onyx_retail_price_check

Active

declared in 1.26.0

Ground-truth retail oracle. Give a product URL; get the real current price, currency, and in-stock state as actually fetched now — with the extraction source (JSON-LD / OpenGraph / microdata) as evidence. Covers the long tail of no-API shops where agents otherwise hallucinate prices. Never guesses: returns price=None with confidence='none' when the page exposes no machine-readable price. Use before an agent quotes, compares, or transacts on a price it would otherwise invent. (price: $0.02 USDC, tier: metered)
