Claude and GPT: API Credit or web subscription?
Claude Pro, ChatGPT Plus and AI APIs solve different problems. This guide helps you choose the right Ezkielyna product without confusing an API key with a web login.
| Need | Better fit | Why |
|---|---|---|
| Coding agent, bot or app | API Credit | Programmable endpoint and usage logs |
| Chat in a provider website | Web subscription | Provider UI, projects and account features |
| Several models in one project | Ezkielyna API | One key and model IDs from the live catalog |
What API Credit includes
Ezkielyna API Credit is prepaid usage balance. It can be used with the models currently listed on the live Model Square, subject to key-group availability and the model's published billing unit. It is not a shared ChatGPT or Claude password.
How to keep costs predictable
- Use a separate API key per app or project.
- Set a spending limit where the dashboard supports it.
- Choose the exact model ID and monitor Usage Logs.
- Keep prompts concise and use caching where supported.
- Check the live price before launching a new workload.
A note about access and warranties
Web accounts and digital products have product-specific access rules and warranty terms. Read the listing before checkout. Do not use shared accounts for confidential material, and never send passwords or API keys to support.
