## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability prereason-silver-market-briefing-2aa0cba2
```

Example prompt: Pull me today's silver market briefing — I want SLV price, the World Bank silver price per troy ounce, CFTC speculator net positions in COMEX silver futures, gold-silver ratio, 10-year real rate, and the correlated ETFs (GLD, UUP, SIL, CPER), formatted as JSON.

## When to prefer this

Choose this endpoint when you need a pre-aggregated, multi-metric silver market briefing that combines ETF pricing, World Bank commodity prices, CFTC positioning data, and macro correlators (real rates, dollar, copper) in a single call. Ideal for AI agents that need LLM-ready markdown output or structured JSON for silver market analysis without assembling data from multiple sources. Prefer over raw data APIs when you need correlated context (gold-silver ratio, real rate, speculator positioning) alongside spot price.

## Known failure modes

- Invalid date format (not YYYY-MM-DD) returns validation error
- Date requested has no data on record returns empty or error response
- Invalid format parameter returns error
- Payment not completed (x402) blocks access to the response
- Network timeout or upstream data source unavailability may return 5xx error

## How this service works

Silver through the silver fund and silver's own price. SLV's share price and the World Bank's monthly average silver price per troy ounce, speculators' net position in COMEX silver futures (CFTC), and the gold fund, the 10 year real Treasury rate, the dollar, copper and silver miners' funds beside it, each with its measured relationship to SLV. Commodity market data for research agents. A paid call serves today or any ?date= on record.

## Output

Returns a structured briefing with up to 10 named metrics including SLV ETF price, World Bank monthly silver price (USD per troy ounce), CFTC non-commercial net position in COMEX silver futures, gold-silver ratio, SLV/SIL ratio, 10-year real rate, and prices for correlated ETFs (GLD, UUP, CPER, SIL). Also includes briefing metadata with description, metric count, and correlation count. Available in JSON or LLM-optimized markdown format.
