Migration Calculator API — Developer Documentation

Quick start

The fastest way to test the API is a GET request with query parameters. This example estimates an Office 365 tenant-to-tenant migration for 50 users with no file containers, complex permissions or Teams migration.

curl.exe "https://neodefender.com/api/migration-calculator/calculate?platform=office365&users=50&files_included=false"

Expected total: $4,250.

Endpoints

Method	URL	Use case	Cache
GET	https://neodefender.com/api/migration-calculator/calculate	Browser tests and simple HTTP clients.	public, max-age=60
POST	https://neodefender.com/api/migration-calculator/calculate	Applications sending JSON bodies.	no-store

Both variants return the same JSON response and use the same pricing function. CORS is public. No authentication is required.

Parameters

Name	Type	Required	Description
platform	string	Yes	office365, google-workspace, exchange, zimbra, imap, cpanel
users	integer	Yes	1-9999. More than 500 returns enterprise planning state.
files_included	boolean	Yes	true/false, or 1/0 for GET requests.
file_containers	integer	No	0-1000. Required when files_included=true.
complex_permissions	string	No	none, 1-5, 6-20, 20+. Defaults to none.
teams_included	boolean	No	true/false, or 1/0. Defaults to false.

Legacy platforms are exchange, zimbra, imap and cpanel. File migration is only valid for office365 and google-workspace.

Response

A successful response returns the calculated total, project tier, timeline and cost breakdown.

Examples

GET example

POST example

curl.exe -X POST "https://neodefender.com/api/migration-calculator/calculate" ^
  -H "Content-Type: application/json" ^
  -d "{\"platform\":\"office365\",\"users\":200,\"files_included\":true,\"file_containers\":12,\"complex_permissions\":\"6-20\",\"teams_included\":true}"

Enterprise state

curl.exe "https://neodefender.com/api/migration-calculator/calculate?platform=office365&users=750&files_included=false"

Rate limiting

The migration calculator API allows 10 requests per IP per minute. GET and POST share the same counter. When the limit is exceeded, the API returns429 with a Retry-After: 60 header.

Header	Description
X-RateLimit-Limit	Maximum requests allowed in the current window.
X-RateLimit-Remaining	Requests remaining in the current window.
Retry-After	Seconds to wait before retrying after a 429.

Errors

400 — Validation failed

Returned when parameters are missing, invalid, out of range, duplicated, or incompatible.

429 — Too many requests

Returned when rate limit is exceeded. Wait 60 seconds and retry. The Retry-After header indicates the wait time.

500 — Server error

Returned for unexpected errors. Should be rare. Retry the request; if it persists, contact hello@neodefender.com.
