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 `ok: true` and a `data` block containing: location metadata (name, latitude, longitude, timezone), number of forecast days, and an array of daily forecasts each with date, weekday (in Chinese), weather description (in Chinese), weather code, max/min temperature in Celsius, precipitation in mm, precipitation probability percentage, max wind speed in km/h, and sunrise/sunset timestamps.
Example use cases
Event planning in Chinese city
“I'm organizing an outdoor event in Chengdu on October 10th — can you pull the 7-day weather forecast starting today so I can check if it's likely to rain?”
Logistics routing around weather
“We're shipping goods overland through Wuhan next week. Can you get me the 10-day weather forecast for Wuhan (lat 30.59, lon 114.3) so we can plan around storms or heavy rain?”
Travel packing for China trip
“I'm flying to Guangzhou in 3 days. Can you get me the 5-day forecast there — daily temperature ranges and precipitation — so I know what clothes to bring?”
Technical details
Endpoint
GEThttps://cn-data-x402.cn-data-x402-worker.workers.dev/cn/weather-forecast?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, machine-readable weather forecast data specifically for Chinese cities, especially when other international weather APIs do not support Chinese city names or Chinese-language descriptions. It requires no API key or signup — just a $0.02 USDC micropayment via the x402 protocol. Prefer it over scraping Chinese weather sites, which return unstructured HTML.
Side effects
- HTTP 402 returned if payment not yet made — must pay $0.02 USDC on Base and retry
- Unknown city name returns an error if not among the 14 preset Chinese cities
- Missing both city and lat/lon parameters results in a bad request error
- Days parameter outside 1-16 range may return a validation error or default to 7
- Network timeout on the Cloudflare Worker edge node
