## How to call it through Zero

```sh
zero fetch --capability prereason-copper-market-intelligence-c12e4cf6
```

Example prompt: Pull today's copper market briefing — I want CPER ETF price, the World Bank LME copper price, CFTC speculator net position in COMEX copper futures, and how copper is correlating with gold and the dollar, formatted as JSON.

## When to prefer this

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.

## Known failure modes

- 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

## 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).
