## How to call it through Zero

```sh
zero fetch --capability stockwaves-china-pulse-polling-api-1f6f5ed6
```

Example prompt: Poll the China social pulse right now and show me what topics have reached cross-platform consensus across Weibo, Baidu, and Douyin in the last 15 minutes, including any new finance-related trends — give me up to 10 results per section.

## When to prefer this

Choose this endpoint when you need to continuously monitor Chinese social media trends with low latency and low cost per poll. It is specifically designed for agent polling loops where detecting freshness (new_since) matters more than deep article content. Prefer this over full-text news APIs when you want structured, cross-platform consensus signals from Weibo, Baidu, and Douyin at $0.003 per call. Ideal for finance agents watching for China-originated market catalysts or social sentiment shifts in near real-time.

## Known failure modes

- Invalid 'since' value outside 1-120 range returns a 400 error
- Invalid 'limit' value outside 1-30 range returns a 400 error
- Payment failure (x402 micropayment not processed) blocks the request
- During low-activity periods the 'new_since' array may be empty if no new topics appeared
- Stale data possible if upstream platform APIs are temporarily delayed
- Rate limiting if polling too aggressively beyond the intended cadence

## How this service works

China pulse, cheap enough to POLL: what China is talking about RIGHT NOW and what is NEW since your last call - built for agents that monitor continuously. Returns `consensus` (phrases trending on 2+ of Weibo/Baidu/Douyin at once = nationwide attention, not single-board noise), a `finance` slice, and `new_since` (what entered the boards in the last N minutes) so every poll returns fresh information. Structure only, no article text. ?since=1-120&limit=1-30.

## Output

A structured JSON response containing: a 'consensus' array of phrases trending simultaneously on 2 or more of Weibo, Baidu, and Douyin (indicating genuine nationwide attention), a 'finance' slice of finance-specific trending topics, and a 'new_since' array of topics that first entered the hot boards within the requested lookback window. No article text — structured metadata only.
