## Short Answer

AI micro-tools are still testable, but the budget can no longer be a single AI subscription. If a product uses an API, Agent SDK, search grounding, long context, image generation, containers, or retries, the real risk is usage-based spend, exhausted credits, and abuse control.

## Best For

- Builders who can read pricing pages and maintain a unit-cost sheet.
- One-task tools with clear run limits and measurable cost per successful result.
- Operators who can separate build-time credits from production runtime cost.

## Avoid If

- The product depends on unlimited free trials, always-on agents, bulk generation, or scraping loops.
- There are no per-user quotas, task-level cost tags, budget alerts, scoped keys, or kill switches.
- Revenue assumptions are based on screenshots or tutorials rather than user behavior.

## Minimum Test

1. Build one core task.
2. Limit each user to 3-5 runs per day.
3. Run 30-50 real examples.
4. Log input tokens, output tokens, retries, search calls, tool calls, latency, and total cost.
5. Compare cost, output quality, and willingness to pay before productizing.

## Stop-Loss Signals

- One complete task costs close to what a user would pay.
- Free users run many jobs but do not return, share, sign up, or pay.
- Cost controls weaken the output until it is no longer reliable.
- Billing, logs, quotas, and key management exceed maintenance capacity.
