## 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 x402-finance-hub-stock-time-series-b92e701c -d '<json body>'
```

Example prompt: Pull the last 100 daily candlesticks for AAPL — I need the open, high, low, close, and volume so I can run a backtest.

## When to prefer this

Use this endpoint when you need historical OHLCV time-series data for a specific stock symbol and are comfortable paying $0.1 USDC per call via the x402 protocol on Base. Prefer this over free alternatives when you need reliable, multi-provider coverage (Alpha Vantage + Twelve Data) or when building trading pipelines that require on-demand market data with crypto micropayments.

## Known failure modes

- Invalid or unknown stock symbol returns an error or empty data object
- Unsupported interval value may return an error or default behavior
- Payment of 0.1 USDC on Base not completed results in 402 Payment Required
- Rate limit or upstream provider outage causes 5xx error
- Missing required 'symbol' field returns a 400 validation error

## How this service works

Forex, stocks, crypto, and trading data from Alpha Vantage, Twelve Data, TradingView, and Forex Factory. Pay with USDC on Base.
