## Short Answer

AI micro-tools can still be tested, but they should be treated as usage-metered products. A subscription plan or development credit is not the same as production API cost. Real budgeting must include model tokens, tool calls, search, containers, caching, batch processing, retry behavior, and hard usage limits.

## Best For

- Builders who can read API pricing pages and maintain a simple unit-cost table.
- Small tools with low call frequency, clear output boundaries, and daily user limits.
- Products where the first test can run with 30-50 real samples before launch.

## Avoid If

- The product depends on unlimited free users, long-running agents, image/video generation, or uncontrolled retries.
- The operator cannot separate development credits from production API billing.
- There is no logging, user-level quota, billing alert, or kill switch.

## Minimum Test

1. Pick one core task and cap each user at 3-5 uses per day.
2. Run 30-50 representative samples.
3. Record input tokens, output tokens, tool calls, retries, latency, and cost per successful result.
4. Compare the unit cost against the price a real user would pay.
5. Set budget limits, key permissions, alerts, and task-level cost tags before public release.

## Stop-Loss Signals

- Cost per successful task approaches or exceeds realistic revenue per task.
- Free users generate usage but no repeat use, share, signup, or payment signal.
- Cost controls make the result too weak to trust.
- Billing, logs, limits, and key management become harder than the product itself.
