ValidKit

Email validation infrastructure built for AI agents and high-scale automation.

🚀 Why ValidKit?

AI agents need reliable email validation at scale. ValidKit provides:

• 10,000 emails in 7-10 seconds - Built for agent-scale operations
• 80% smaller responses - Token-optimized for LLM efficiency
• 3,000 validations/second - No more rate limit frustrations
• Agent-first design - No dashboards, just APIs

📦 Quick Start

Node.js/TypeScript

npm install @validkit/sdk

import { ValidKit } from '@validkit/sdk';

const validkit = new ValidKit({ api_key: 'your-api-key' });
const result = await validkit.verifyEmail('user@example.com');

Python

pip install validkit

from validkit import ValidKit

async with ValidKit(api_key='your-api-key') as validkit:
    result = await validkit.verify_email('user@example.com')

Command Line

npm install -g @validkit/cli
validkit verify user@example.com

)

Token-Optimized Responses

// 80% smaller responses with compact format
const results = await validkit.verifyBatch(emails, {
  format: ResponseFormat.COMPACT
});
// Returns: [{e: "user@example.com", v: true}, ...]

Multi-Agent Tracing

// Track validation across agent workflows
const result = await validkit.verifyEmail(email, {
  trace_id: 'agent-123',
  parent_id: 'workflow-456'
});
