Example use cases
SEO meta tag for blog post
“Write a meta description for this blog post content, max 160 characters, so I can add it to my site's HTML head tag: 'In this guide we walk through setting up a home vegetable garden from scratch, covering soil prep, seed selection, watering schedules, and common pest control tips.'”
Product page snippet for e-commerce
“Create a short meta description (under 200 characters) for this product page copy: 'The UltraFit Pro Yoga Mat is 6mm thick, made from eco-friendly TPE, with alignment lines and a non-slip surface — perfect for yoga, pilates, and stretching.'”
Auto-generate descriptions for CMS content

Endpoint
POSThttps://api.fastapi.online/meta-descriptionWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.001 USDC), no-signup-required meta description generation with configurable length, especially in automated pipelines where you want crypto micropayment billing per call rather than a subscription. It is well-suited for bulk CMS workflows, agent-driven SEO enrichment, or developer tooling where you need a lightweight summarization step without integrating a full LLM API.
