What it does

Apollo Install Auth is an agent skill from jeremylongshore/tons-of-skills-marketplace. Install and configure Apollo.io API authentication. Use when setting up a new Apollo integration, configuring API keys, or initializing Apollo client in your project. Trigger with phrases like "install apollo", "setup apollo api", "apollo authentication", "configure apollo api key".

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code

It sits in Backend & APIs, covering GraphQL. It works with Apollo GraphQL and Python. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Setting up a new Apollo integration
  • Configuring API keys
  • Initializing Apollo client in your project
  • With phrases like install apollo

Example prompts

  • “install apollo”
  • “setup apollo api”
  • “apollo authentication”
  • “/apollo-install-auth”

Requirements

  • Python 3
  • Node.js
  • A credential in APOLLO_API_KEY
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(npm:*), Bash(pip:*), Grep

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Install HTTP Client
  2. Configure API Key
  3. Create Apollo Client (TypeScript)
  4. Verify Connection
  5. Create Apollo Client (Python)

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash(npm:*)
    • Bash(pip:*)
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • pip
    • curl
    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.apollo.io

    Also links to:

    • docs.apollo.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • APOLLO_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Apollo Install Auth loads about 1.4k tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 236 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~76
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:59
    # Create .env file (never commit this)
  • NoteMentions a .env fileSKILL.md:60
    ho 'APOLLO_API_KEY=your-api-key-here' >> .env
  • NoteMentions a .env fileSKILL.md:61
    echo '.env' >> .gitignore

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Apollo Install & Auth

Overview

Set up Apollo.io API client and configure authentication credentials. Apollo uses the x-api-key HTTP header for authentication against the base URL https://api.apollo.io/api/v1/. There is no official SDK — all integrations use the REST API directly.

Prerequisites

  • Node.js 18+ or Python 3.10+
  • Package manager (npm, pnpm, or pip)
  • Apollo.io account with API access (Basic plan or above)
  • API key from Apollo dashboard (Settings > Integrations > API Keys)

Instructions

Step 1: Install HTTP Client
bash
set -euo pipefail
# Node.js
npm install axios dotenv

# Python
pip install requests python-dotenv
Step 2: Configure API Key

Apollo supports two API key types:

  • Master API key — full access to all endpoints (required for contacts, sequences, deals)
  • Standard API key — limited to search and enrichment only
bash
# Create .env file (never commit this)
echo 'APOLLO_API_KEY=your-api-key-here' >> .env
echo '.env' >> .gitignore
Step 3: Create Apollo Client (TypeScript)
typescript
// src/apollo/client.ts
import axios, { AxiosInstance } from 'axios';
import dotenv from 'dotenv';

dotenv.config();

const BASE_URL = 'https://api.apollo.io/api/v1';

export function createApolloClient(apiKey?: string): AxiosInstance {
  const key = apiKey ?? process.env.APOLLO_API_KEY;
  if (!key) throw new Error('APOLLO_API_KEY is not set');

  return axios.create({
    baseURL: BASE_URL,
    headers: {
      'Content-Type': 'application/json',
      'Cache-Control': 'no-cache',
      'x-api-key': key,
    },
    timeout: 30_000,
  });
}

export const apolloClient = createApolloClient();
Step 4: Verify Connection
typescript
// src/scripts/verify-auth.ts
import { apolloClient } from '../apollo/client';

async function verifyConnection() {
  try {
    // Use the health endpoint to test connectivity
    const response = await apolloClient.get('/auth/health');
    console.log('Apollo connection:', response.data.is_logged_in ? 'OK' : 'Invalid key');
  } catch (error: any) {
    if (error.response?.status === 401) {
      console.error('Invalid API key. Generate a new one at:');
      console.error('  Apollo Dashboard > Settings > Integrations > API Keys');
    } else {
      console.error('Connection failed:', error.message);
    }
  }
}

verifyConnection();
Step 5: Create Apollo Client (Python)
python
# apollo_client.py
import os
import requests
from dotenv import load_dotenv

load_dotenv()

class ApolloClient:
    BASE_URL = 'https://api.apollo.io/api/v1'

    def __init__(self, api_key: str | None = None):
        self.api_key = api_key or os.environ.get('APOLLO_API_KEY')
        if not self.api_key:
            raise ValueError('APOLLO_API_KEY is not set')
        self.session = requests.Session()
        self.session.headers.update({
            'Content-Type': 'application/json',
            'Cache-Control': 'no-cache',
            'x-api-key': self.api_key,
        })

    def get(self, endpoint: str, **kwargs) -> requests.Response:
        return self.session.get(f'{self.BASE_URL}/{endpoint}', **kwargs)

    def post(self, endpoint: str, json: dict = None, **kwargs) -> requests.Response:
        return self.session.post(f'{self.BASE_URL}/{endpoint}', json=json, **kwargs)

    def verify(self) -> bool:
        resp = self.get('auth/health')
        return resp.json().get('is_logged_in', False)

client = ApolloClient()
print('Connected:', client.verify())

Output

  • HTTP client configured with x-api-key header authentication
  • Environment variable file with .gitignore protection
  • Successful /auth/health verification
  • Both TypeScript and Python implementations

Error Handling

ErrorCauseSolution
401 UnauthorizedInvalid or missing API keyVerify key in Apollo Dashboard > Settings > Integrations > API Keys
403 ForbiddenEndpoint requires master keyGenerate a master API key (not standard) in the dashboard
429 Rate LimitedToo many requests per minuteImplement backoff; see apollo-rate-limits
Network ErrorFirewall blocking outbound HTTPSAllow outbound to api.apollo.io on port 443

Examples

Quick cURL Verification
bash
# Test your API key from the command line
curl -s -X GET \
  -H "Content-Type: application/json" \
  -H "Cache-Control: no-cache" \
  -H "x-api-key: $APOLLO_API_KEY" \
  "https://api.apollo.io/api/v1/auth/health" | python3 -m json.tool
