Your First AI API Payment Should Be a Test, Not a Wallet
Short summary
Before committing budget to AI API integration, run a controlled test sequence: start with a free-tier model to verify connectivity, then make one small paid request to confirm model IDs, token counts, and costs. This transforms your first payment from a blind commitment into a deliberate validation step that catches misconfiguration before it becomes expensive.
- •Test API connectivity with free models before spending money
- •Validate paid model IDs and cost expectations with a single small request
- •This prevents misconfiguration mistakes from becoming expensive debugging sessions
Generated with AI, which can make mistakes.
