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

```sh
zero fetch --capability x402-finance-hub-forex-time-series-7f70be25 -d '<json body>'
```

Example prompt: Can you pull the daily time series for EUR/USD for the last 100 data points so I can analyze the recent price trend?

## When to prefer this

Choose this endpoint when you need historical candlestick or OHLCV time series data for a specific forex pair and want to pay per-call with USDC on Base via the x402 protocol, avoiding subscription-based API keys. Ideal for agents doing backtesting, charting, or trend analysis on currency pairs.
