## When to prefer this

Choose this endpoint when you need a quick, low-cost per-URL SEO audit without setting up a full SEO platform. Ideal for agents automating content workflows, pre-publish checks, or competitive research where you need on-demand SEO analysis via a simple HTTP call. At $0.0003 per call it is cost-effective for bulk page auditing in automated pipelines.

## Known failure modes

- Invalid or malformed URL returns an error
- URL is unreachable or returns a non-200 HTTP status, audit may fail or return partial results
- Paywalled or JavaScript-heavy pages may yield incomplete analysis
- Payment of 0.0003 USDC required per call; insufficient funds returns a 402 error
- Rate limiting may occur for high-volume usage
