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 object containing live readings across all major China market data categories: CNY onshore FX rate, CNH offshore FX rate, CNY-CNH spread, main contract prices for Chinese commodity futures, levels for China equity indices (e.g. CSI 300, Shanghai Composite), and the Baidu real-time hot-search attention score, all aggregated in a single response.
Example use cases
Pre-market China briefing for trader
“Before Asian markets open, pull me a complete China snapshot — onshore CNY, offshore CNH, their spread, major equity indices, commodity futures, and the Baidu sentiment signal — so I can see where things stand.”
Macro research cross-asset check
“I'm writing a China macro note. Can you grab me a cross-asset snapshot with the current RMB FX rates, equity index levels, commodity futures, and the Baidu hot-search signal all at once?”
Automated China market monitor
“Every hour, fetch the China market snapshot and alert me if the CNY-CNH spread widens beyond a certain threshold or if any equity index moves more than 1% from the previous reading.”
Technical details
Endpoint
GEThttps://china-market-data-api.vercel.app/v1/china/snapshot?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a broad, cross-asset view of Chinese financial markets in a single API call rather than fetching individual asset classes separately. Ideal for agents that need a holistic China market pulse — FX, equities, commodities, and sentiment together — without managing multiple endpoints or API keys. The pay-per-call USDC model (no signup required) makes it suitable for low-frequency or one-off queries.
Side effects
- HTTP 402 returned if USDC payment via x402 is missing or invalid
- Data feed outage during Chinese market closure hours may return stale or unavailable values
- Network timeout if upstream market data providers are slow
- Malformed response if snapshot aggregation partially fails across asset classes
