+## Solicitando um Serviço de Correlação
+
+Given a file "intake-person-demo(age).csv" with the following file fields: age, gender, ethnicity, and fcid_code. Create a FastAPI service that has the following endpoint:
+
+GET /correlation
+
+This service receives the fcid_code of a food product. It returns the correlation between the age and intake_bw of the food product. The data to calculate the correlation comes from the csv file.

+## Passo 2 - Transformando Workflow em Componente
 
 Given a . Create a python class to execute logistic regression predictions with two operations:
 
 * train: Receives the csv file path file with the following file fields: age, gender, ethnicity, and fcid_code. Trains a logistic regression model to predict the fcid_code given age, gender, and ethnicity.
 * predict: Receives three parameters (age, gender, and ethnicity) and predicts the fcid_code with the logistic regression model.

+### Exemplo de uso
 
 Can you give me a example of code using this class to do predictions with the following parameters:
 * train: file path = "intake-person-demo(beans).csv"
 * predict: age=31; gender=1; ethnicity=2

+## Passo 3 - Componente para Serviço
 
 Can you transform this code into a FastAPI service with two endpoints:
 * POST /train
-* GET /predict
+* GET /predict
