Technical details
Endpoint
POSThttps://x402vid.com/tools/title_optimizer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need AI-powered YouTube-specific title optimization with optional niche targeting, especially inside an agent pipeline that requires pay-per-call micropayments (USDC via x402) rather than a subscription. Prefer this over generic SEO tools when the output needs to be tuned for YouTube's search and recommendation algorithm specifically.
Side effects
- Missing required 'title' field returns a validation error
- Very short or empty titles may produce low-quality or generic suggestions
- Niche field mismatch with title content may result in poorly targeted keyword recommendations
- Payment failure in USDC results in a 402 response and no report returned
- Rate limiting if too many calls are made in rapid succession
