How this service works
Chinese market and China-focused public data over the x402 protocol. No API key and no signup: call any endpoint, receive HTTP 402 with payment terms, pay the listed amount in USDC on Base and retry. Every response is JSON. Some Chinese-language sources are published only as web pages — these endpoints return them as clean, machine-readable JSON.
Output
A JSON object with an 'ok' status flag, a 'data' object containing an 'updatedAt' RFC-2822 timestamp and a 'foreignToCny' map of currency codes (e.g. EUR, HKD, JPY, USD) to their CNY exchange rates as decimal numbers, and the endpoint path.
Example use cases
RMB cross-border payment conversion
“I need to pay a supplier in China — what's the current USD to CNY exchange rate so I can calculate how much RMB they'll receive for a $50,000 wire?”
Multi-currency portfolio valuation in CNY
“I hold EUR, HKD, and JPY positions — can you pull the latest CNY rates for all three so I can calculate the total RMB value of my portfolio?”
Daily FX rate monitoring for reporting
“Fetch today's official Chinese yuan rates against major currencies so I can populate my daily FX rate report with the most current CNY figures.”
Technical details
Endpoint
GEThttps://cn-data-x402.cn-data-x402-worker.workers.dev/cn/fx?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need CNY exchange rates sourced specifically from Chinese market/official data, returned as clean structured JSON without requiring API key registration. Ideal for agents needing RMB conversion rates on demand with micro-payment access rather than a subscription. Prefer over generic FX APIs when the user explicitly needs China-side official rates rather than interbank mid-market rates from Western providers.
Side effects
- HTTP 402 returned before payment is made — must pay listed USDC amount on Base and retry
- Stale rates if the upstream Chinese data source has not refreshed — check updatedAt timestamp
- Currency codes not in the foreignToCny map if the source does not publish them
- Network or worker errors returning non-JSON responses
