), llms.txt generator, badge SVG, public stats, sitewatch, and health. See the API Documentation for the exact list.
If you hit your plan's rate limit, the API will return a
429 Too Many Requests response. You can upgrade to a higher plan at any time. If you have temporary spikes, contact us and we can discuss a custom arrangement.
Honest answer: for a single quick check, the free tools are fine — run AI Readiness and Website Grade and you will see the same numbers the audit uses. The audit exists for three specific cases where the free flow breaks down: (1) you want a single combined report instead of flipping between tabs, (2) you want a print-ready page you can save as PDF and ship to a developer, client, or boss, and (3) you want the result to stay reachable at the same URL later. If none of those matter to you, stick with the free tools — we will not be upset.
Email hello@zerokit.dev within 30 days of the purchase with the Stripe receipt and we will refund you in full. No form, no questions. This is a one-time product, not a subscription — we would rather issue a refund than leave you stuck with a report you do not use.
Click any Get Started button above and check out with Stripe. Payment is instant. API keys (Starter / Pro) appear on the success page right after payment. Audit reports (\) render in the browser on the success page. No email wait. For Enterprise plans, contact hello@zerokit.dev.
