{/* Generated by scripts/generate-api-reference.mjs from data/api-reference.json. Do not edit. */}

Retrieve the Xiaohongshu Pugongying follower summary for a known creator. Use it to review the account's aggregate audience status before deeper demographic or trend analysis.

- **Tool id:** `justoneapi-api-xiaohongshu-pgy-api-solar-kol-datav3-fanssummary`
- **Provider:** [Just One API](/providers/justoneapi)
- **Job:** [Break down a creator's audience](/reference/jobs/creators-audience-profile) (`creators.audience.profile`)
- **Price:** $0.0223 per call. A call that fails at the provider costs $0.

## Inputs

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `userId` | string | yes |   |

## Output

Shape of the run's `result`, the expected shape, not yet checked against real answers:

```txt
{ code, data: { fansNum, readFansIn30, readFansRate, activeFansL28, engageFansL30, activeFansRate, engageFansRate, fansGrowthRate, fansIncreaseNum, payFansUserNum30d, payFansUserRate30d, readFansBeyondRate, activeFansBeyondRate, engageFansBeyondRate, fansGrowthBeyondRate }, message, requestId, recordTime }
```

## Run it

Every call needs your API token in `LOOOT_TOKEN`; [Sign in](/get-started/sign-in#use-the-token-in-scripts-and-agents) shows how to get one. Each run also needs a new idempotency key, so a retry never pays twice. With `wait: 30` the answer comes back inline when the run ends within 30 seconds. Otherwise you get the running run back: poll `GET /v1/runs/<runId>`.

Example input with placeholder values:

<CodeGroup>

```bash curl
curl -X POST "https://api.looot.ai/v1/runs" \
  -H "Authorization: Bearer $LOOOT_TOKEN" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{"endpointId":"justoneapi-api-xiaohongshu-pgy-api-solar-kol-datav3-fanssummary","input":{"userId":"<userId>"},"wait":30}'
```

```js JavaScript
const response = await fetch("https://api.looot.ai/v1/runs", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.LOOOT_TOKEN}`,
    "Content-Type": "application/json",
    "Idempotency-Key": crypto.randomUUID(),
  },
  body: JSON.stringify({
    endpointId: "justoneapi-api-xiaohongshu-pgy-api-solar-kol-datav3-fanssummary",
    input: {
      userId: "<userId>",
    },
    wait: 30,
  }),
});
const run = await response.json();
console.log(run.status, run.result);
```

```python Python
import os
import uuid

import requests

response = requests.post(
    "https://api.looot.ai/v1/runs",
    headers={
        "Authorization": f"Bearer {os.environ['LOOOT_TOKEN']}",
        "Idempotency-Key": str(uuid.uuid4()),
    },
    json={
        "endpointId": "justoneapi-api-xiaohongshu-pgy-api-solar-kol-datav3-fanssummary",
        "input": {
            "userId": "<userId>",
        },
        "wait": 30,
    },
    timeout=90,
)
run = response.json()
print(run["status"], run.get("result"))
```

To let looot pick among every provider of this job instead, send `job:creators.audience.profile` as `endpointId`; see [the job page](/reference/jobs/creators-audience-profile).
