What to check before buying
- Test the key with the free API checker — it verifies the endpoint responds, without sending tokens.
- Compare the blended cost for your workload, not just the input price: output tokens dominate in agent workloads.
- Check uptime and minimum top-up: the cheapest provider is useless if it is down half the day.
