Reduce time to monetize your API.

We expand the API spec to add a cost field with price in terms of API credits and a translation for cost per credit. We also add an encrypted config to store your Stripe API Key.

Users can:

1. Create an API Key
2. Delete an API Key. Money is returned to the user account.
3. Add money to an API Key
4. Monitor their API credits remaining and the requests they made and how much each cost
5. Get response from an API if API Key has credits remaining. Otherwise error 'too few credits.'

1. Start the API:

uvicorn gringotts.main:app

2. Create a user and API key:

from gringotts import auth, db
db_session = db.SessionLocal()
user, api_key = auth.create_user_with_key(db_session, "alice", credits=5)
print(api_key)

3. Call the protected endpoint:

curl -X POST "http://localhost:8000/predict" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $API_KEY" \
  -d '{"input_string": "hello"}'

Install dependencies and run the test suite:

python -m venv venv
source venv/bin/activate
pip install -r gringotts/requirements.txt
pytest -q

Manage users and credits from the command line:

python -m gringotts.cli create-user alice --credits 5
python -m gringotts.cli add-credits alice 3
