Just One API / Follower Growth History

Just One API tool justoneapi-api-xiaohongshu-pgy-api-solar-kol-data-userid-fans-overall-new-history on looot: input fields, $0.0223 per call, output shape, and code to run it with curl, JavaScript or Python.

Retrieve Xiaohongshu Pugongying follower history for a creator over the selected 30- or 90-day period. Use it to track total followers or new-follower growth over time.

Tool id: justoneapi-api-xiaohongshu-pgy-api-solar-kol-data-userid-fans-overall-new-history
Provider: Just One API
Job: Track a creator’s follower growth (creators.audience.growth)
Price: $0.0223 per call. A call that fails at the provider costs $0.

Inputs

Name	Type	Required	Description
`dateType`	string	no	Date range type
`increaseType`	string	no	Increase type
`userId`	string	yes

Output

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

{ code, data: { list: { num, dateKey }[], fansNumInc, fansNumIncRate }, message, requestId, recordTime }

Run it

Every call needs your API token in LOOOT_TOKEN; Sign in 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:

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-data-userid-fans-overall-new-history","input":{"userId":"<userId>"},"wait":30}'

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-data-userid-fans-overall-new-history",
    input: {
      userId: "<userId>",
    },
    wait: 30,
  }),
});
const run = await response.json();
console.log(run.status, run.result);
