Introduction
Zyptora provides a RESTful API that gives you programmatic access to all our free SEO tools. You can run on‑page audits, validate schema markup, test robots.txt rules, trace redirects, and much more.
Base URL: https://zyptora.com/api
All endpoints return JSON. Standard HTTP response codes are used. Successful requests return 200 OK; errors return 4xx or 5xx with a descriptive message.
Authentication
Currently, the public API is free and does not require an API key for basic usage. However, to avoid abuse, we enforce rate limits (see below). For higher limits, dedicated support, and SLA, consider our Agency or Enterprise plans.
curl "https://zyptora.com/api/seo-check?url=https://example.com"
Rate Limits
| Plan | Requests / Day | Concurrency |
|---|---|---|
| Free | 100 | 1 request at a time |
| Agency | 10,000 | 10 concurrent |
| Enterprise | Custom | Custom |
Exceeding limits returns 429 Too Many Requests. Contact us to raise your limits.
