Why this may sell before a full SaaS does

No login, subscription, OAuth app, or workspace setup.
Each result is a small artifact someone can paste into an invoice, DAO review, client update, agent workflow, or issue report.
Pricing is low enough for one-off pain: cents instead of a monthly tool decision.
