How this service works
Monthly world reference prices for copper, aluminium and zinc from FRED (World Bank series, USD). These are not LME cash-settlement prices; the name is kept for the route. Latest value plus up to 24 months of history.
Output
A JSON object with three metal keys (copper, aluminium, zinc), each containing a unit label ('USD per metric ton'), the latest price with its date, and an array of monthly historical price objects. Also includes the FRED source URL and a checkedAt timestamp indicating when the data was last fetched.
Example use cases
Manufacturing cost baseline tracking
“I need the latest World Bank monthly reference prices for copper, aluminium, and zinc — pull the last 6 months of history so I can update our raw material cost model.”
Commodity trend report for investors
“Can you get me 24 months of historical monthly prices for copper, aluminium, and zinc from the FRED World Bank series so I can chart the trends for our quarterly metals report?”
Supply chain pricing alert
“What are the current World Bank reference prices for copper and zinc this month? Just the latest values — I want to see if we've crossed a key threshold.”
Technical details
Endpoint
GEThttps://api.tradeenergy-api.workers.dev/api/energy/lme-metal-cash-settled?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need World Bank monthly commodity benchmark prices specifically for copper, aluminium, and zinc sourced from FRED — ideal for trade economics, manufacturing cost analysis, or commodity research workflows. Prefer it over LME-specific APIs when World Bank reference prices (not live exchange settlement prices) are the required data source. Use sibling endpoints for agricultural commodities (corn, wheat, soybeans), energy products (jet fuel, uranium), or other commodity classes.
Side effects
- Invalid months parameter (outside 1–24 range) may return an error or default to 3 months
- FRED upstream unavailability may cause stale or missing data
- Network timeout from the Cloudflare Worker if FRED is slow
- Payment failure (x402 protocol) if USDC balance is insufficient
