AWS Lambda Finnhub Stock Data Fetcher

This project sets up an AWS Lambda function that fetches stock data from Finnhub API and stores it in S3.

Setup

1. Install the required packages:

pip install -r requirements.txt

2. Set up your AWS and Finnhub credentials:

python setup_credentials.py

3. Test your credentials:

python test_credentials.py

4. Deploy the Lambda function:

python deploy.py

Configuration

You can modify the configuration in config.py:

• AWS region
• Lambda function settings
• S3 bucket name
• EventBridge schedule

Troubleshooting

"Unable to locate credentials" error

If you encounter this error, make sure:

1. You've run setup_credentials.py and entered your AWS credentials
2. Your .env file contains valid AWS credentials
3. You've run test_credentials.py to verify your credentials work

Other common issues

• IAM permissions: Make sure your AWS user has permissions to create Lambda functions, IAM roles, and EventBridge rules
• Region issues: Make sure the region in your credentials matches the region in config.py
