How this service works
Copper through a copper futures fund. CPER's share price and the World Bank's monthly average LME copper price per metric ton, speculators' net position in COMEX copper futures (CFTC), and the dollar and gold funds beside it, each with its measured relationship to CPER. Commodity market data for research agents. A paid call serves today or any ?date= on record.
Output
Returns a structured briefing with 6 metrics: CPER ETF price, UUP dollar ETF, GLD gold ETF, World Bank monthly LME copper price (USD per metric ton), copper-gold ratio, and CFTC non-commercial net position in COMEX copper futures, along with correlation data between these series. Available in JSON (structured) or markdown (token-optimized for LLMs).
Example use cases
Daily copper market briefing for traders
“Give me today's copper market snapshot — CPER share price, World Bank LME copper price per metric ton, and where speculators are net positioned in COMEX copper futures.”
Historical copper positioning research
“Pull the copper market data for 2024-09-15 — I want the CFTC non-commercial net position, the copper-gold ratio, and the World Bank copper price for that date in JSON format.”
Macro cross-asset copper analysis
“I'm building a macro report — fetch me the latest copper briefing showing how CPER correlates with the dollar index ETF and gold, plus the current speculator positioning from the COT report.”
Technical details
Endpoint
GEThttps://api.prereason.com/api/commodities/copper?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pre-assembled, multi-signal copper market briefing that combines ETF pricing (CPER), World Bank LME reference pricing, CFTC speculator positioning, and cross-asset correlations with gold and the dollar in a single call. Ideal for macro research agents, commodities dashboards, or LLM-native workflows that need token-optimized markdown output. Prefer over raw commodity data feeds when you want pre-computed correlations and a curated set of copper-relevant signals without assembling multiple data sources yourself.
Side effects
- Date not found in historical record — requested ?date= may be outside available data range
- Invalid date format — must match YYYY-MM-DD pattern
- Payment not processed — x402 micropayment of $0.03 USDC required per call
- World Bank monthly copper price may lag by several weeks for recent months
- Network timeout or upstream data source unavailable
