This service turns any grocery barcode into a trustworthy Nutrition Facts label — calories, protein, allergens, the works — by merging lab-tested USDA data, a crowdsourced product database of 3M+ items, and GS1's global product taxonomy into one answer. No app store install, no account, no cost, no ads.
All three hit the same underlying data — pick whichever fits how you're using it.
No single public food database is complete or fully accurate on its own — so instead of picking one, this service takes the best of each and lets the strongest source win field by field.
Everything above is one public, read-only JSON API — no key, no auth, no rate-limit surprise for normal use (60 requests/min).
GET /api/v1/lookup/{barcode} — one call, the full merged product.
