SkillBoss API Hub - AI Cold Email Generator
Generate personalized cold email sequences from lead data. SkillBoss API Hub uses AI to research prospects and craft unique, relevant outreach - not templates.
Setup
- Get your API key at https://app.skillboss.co/settings (Integrations → API Keys)
- Set
SKILLBOSS_API_KEY in your environment
How It Works
This skill calls the SkillBoss API Hub (POST https://api.skillboss.co/v1/pilot) with type: "chat" to generate personalized cold email sequences for each lead. The AI automatically researches the lead's context and crafts relevant outreach based on company, title, and LinkedIn/website data.
Endpoints
All requests go to the SkillBoss API Hub unified endpoint:
POST https://api.skillboss.co/v1/pilot
Authorization: Bearer {SKILLBOSS_API_KEY}
Content-Type: application/json
Single Lead — Generate Email Sequence
Generate a cold email sequence for one lead (3–5 emails per lead). The request uses type: "chat" with a structured prompt containing lead data and sequence options.
{
"type": "chat",
"inputs": {
"messages": [
{
"role": "system",
"content": "You are an expert cold email copywriter. Generate personalized cold email sequences based on lead data. Each email should be unique, relevant, and high-converting. Return a JSON object with a 'sequence' array."
},
{
"role": "user",
"content": "Generate a cold email sequence for this lead:\n\nName: {lead.name}\nTitle: {lead.title}\nCompany: {lead.company}\nEmail: {lead.email}\nCompany Website: {lead.company_website}\nLinkedIn: {lead.linkedin_url}\n\nOptions:\n- Number of emails: {options.email_count}\n- Signature: {options.email_signature}\n- Campaign angle: {options.campaign_angle}\n- CTAs to use: {options.approved_ctas}\n\nReturn JSON: {\"sequence\": [{\"step\": 1, \"subject\": \"...\", \"body\": \"...\"}, ...]}"
}
]
},
"prefer": "quality"
}
Response (200):
{
"status": "success",
"result": {
"choices": [
{
"message": {
"content": "{\"sequence\": [{\"step\": 1, \"subject\": \"...\", \"body\": \"...\"}, {\"step\": 2, \"subject\": \"...\", \"body\": \"...\"}, {\"step\": 3, \"subject\": \"...\", \"body\": \"...\"}]}"
}
}
]
}
}
Parsing the result:
import json
raw = response.json()["result"]["choices"][0]["message"]["content"]
sequence = json.loads(raw)["sequence"]
Batch — Generate for Multiple Leads
For multiple leads, call the endpoint once per lead or construct a batch prompt:
{
"type": "chat",
"inputs": {
"messages": [
{
"role": "system",
"content": "You are an expert cold email copywriter. Generate personalized cold email sequences for each lead. Return a JSON object with a 'leads' array."
},
{
"role": "user",
"content": "Generate cold email sequences for these leads:\n\n{leads_json}\n\nOptions: email_count={options.email_count}, list_name={options.list_name}\n\nReturn JSON: {\"leads\": [{\"email\": \"...\", \"sequence\": [{\"step\": 1, \"subject\": \"...\", \"body\": \"...\"}]}]}"
}
]
},
"prefer": "quality"
}
Response parsing:
raw = response.json()["result"]["choices"][0]["message"]["content"]
result = json.loads(raw)
leads_with_sequences = result["leads"]
