What it does

The official CNY central parity rate (人民币汇率中间价) published daily by CFETS / China Foreign Exchange Trade System — the reference rate used for cross-border settlement, accounting and customs valuation in China. Every quoted currency comes with its Chinese and English pair name, today's fixing, the change in basis points versus the previous trading day and the implied previous fixing. Filter with ?currency=USD,EUR and ?limit=1-40. Different from /cn/fx, which returns live market spot rates. 中文:人民币汇率中间价(央行/CFETS 官方定盘价),含相对上一交易日的基点变动。 No API key and no signup: call the endpoint, it answers HTTP 402 with the payment terms, pay per request in USDC on Base with any x402-compatible client or wallet, then retry the same request to get the data.

Use with an agent

  1. Discover. Agents find this listing with GET https://bazaar.saylorinnovations.com/discovery/search?query=…, the MCP tool search_resources, or /discovery/resources.
  2. Inspect. Fetch /resources/74977.json for the price and payment options.
  3. Pay. Call GET https://cn-data-x402.cn-data-x402-worker.workers.dev/cn/cny-fixing. The provider answers 402 with its payment requirements. An x402 client signs one of the options below and retries with PAYMENT-SIGNATURE.
  4. Execute. The provider returns 200 with the data. Agent Bazaar is not in the request path and never sees your payment.

For humans

You don't need an account or an API key; you need a wallet holding a small amount of USDC on Base, and an x402-capable client (see the examples below). Call the endpoint unpaid first to see exactly what it asks for.
