**Category:** Social Media | **Website:** [www.zhihu.com/](https://www.zhihu.com/) | **Docs:** [parse.bot/marketplace/eb24f0ce-9914-4aac-8ce3-d506dfc0e782/zhihu-com-api](https://parse.bot/marketplace/eb24f0ce-9914-4aac-8ce3-d506dfc0e782/zhihu-com-api)

Pay-per-use API proxy for Locus Pro. Each call burns credits from your workspace balance.

## Access

**Base URL:** `https://api.beta.paywithlocus.com/api/wrapped/credits/zhihu-web/`
**Auth:** `Authorization: Bearer <LOCUS_CREDITS_SECRET_KEY>` (an `lcr_` secret key or a scoped `lcac_` agent credential)
**Required header:** `Idempotency-Key: <fresh UUID per call>`. A retry with the same key replays the stored result without a new charge.
**Response:** the provider response after any endpoint-specific normalization. `X-Locus-Credits-Charged` carries the charge and `X-Locus-Credits-Balance` the remaining balance. Insufficient credits return `402` before the provider is called.
**Pricing:** estimated costs below are USD. Locus debits the credit equivalent at your workspace rate.

> Using a Pay With Locus wallet key (`claw_` prefix)? Wallet routes are documented separately: https://docs.paywithlocus.com/wrapped-apis/for-agents

## Endpoints

### Get hot list

Retrieve the current Zhihu hot list (热榜) for a given category. Returns up to 50 ranked trending questions with metadata including heat score, answer count, follower count, and excerpt. Each category returns approximately 30 items. The list refreshes periodically throughout the day.

**Estimated cost:** Metered

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `category` | string | No | Hot list category to retrieve. Omitting returns the general/total hot list. |
| `limit` | integer | No | Maximum number of items to return. Clamped to 50. |

```bash
curl -X POST https://api.beta.paywithlocus.com/api/wrapped/credits/zhihu-web/get-hot-list \
  -H "Authorization: Bearer $LOCUS_CREDITS_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{"category":"<string>","limit":"<integer>"}'
```
