How this service works
China market data for AI agents, paid per call in USDC via x402 (HTTP 402). No signup, no API key. Endpoints cover RMB onshore and offshore FX with their spread, Chinese commodity futures main contracts, China equity indices, a Baidu real-time hot-search attention signal, and a one-call cross-asset snapshot. A free /v1/china/sample endpoint returns live samples of every dataset so a client can size the data before paying.
Output
A JSON response containing the current Baidu real-time hot-search list, including trending topic names, ranks, and associated attention scores or search volumes reflecting live Chinese internet interest.
Example use cases
China market sentiment for trading
“Pull the current Baidu hot-search rankings — I want to see if any financial or macro topics are spiking in Chinese public attention before the market opens.”
Brand monitoring in China
“Check what's trending on Baidu right now and tell me if our brand or any related topics appear in the hot-search list.”
Cross-asset China snapshot enrichment
“Get me the live Baidu hot-search signal so I can combine it with Chinese equity and FX data for my cross-asset China dashboard.”

GEThttps://china-market-data-api.vercel.app/v1/china/hotsearch?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
