Frequently asked questions

What does the data source finder do?

Describe your use case for up to three sources with costs at your monthly volume, resale evidence and build-it-yourself guidance. Get an instant shortlist, then a full plan.

Is it really free?

Yes. The full plan and Markdown or HTML downloads are free, with no email or checkout. The web allows 60 full plans per IP per hour.

Can I resell the data?

Every source shows a resale answer, its recorded terms clause, URL and read date. Yes means under the licence terms; derived-only covers what you build, not raw data. Missing evidence is shown as unknown.

How is cost worked out?

We apply the recorded price rule to your monthly volume. Data access can be free while storage and processing cost extra. Unpublished or ambiguous prices stay unknown, never guessed.

Can AI agents use it through MCP and API?

Yes. Call find_data over MCP or GET /api/data-finder with q, volume, resell and geo. Agent tools are free: 20 calls a day per IP, no key needed.

Is anything stored?

No query text or plan is logged or stored. The shortlist runs in your browser. The full plan sends your answers to our server for calculation; only usage counts and IP rate limits are kept.
