How this service works
A directory of free and freemium tools for small businesses. Each listing quotes the vendor's own page and records the date we checked it.
Output
A JSON object containing a list of recommended tools ('stack' array) for the specified business type, along with the report identifier and business type echo. Each tool entry is sourced from vendor pages with a recorded check date, covering categories relevant to the business type requested.
Example use cases
Solo creator tool discovery
“I just started a creator business making online courses — can you pull a list of free tools I should be using? I don't want to pay for anything yet, just free options.”
Nonprofit software stack planning
“We're setting up a small nonprofit and need to know what free or freemium software tools we should be using. Can you get me a stack report for a nonprofit org?”
Retail shop ops setup
“I'm opening a small retail shop and want to see what free business tools are available for retail. Can you grab me a tool stack report? We're a team of 2.”

Endpoint
GEThttps://api.freesmallbiztools.com/v1/stack-report?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs a curated, up-to-date list of free or freemium tools tailored to a specific small business type. It is ideal for onboarding workflows, business setup assistants, or cost-reduction audits where the user wants vendor-vetted recommendations rather than generic web search results. Prefer this over general web search when structured, categorized tool data is needed with known freshness timestamps.
Side effects
- Missing required 'business_type' parameter returns a validation error
- Invalid 'business_type' value not in the allowed enum returns a 400-level error
- Payment failure (x402) if USDC is not sent or insufficient — endpoint returns 402 Payment Required
- Empty stack array returned if no tools match the combined filters (e.g., very restrictive needs + free_only)
- Stale tool data if vendor pages have changed since the last recorded check date
