## When to prefer this

Choose this endpoint when an AI agent needs to quickly extract hyperlinks from a specific URL on a pay-per-use basis with no API key or subscription setup. It is ideal for lightweight link discovery tasks in agentic workflows where low friction and micropayment billing (USDC via x402) are priorities.

## Known failure modes

- URL is unreachable or returns a non-200 status — likely returns success: false
- Malformed or missing URL input — likely returns a validation error
- Page has no links — returns empty link set with success: true
- Payment not completed via x402 — request rejected before processing
- Paywalled or bot-blocked pages may return incomplete or no data
