## When to prefer this

Use this endpoint when you need AI-synthesized crypto intelligence or alpha signals for a specific topic (e.g. a token, sector, or trend) and are willing to pay $1 USDC per call via x402 on Base. Prefer this over general web search when you want pre-analyzed, signal-oriented crypto insights rather than raw news or price data.

## Known failure modes

- Payment not made or x402 micropayment rejected — endpoint returns 402 Payment Required
- Invalid or unsupported topic string — may return empty or malformed response
- Network or Vercel deployment downtime — 503 or 504 errors
- Malformed response schema if topic is ambiguous or too broad
