Using Make, n8n or Zapier? Here is every field for the HTTP request

Use the HTTP request module or node your tool offers. You need three steps: send the list, wait, then read the results.

1. Send your list (HTTP request)

Method
POST
URL
https://api.datablist.com/v1/enrichments/tasks

Body (JSON)

{
"enrichmentId": "waterfall-personal-email-finder",

{"inputId": "row-3", "data": {"profileUrl": "https://www.linkedin.com/in/lea-moreau/"}}
]
}
Keep
The @id from the response. That is your task ID.

2. Wait until it is done

Add a short wait or delay, then a GET request to https://api.datablist.com/v1/enrichments/tasks/TASK_ID with the same X-API-Key header. Repeat until status is completed.

3. Read the results

GET https://api.datablist.com/v1/enrichments/tasks/TASK_ID/results?limit=50. Map outputs to your columns. If nextCursor is not empty, call again with &cursor= plus that value.

Use Cases

What Teams Build With It

Put Waterfall Personal Email Finder wherever your data already flows.

Recruiting

Reach passive candidates

  1. Candidate LinkedIn URL
  2. Find the personal email
  3. Outreach from your ATS

Contact candidates on the address they read outside work, without going through their current employer.

Founders and B2C

Contact creators and freelancers

  1. Creator or freelancer profile
  2. Find the personal email
  3. Added to your campaign

Freelancers, consultants and creators often have no work email. Their personal email is the way in.

Alumni and Community

Keep in touch after job changes

  1. Alumni or customer list
  2. Find the personal email
  3. Contact that stays valid

Work emails bounce when people move on. A personal email keeps your community list reachable.

Pricing

How credits work

1,000 credits = $1, so each credit costs a tenth of a cent. A personal email found costs 75 credits. Profiles without a result are not charged, so the estimate above is the maximum. Every result returns creditsUsed, so you can track the real cost per row. Plan credits renew monthly and reset if unused. Top-up credits never expire.

For Developers

Build It Into Your Code

Everything you need to call the REST API directly: code, responses, endpoints, fields, authentication and limits.

Copy, Paste, Run

A complete script that creates a task, waits for it and prints every result. Replace YOUR_PERSONAL_API_KEY with your key.

# 1. Create the task (returns 202 Accepted and the task "@id")
curl --request POST 'https://api.datablist.com/v1/enrichments/tasks' \
--header 'X-API-Key: YOUR_PERSONAL_API_KEY' \
--header 'Content-Type: application/json' \
--data '{
"enrichmentId": "waterfall-personal-email-finder",
"uniqueId": "waterfall-personal-email-finder-import-1",
"settings": {},
"inputs": [
{"inputId": "row-1", "data": {"profileUrl": "https://www.linkedin.com/in/maya-lindqvist/"}},
{"inputId": "row-2", "data": {"profileUrl": "https://www.linkedin.com/in/tom-okafor/"}},
{"inputId": "row-3", "data": {"profileUrl": "https://www.linkedin.com/in/lea-moreau/"}}
]
}'
# 2. Poll every few seconds until status is completed, failed or stopped
curl 'https://api.datablist.com/v1/enrichments/tasks/TASK_ID' \
--header 'X-API-Key: YOUR_PERSONAL_API_KEY'
# 3. Read the results, then follow nextCursor until it is null
curl 'https://api.datablist.com/v1/enrichments/tasks/TASK_ID/results?limit=50' \
--header 'X-API-Key: YOUR_PERSONAL_API_KEY'
