ScraperCity + EmailBison

Query the Lead Database endpoint with your ICP filters. The example below pulls VP of Sales contacts in the computer software industry who have a verified email. You can swap in any combination of title, industry, location, company size, and more.

curl -s "https://app.scrapercity.com/api/v1/database/leads?title=VP+of+Sales&industry=computer%20software&hasEmail=true&limit=100" \
  -H "Authorization: Bearer $SCRAPERCITY_API_KEY"

The Lead Database returns up to 100 leads per page. Use the page parameter to paginate. The daily limit is 100,000 leads. Requires the $649/mo plan.

For each contact from the ScraperCity response, POST to the EmailBison leads endpoint. Include all fields you want available for personalization inside custom_variables.

curl -X POST "https://dedi.emailbison.com/api/leads" \
  -H "Authorization: Bearer $EMAILBISON_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "email": "[email protected]",
    "first_name": "Jane",
    "last_name": "Chen",
    "company": "SaaSCorp",
    "custom_variables": {
      "title": "VP of Sales",
      "linkedin": "https://linkedin.com/in/janechen",
      "industry": "Computer Software",
      "city": "San Francisco",
      "employee_count": "250"
    }
  }'

This creates the lead in your EmailBison workspace. Note the lead ID in the response for the next step. If the email already exists, EmailBison will return the existing lead record.

Add the leads to your target campaign by passing an array of lead IDs. You can collect IDs from step 2 and batch them together:

curl -X POST "https://dedi.emailbison.com/api/campaigns/6/leads" \
  -H "Authorization: Bearer $EMAILBISON_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "lead_ids": [101, 102, 103, 104, 105]
  }'

Leads added to an active campaign sync within 5 minutes and begin receiving sequence steps according to your campaign schedule.

For ongoing prospecting, wrap the three curl calls in a script that runs on a schedule. Here is the full flow in Node.js:

// import-leads.mjs
const SCRAPERCITY_KEY = process.env.SCRAPERCITY_API_KEY;
const BISON_TOKEN = process.env.EMAILBISON_TOKEN;
const BISON_BASE = 'https://dedi.emailbison.com/api';
const CAMPAIGN_ID = 6;

async function sleep(ms) {
  return new Promise((r) => setTimeout(r, ms));
}

async function bisonPost(path, body, attempt = 0) {
  const res = await fetch(`${BISON_BASE}${path}`, {
    method: 'POST',
    headers: {
      Authorization: `Bearer ${BISON_TOKEN}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify(body),
  });
  if (res.status === 429 && attempt < 5) {
    // Respect rate limits - back off and retry
    await sleep(Math.min(500 * 2 ** attempt, 30000));
    return bisonPost(path, body, attempt + 1);
  }
  return res.json();
}

async function run() {
  // 1. Pull leads from ScraperCity
  const sc = await fetch(
    'https://app.scrapercity.com/api/v1/database/leads?title=VP+of+Sales&industry=computer%20software&hasEmail=true&limit=100',
    { headers: { Authorization: `Bearer ${SCRAPERCITY_KEY}` } }
  );
  const { leads } = await sc.json();

  // 2. Create each lead in EmailBison
  const leadIds = [];
  for (const lead of leads) {
    const result = await bisonPost('/leads', {
      email: lead.email,
      first_name: lead.first_name,
      last_name: lead.last_name,
      company: lead.company,
      custom_variables: {
        title: lead.title,
        linkedin: lead.linkedin_url,
        industry: lead.industry,
        city: lead.city,
      },
    });
    if (result.id) leadIds.push(result.id);
    await sleep(200); // stay under rate limits
  }

  // 3. Attach to campaign
  await bisonPost(`/campaigns/${CAMPAIGN_ID}/leads`, { lead_ids: leadIds });
  console.log(`Imported ${leadIds.length} leads into campaign ${CAMPAIGN_ID}`);
}

run().catch(console.error);

Run with node import-leads.mjs or schedule via cron. The 200ms delay between lead creation calls keeps you well within EmailBison rate limits.
