What problem does it solve?
Health and food agents invent nutrition numbers unless they call a verified USDA source and you still need a sane micropayment model for API costs.
Who is it for?
Indie builders prototyping nutrition coaches, macro trackers, or agent marketplaces that bill per tool invocation on Base.
Skip if: Static content sites with no agent runtime, or teams unwilling to handle crypto micropayments and wallet setup.
