Basanta SEO API — Documentation

Overview

The Basanta SEO API provides lightweight, fast access to SEO authority-style metrics for any domain or URL. It returns a clean JSON object with three fields: domain_rating, url_rating, and ahrefs_rank.

These metrics are provided for SEO research, comparison, and workflow automation. They should not be treated as direct Google ranking factors or guaranteed ranking predictions. Not affiliated with Ahrefs, Google, Moz, or Semrush.

Error Responses

Rate Limits

The API is completely free with no hard rate limits. We ask that you use it responsibly and avoid excessive automated requests. Responses are cached for performance.

Authentication

No authentication required. The API is open and free to use. Simply make HTTP requests to the endpoint.

# No API key needed - just make the request
curl "https://seo.basantasapkota.com/api/seo?url=example.com"

Best Practices

• 1.Pass clean domain names without protocol (e.g. example.com, not https://example.com) for consistent results.
• 2.Cache responses on your end to avoid redundant API calls and stay within rate limits.
• 3.Handle 429 errors gracefully — add retry logic with exponential backoff.
• 4.Do not use the API for real-time user-facing features without caching — it is optimized for background workflows.
• 5.Store your API key securely. Never expose it in client-side code or public repositories.
