## How to call it through Zero

```sh
zero fetch --capability moneylab-free-tier-limits-api-5ebd1b3a
```

Example prompt: What are the free tier limits for Suno — can I use the music commercially, does it watermark outputs, and has anything changed recently in their terms?

## When to prefer this

Choose this endpoint when you need structured, regularly-updated data on AI tool free tier limits, commercial rights, and ownership policies — especially when you need to compare across tools or detect recent policy changes. Prefer it over manually scraping terms-of-service pages when you need machine-readable policy data with confidence ratings and changelogs.

## Known failure modes

- Empty rows array if no tools match filter criteria
- Stale data if last_checked date is old and vendor has changed terms since
- Confidence field marked 'secondary' indicates terms inferred rather than directly stated
- Missing or null fields if specific policy details are not publicly documented
- HTTP 402 if payment not included or USDC balance insufficient
