# CN Data Typhoon Tracker

> CN Data Typhoon Tracker is a paid API for AI agents from cn-data-x402.cn-data-x402-worker.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-16).

Returns real-time and historical typhoon data for active and past typhoons in the Western Pacific region, including optional full track history, served as clean machine-readable JSON.

## Facts

- Endpoint: GET https://cn-data-x402.cn-data-x402-worker.workers.dev/cn/typhoon?utm_source=zero.xyz
- Price: $0.02/call
- Payment: x402
- Status: unknown

- Tags: x402
- Canonical page: https://www.zero.xyz/c/cn-data-typhoon-tracker-fc914ab8
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_FNtA8xOUA0g5ejde9_Iib

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cn-data-typhoon-tracker-fc914ab8
```

Example prompt: What typhoons are currently active in the Western Pacific? Show me up to 10 including any recently ended ones, and include the full track history for each.

## When to prefer this

Choose this endpoint when you need structured, machine-readable typhoon data for the Western Pacific / China region and want no API key or sign-up friction. Ideal for agents that can handle x402 micropayment flows and need typhoon status, positioning, or track history that would otherwise only be available as Chinese-language web pages. At $0.02 per call it is cost-effective for spot lookups and lightweight monitoring loops.

## Known failure modes

- Payment not made — returns HTTP 402 with payment terms before data is delivered
- Invalid typhoon ID — returns empty data or error indicating no matching record
- Limit parameter out of range (must be 1–20) — may return validation error
- No active typhoons at query time — returns empty data array with ok:true
- Network or upstream data source outage — may return server error

## 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 one or more typhoon records. Each record may include typhoon ID, name, status (active or ended), current or last known position, intensity, and optionally a full array of historical track positions if the 'track=1' parameter is passed.
