## 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 x402stock-crypto-previous-day-ohlcv-512c88d0
```

Example prompt: What was yesterday's full daily candle for BTC-USD — open, high, low, close, volume, and VWAP?

## When to prefer this

Use this endpoint when you need a single, clean previous-day OHLCV daily candle for a spot crypto pair without requiring an API key — ideal for agents that need per-request, pay-as-you-go crypto market data. Prefer this over full historical endpoints when you only need yesterday's bar, and over subscription-based APIs when usage is infrequent or unpredictable.

## Known failure modes

- Invalid pair format (not BASE-QUOTE) returns an error
- Unsupported or illiquid pair returns no data or 404
- Payment failure via x402 if insufficient USDC balance
- Network timeout for slow upstream data providers
- Weekend/holiday data may still return (crypto trades 24/7)

## How this service works

Crypto trades 24/7, so there is no session close: this returns the previous UTC calendar day's full OHLCV candle (00:00–24:00 UTC) for a spot pair — open, high, low, close, volume, and VWAP. Pass the pair in the path as BASE-QUOTE, e.g. BTC-USD. One call returns yesterday's daily bar. From x402stock, a pay-per-call market & economic data API. Pay per request in USDC via x402, no API key.

## Output

A single daily OHLCV candle for the requested spot crypto pair covering the previous full UTC calendar day (00:00–24:00 UTC), including open, high, low, close prices, total traded volume, and volume-weighted average price (VWAP).
