For Agents
Verify whether email addresses are valid and deliverable, as single checks, small batches, or bulk list jobs, and track remaining credits.
Use for: Verify whether an email address is deliverable, Check a batch of email addresses at once, Upload a list of emails for bulk verification, Get the status of a bulk verification job
Not supported: Does not send email, find email addresses, or warm up inboxes. Use for verifying whether email addresses are valid and deliverable only.
The Easy Email Verification API checks whether email addresses are valid and deliverable, one at a time, in small batches, or as bulk lists. A single-address check returns a verdict in one call, a batch check handles several addresses in one request, and the bulk flow uploads a list, runs it as a job, and lets you download the results when it finishes. A credits endpoint reports the account's remaining allowance so a workflow can budget large runs.
Install Jentic One Beta
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Easy Email Verification API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.
Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Feasyemailverification.com%2Feasyemailverification" | shStep 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Feasyemailverification.com%2Feasyemailverification" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
What an agent can do with Easy Email Verification API.
Verify a single email address and get a deliverability verdict
Verify a small batch of email addresses in one request
Upload a list for bulk verification and run it as a job
List bulk jobs and check the status of one
Download the results of a completed bulk job
Check the account's remaining verification credits
Patterns agents use Easy Email Verification API for, with concrete tasks.
★ Agent-driven email verification
An AI agent connected through Jentic verifies an email address before a workflow trusts it, returning a deliverability verdict so a signup or lead is checked at the point of entry. The single-address check responds in one call, so the agent can gate an action on a real-time result.
Verify a single email address and report whether it is valid and deliverable
Bulk list cleaning
Marketing and data teams clean an email list by uploading it for bulk verification, polling the job status, and downloading the verified results. Easy Email Verification runs the list as a job and exposes status and download endpoints, so an agent can wait for completion before pulling the cleaned output.
Upload an email list for bulk verification, poll the job until complete, and download the results
Credit-aware verification
Before a large run, a workflow checks the account's remaining verification credits so it does not start a job it cannot finish. The credits endpoint reports the current allowance, letting an agent decide whether to verify now or wait for a top-up.
Check the remaining verification credits and only start a bulk job if there are enough for the list size
8 endpoints — the easy email verification api checks whether email addresses are valid and deliverable, one at a time, in small batches, or as bulk lists.

Setup
Wiring Easy Email Verification by hand means picking one of its key-passing styles, the X-API-Key header, an apikey query or header, or the Authorization header, and managing the upload-poll-download cycle for bulk jobs yourself. Through Jentic you install once, import it from the API Directory, store the key once, and your agent calls it.
Permission scoping
Easy Email Verification carries the bulk job id in the URL path on the status and download operations, so a rule can pin your agent to verification and result reads. You choose the operations it may call, so deleting a bulk job is not included unless you add it.
Credential isolation
Your Easy Email Verification key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'verify an email address' or 'verify an email list in bulk', and Jentic returns the matching operation with its input schema so the agent calls the right endpoint without browsing the reference docs.
Alternatives and complements available in the Jentic catalogue.
Specific to using Easy Email Verification API through Jentic.
What authentication does the Easy Email Verification API use?
The Easy Email Verification API accepts an API key in the X-API-Key header per its OpenAPI spec. It also accepts the key as an apikey query parameter, an apikey header, or in the Authorization header, so you can pass it whichever way fits the call. Through Jentic the key is stored once and injected at call time so it never enters the agent's prompt.
Can I verify a list of emails in bulk with the Easy Email Verification API?
Yes. You upload a list to the bulk endpoint, which runs it as a job, then poll the job status and download the results once it completes. Single-address and small-batch checks are also available for real-time use.
What are the rate limits for the Easy Email Verification API?
The OpenAPI spec does not publish fixed rate limits, but it does expose a credits endpoint so you can read the account's remaining allowance. Check the Easy Email Verification documentation for the limits that apply to your plan before large runs.
Is there an Easy Email Verification API MCP server?
You don't need an MCP server to give your agent the Easy Email Verification API. Jentic connects it directly from the API Directory: import it, store your key once, and your agent verifies addresses on demand without loading another server's tool definitions into its context.
Can I limit what my agent is allowed to do with the Easy Email Verification API?
Yes. Write a rule that allows only the verify and bulk-status operations, so the agent can check addresses and read job results but cannot delete a bulk job, and every call it makes is logged for review.
How do I verify an email with the Easy Email Verification API through Jentic?
Search Jentic for 'verify an email address', add the Easy Email Verification API from the directory, and store your key once; your agent can then check single addresses or bulk lists on demand. To run it on your own infrastructure, install Jentic One from its GitHub repo.
