Node.js

Using the CallPrep API with Node.js.

Installation

No SDK required — use the native fetch API (Node.js 18+) or any HTTP client.

# Optional — for older Node.js versions
npm install node-fetch

Minimal example

const API_KEY = process.env.CALLPREP_API_KEY;
const BASE    = 'https://rpiqzfzokrwxavztrpmp.supabase.co/functions/v1';

async function research(email) {
  // 1. Submit
  const res  = await fetch(`${BASE}/research`, {
    method:  'POST',
    headers: { 'Authorization': `Bearer ${API_KEY}`, 'Content-Type': 'application/json' },
    body:    JSON.stringify({ email }),
  });
  const { research_id } = await res.json();

  // 2. Poll
  while (true) {
    await new Promise(r => setTimeout(r, 5000));
    const s    = await fetch(`${BASE}/research-status/${research_id}`, {
      headers: { 'Authorization': `Bearer ${API_KEY}` },
    });
    const data = await s.json();
    if (data.status === 'completed') return data;
    if (data.status === 'failed')    throw new Error(data.error);
  }
}

const result = await research('[e-mail]');
console.log(result.data.prospect.opening_talk);

With TypeScript

interface ResearchResult {
  research_id:  string;
  status:       'completed' | 'failed' | 'processing' | 'queued';
  completed_at: string | null;
  data?: {
    prospect: {
      name:         string;
      title:        string;
      company:      string;
      summary:      string;
      opening_talk: string[];
    };
    company: {
      name:               string;
      synergy_points:     string[];
      discovery_questions:string[];
    };
    decision_makers: Array<{
      full_name:       string;
      position_title:  string;
      linkedin_url:    string;
    }>;
  };
}

async function research(email: string): Promise<ResearchResult> {
  const BASE    = 'https://rpiqzfzokrwxavztrpmp.supabase.co/functions/v1';
  const headers = {
    'Authorization': `Bearer ${process.env.CALLPREP_API_KEY}`,
    'Content-Type':  'application/json',
  };

  const init = await fetch(`${BASE}/research`, {
    method: 'POST', headers, body: JSON.stringify({ email }),
  });
  const { research_id } = await init.json();

  while (true) {
    await new Promise(r => setTimeout(r, 5000));
    const res  = await fetch(`${BASE}/research-status/${research_id}`, { headers });
    const data = await res.json() as ResearchResult;
    if (data.status === 'completed') return data;
    if (data.status === 'failed')    throw new Error(data.error as string);
  }
}

With Express.js

import express from 'express';

const app = express();
app.use(express.json());

app.post('/enrich', async (req, res) => {
  const { email } = req.body;
  if (!email) return res.status(400).json({ error: 'email required' });

  try {
    const data = await research(email);
    res.json(data);
  } catch (err) {
    res.status(500).json({ error: err.message });
  }
});

app.listen(3000);
