Postman

Import the collection and test in minutes.

Create an account and a key in the dashboard (messy_test_… recommended).
In Postman choose Import → Link and paste https://messyapi.com/docs/postman.json, or download the file.
Set the API key collection variable.
Send POST /api/v1/normalize.

Importing into RapidAPI instead? Use the RapidAPI OpenAPI file. RapidAPI handles authentication, so don't send a MessyAPI key there.

Try it

curl -X POST https://messyapi.com/api/v1/repair \
  -H "Authorization: Bearer $MESSYAPI_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "records": [
    {
      "Company Name": "ACME, INC.",
      "Email": " JOHN@ACME.COM "
    }
  ]
}'
