You can enjoy our service's features with our simple JSON API. Three main calls are available:
Our API also provides you a RESTful way to manage your Hunter's resources. These are the resources you can Create, Read, Update and Delete with our API:
https://api.hunter.io/v2/
Our API is designed to be as simple to use as possible. We always use the same basic structure:
data
contains the data you requested.
meta
provides information regarding your
request.
errors
shows errors with insights regarding what
made the request fail. Learn more about the
errors responses.
{ "data": { ... }, "meta": { ... } }
{ "errors": { ... } }
Authentication is made with a key you will have to add to every call you make to our API. This parameter is always required. We'll return an error if the key is either missing or invalid.
It can be passed in the api_key
query parameter or in the X-API-KEY
header.
Your API key is what identifies your account, so make sure to keep it secret! You can at anytime generate or delete API keys on your dashboard.
A special API key can be used to test our API:
test-api-key
. It will validate the
provided parameters, but will always return the same, dummy, response.
It is available on our three main endpoints: the
Domain Search, the
Email Finder, and the
Email Verifier.

Hunter's API uses conventional HTTP response codes to indicate the success or failure of an API request. In case of error, the API returns an array of errors containing information regarding what happened.
200 - OK | The request was successful. |
201 - Created | The request was successful and the resource was created. |
204 - No content | The request was successful and no additional content was sent. |
400 - Bad request | Your request was not valid. It was missing a required parameter or a supplied parameter was invalid. |
401 - Unauthorized | No valid API key was provided. |
403 - Forbidden | You have reached the rate limit. |
404 - Not found | The requested resource does not exist. |
422 - Unprocessable entity | Your request is valid but the creation of the resource failed. Check the errors. |
429 - Too many requests | You have reached your usage limit. Upgrade your plan if necessary. |
5XX - Server errors | Something went wrong on Hunter's end. |
{ "errors": [ { "id": "wrong_params", "code": 400, "details": "You are missing the domain parameter" } ] }
One key feature of Hunter is to search all the email addresses corresponding to one website. You give one domain name and it returns all the email addresses using this domain name found on the internet.
domain
Required*
|
Domain name from which you want to find the email addresses. For example, "stripe.com". |
company
Required*
|
The company name from which you want to find the email addresses. For example, "stripe". Note that you'll get better results by supplying the domain name as we won't have to find it. If you send a request with both the domain and the company name, we'll use the domain name. It doesn't need to be in lowercase. |
limit | Specifies the max number of email addresses to return. The default is 10. |
offset | Specifies the number of email addresses to skip. The default is 0. |
type |
Get only personal or generic
email addresses.
|
seniority |
Get only email addresses for people with the selected seniority level.
The possible values are junior , senior
or executive . Several seniority levels can be
selected (delimited by a comma).
|
department |
Get only email addresses for people working in the selected
department(s). The possible values are executive ,
it , finance , management ,
sales , legal , support ,
hr , marketing , communication ,
education , design , health
or operations . Several departments can be selected (comma-delimited).
|
required_field |
Get only email addresses that have the selected field(s).
The possible values are full_name ,
position , phone_number .
Several fields can be selected (comma-delimited).
|
api_key
Required
|
Your secret API key. You can generate it in your dashboard. |
Each response will return up to 100 emails. Use the "offset" parameter to get all of them. A new query is counted for calls returning at least one result.
The number of sources is limited to 20 for each email address.
The
extracted_on
attribute of a source contains the date it was found for the first time, whereas the
last_seen_on
attribute contains the date it was found for the last time.
type
returns the value "personal" or "generic". A "generic" email address
is a role-based email address, like contact@hunter.io. On the
contrary, a "personal" email address is the address of someone in
the company.
confidence
is our estimation of the probability the email address returned is
correct. It depends on several criteria such as the number and
quality of sources.
The Domain Search API endpoint is rate limited to 15 requests per second and 500 requests per minute.
* You must send at least the domain name or the company name. You can also send both.
Here are the errors specific to the Domain Search API call. If you can't find an error in the list, please also check the general API errors.

This API endpoint allows you to verify the deliverability of an email address.
This endpoint imposes a daily rate limit based on the domain name. You can
check the number of requests remaining on the domain using the
X-Rate-Limit-Remaining

a response in time, we will return a 202
status code.
You will then be able to poll the same endpoint to get
the verification's result. Of course, all the requests in this case
are counted only once.

Add a recipient to a campaign. The parameters must be passed as a JSON hash.
As the recipient is added, we try to associate it with one of your leads with the same email, or create a new lead in your current list if there's no match. This enables you to send personalized emails by using attributes.
The response contains the
skipped_recipients
array with emails that were not added to the campaign with the corresponding reason.
The %code reason
can be one of:
duplicate
- email is already added to the campaign
invalid
- email has invalid format
removed
- email was already removed from the campaign
bounced
- previous email sent to this recipient bounced
unsubscribed
- recipient unsubscribed from your emails
claimed
- recipient decided not to receive any emails
Note that when adding a recipient to an active campaign, the email might be sent shortly after your API call, leaving you no time to cancel the sending in case of a mistake.
