How this service works
Dated, sourced answers to "can I use this AI tool commercially on the free plan?" for 44 image, voice, music and video tools: exact free-tier limits, commercial yes/no/unclear, cheapest commercial plan, output ownership, attribution, watermark, every vendor source URL, confidence level and a dated change log. Rows older than 45 days are flagged stale. The one-line answers are free at /data/free-ai-tools-commercial-use.json.
Output
Returns a JSON object with an array of tool records (each including tool name, category, free tier existence flag, credit/download limits, watermark policy, output ownership, attribution requirements, commercial use on free tier, paid entry price in USD/month, confidence level, source terms URLs, and last checked date) plus a changelog array of recent policy changes with date, tool, change type, and description.
Example use cases
Checking commercial rights before publishing
“I'm about to publish a YouTube video with AI-generated background music from Suno's free tier — can you check if I'm allowed to use it commercially and whether there's any watermark or attribution required?”
Comparing free AI tool policies for a content creator
“I want to find AI tools in the music or image category where the free tier actually lets me use the output commercially — can you pull the free tier limits and commercial use rights for all the tools you have data on?”
Monitoring AI tool terms for recent changes
“Have any AI tools recently changed their free tier rules or download limits? I want to know about any vendor changes in the last few months so I don't get caught out.”
Technical details
Endpoint
GEThttps://money-lab.app/api/agent/free-tier-limits?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
