Prerequisites

  • AI Pass account
  • 5 minutes

Step 1: Get API Credentials

  2. Go to Developer Dashboard → OAuth2 Clients
  3. Create client and copy Client ID

Step 2: Initialize SDK

<script src="https://aipass.one/aipass-sdk.js"></script>

const aipass = new AIPass({
  clientId: 'YOUR_CLIENT_ID',
  requireLogin: true
});

Step 3: Generate Resume

async function generateResume(profile, jobDescription = '') {
  const r = await aipass.apikey.v1.chat.completions({
    model: 'openai/gpt-4.1-mini',
    messages: [
      {
        role: 'system',
        content: `You are an expert resume writer. Create a professional, ATS-optimized resume. Include:
1. Professional summary (2-3 sentences)
2. Work experience with action verbs and metrics
3. Skills section (technical and soft skills)
4. Education

      },
      {
        role: 'user',
        content: `Create a resume for:\n${JSON.stringify(profile, null, 2)}`
      }
    ],
    temperature: 1,
    max_tokens: 16000
  });

  return r.choices[0].message.content;
}
