```sh
zero fetch --capability china-market-data-api-baidu-hot-search-attention-signal-098ee4c1

## When to prefer this

Choose this endpoint when you need a real-time, no-signup, pay-per-call Baidu hot-search attention signal — especially useful for quantitative traders, China market analysts, or AI agents that need a live pulse on Chinese public interest without managing API keys or subscriptions. Prefer this over scraping or third-party aggregators when you want low-friction, programmatic access to Chinese search trend data paired with other China market signals from the same provider.

## Known failure modes

- Upstream Baidu data unavailable — API may return 503 or empty payload
- Payment not processed correctly via x402 — HTTP 402 returned requiring USDC payment
- Rate limiting or server-side error on the Vercel deployment
- Stale data if Baidu's feed has a delay — timestamps should be checked
- Malformed JSON response if the upstream feed structure changes
