## 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 agents-x402stock-xyz-crypto-spot-pair-previous-day-ohlcv-x402stock-7af8eef2
```

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

## When to prefer this

Use this endpoint when you need exactly yesterday's UTC daily bar (00:00–24:00 UTC) for a crypto spot pair in a single low-cost call ($0.01 USDC). Prefer this over historical bar endpoints when you only need the most recent completed day and don't want to specify date parameters. Ideal for daily portfolio tracking, end-of-day reporting, or feeding yesterday's price into a downstream calculation.

## Known failure modes

- Unsupported or misspelled pair returns null data field
- Invalid pair format (not BASE-QUOTE) may cause error or null response
- Data unavailable for thinly traded or unsupported pairs
- Payment failure via x402 if insufficient USDC balance

## 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 JSON object containing the ticker symbol, yesterday's OHLCV data (open, high, low, close, volume, VWAP, trade count, timestamp), the as_of date string, and a source field identifying x402stock. The data field may be null if no data is available for the pair.
