Analytics per account

Everything is asked per profile and, optionally, for one account. Dates go as YYYY-MM-DD; the default is the last 30 days.

Followers

curl

curl "https://api.usecrier.com/v1/analytics/followers?profileId=prf_8f2k4d&from=2026-10-01" \
  -H "Authorization: Bearer $CRIER_API_KEY"

Node

const res = await fetch('https://api.usecrier.com/v1/analytics/followers?profileId=prf_8f2k4d&from=2026-10-01', {
  headers: {
    Authorization: `Bearer ${process.env.CRIER_API_KEY}`,
  },
});
const { data } = await res.json();

Python

import os, requests

res = requests.get(
    "https://api.usecrier.com/v1/analytics/followers?profileId=prf_8f2k4d&from=2026-10-01",
    headers={"Authorization": f"Bearer {os.environ['CRIER_API_KEY']}"},
)
data = res.json()["data"]

Current followers, growth over the period and the daily history of each account. Networks refresh them once a day.
