What is OpenMerch Email Verify?
The OpenMerch Email Verify skill is a robust solution designed to evaluate the quality, deliverability, and reputation of individual email addresses. By integrating with OpenMerch services, this tool empowers developers and automated agents to identify disposable, free, or role-based addresses alongside an overall quality score. This ensures high-integrity customer databases and protects domain reputations from bounce-backs.
As part of the wider library of Openclaw Skills, this utility automates the multi-step verification process—planning, executing, and polling—while strictly managing consumption costs and preventing double charges through transactional idempotency.
OpenMerch Email Verify Use Cases
- Lead Cleansing: Automatically filter out invalid or disposable email addresses from signup forms in real time.
- Risk Mitigation: Block temporary or spam-oriented role addresses during customer registration cycles to reduce fraud.
- Cost Control: Check exact transaction costs and enforce spending limits before validating target emails.
- Agentic Workflows: Equip autonomous AI agents within the Openclaw Skills ecosystem to verify contact lists during pipeline automation.
How OpenMerch Email Verify Works
- Pre-execution Plan: Query the /v1/plan endpoint to verify if the job can run and fetch the guaranteed price in microcents.
- Secure Execution: Submit the validation request to /v1/execute utilizing a unique UUID v4 idempotency key to prevent accidental duplicate charges.
- Asynchronous Polling: If the response indicates an executing state, poll the /v1/jobs/{job_id} endpoint until completion.
- Result Processing: Extract and normalize key data indicators like deliverability status, quality score, and cost metrics.
OpenMerch Email Verify Setup
Configure your environment by obtaining an API key from your OpenMerch Developer Dashboard.
# Set your OpenMerch live API key
export OPENMERCH_API_KEY="om_live_xxxxxxxx"
# Optional: Customize the base URL for testing environments
export OPENMERCH_BASE_URL="https://api.openmerch.dev"
You can run the verification natively using Node.js (version 18+) or raw cURL queries:
# Method A: Execute via the reference script
node verify-email.mjs [email protected]
