How this service works
Melt value of gold, silver or platinum jewelry from weight, karat or fineness and the spot price per troy ounce you supply.
Output
Returns melt value in the caller's currency, along with a breakdown of pure metal weight (grams, pennyweights, troy ounces), purity percentage derived from karat or fineness, melt value per gram of the whole piece, and optionally a discounted melt value at a given payout percentage. Also includes an 'asOf' timestamp and source/disclaimer fields.
Example use cases
Scrap jewelry liquidation pricing
“I have a 14k gold bracelet that weighs 12 grams and gold spot is $3,150 per troy ounce — what's the melt value, and what would I actually get if a buyer pays 80% of melt?”
Silver flatware scrap valuation
“I want to know the melt value of a 925 sterling silver piece that weighs 85 grams. Silver is at $31.50 per troy ounce right now. What's it worth as scrap?”
Jewelry maker metal cost check
“I'm casting a platinum piece — the wax model came in at 9 grams and it's 950 fineness platinum. With platinum at $980 per troy ounce, what will the metal content alone be worth?”
Technical details
Endpoint
GEThttps://jewelry-calc.x402tookit.com/melt-value?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, formula-based melt value computation and you already have a current spot price from a market data source. It is ideal for jewelry resale agents, estate valuation tools, scrap metal buyers, and jewelry makers who need the raw metal cost of a piece. Prefer this over general-purpose LLM math when you need structured per-field breakdowns (pure metal weight, purity percent, payout-adjusted value) without hallucination risk.
Side effects
- Missing required 'grams' parameter causes a 400-class error
- Missing 'spotPerTroyOunce' returns an error since no built-in spot price exists
- Neither 'karat' nor 'fineness' supplied may produce a null or error result
- Karat value out of 1–24 range or fineness out of 0–1000 may be rejected or return unexpected purity
- Invalid weightUnit string may fall back to grams or return an error
- Payment failure (x402) returns 402 before any calculation is attempted
