Example prompt: Can you run a full technical SEO audit on https://www.example.com and tell me what issues are hurting its search rankings — things like crawl errors, missing meta tags, slow pages, and broken links?

## When to prefer this

Choose this endpoint when you need a comprehensive, automated technical SEO audit of a website covering crawl health, indexability, on-page signals, and performance. Prefer this over generic web scraping when the goal is specifically SEO diagnosis and actionable technical recommendations rather than raw content extraction.

## Known failure modes

- Invalid or unreachable URL provided — audit cannot crawl the target site
- Payment of 0.525 USDC not fulfilled — job not initiated
- Job times out if the target site is very large or slow to respond
- Domain blocked or disallowed by robots.txt — partial audit results
- Service returns job ID but results require polling the job status endpoint
