When to prefer

Use this endpoint when you need to enrich a URL with human-readable preview metadata (title, description, OG image) for display, summarization, or content enrichment purposes — especially in agentic workflows that require pay-per-call micropayments via USDC on Base and need a lightweight, low-cost solution

Side effects

Private, loopback, or metadata IP addresses are rejected with an error
URL is unreachable or times out — no metadata returned
Page has no Open Graph tags — fields may be null or empty
Malformed or non-http(s) URL returns a validation error
Payment of 0.001 USDC via x402 on Base must succeed before content is returned
