## 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 claw402-metals-time-series-via-twelve-data-0c76f04b
```

Example prompt: Can you pull the daily gold (XAU) price history from January 1 to June 30 2024, using a 1-day interval and 180 data points?

## When to prefer this

Use this endpoint when you need historical precious metals price data (gold, silver, platinum, etc.) and want to avoid API key registration — ideal for autonomous AI agents that pay per-call with USDC via the x402 protocol. Prefer this over direct Twelve Data access when keyless, wallet-based micropayments are needed.

## Known failure modes

- Invalid or unsupported metal symbol returns empty data array
- Missing required query parameters (symbol, interval) returns error
- Insufficient USDC balance or failed x402 payment returns 402 Payment Required
- Date range produces no data (e.g. weekends/holidays) returns empty array
- Malformed date format (start_date/end_date) may return an error or empty result

## How this service works

Backed by vergex.trade. Pay for any API with USDC. No API keys. No registration. Just a wallet.

## Output

A JSON object with a status code and an array of time-series entries containing OHLCV (open, high, low, close, volume) data points for the requested metal symbol over the specified date range and interval.
