## How to call it through Zero

```sh
zero fetch --capability cn-data-cny-fixing-rate-3fad7e71
```

Example prompt: What is the PBOC official CNY fixing rate today for USD, EUR, and JPY? Give me the latest 5 records for each.

## When to prefer this

Choose this endpoint when you need the official PBOC central parity (fixing) rate for CNY rather than market/spot rates. It is ideal for compliance, invoicing, or financial reporting that requires the authoritative government-published rate. No API key or signup required — just pay per call in USDC, making it suitable for lightweight or infrequent lookups without account overhead.

## Known failure modes

- HTTP 402 returned on first call — must pay 0.02 USDC on Base via x402 protocol before data is returned
- Invalid or unsupported currency code returns empty or error data
- Limit parameter out of range (must be 1–40) may result in an error or clamped response
- Data may not be available on Chinese public holidays when PBOC does not publish rates

## 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` boolean and a `data` field containing an array of CNY central parity fixing records, each including the currency code, date, and official exchange rate as published by the People's Bank of China.
