## 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 crypto-ohlcvt-candle-data-with-technical-indicators-ce2d4cb2
```

Example prompt: Fetch the last 100 hourly OHLCVT candles for BTC and include RSI, EMA, ATR, and trend direction so I can see if it's in a support zone.

## When to prefer this

Choose this endpoint when an AI trading agent or DeFi bot needs candlestick price history bundled with pre-computed technical indicators (RSI, EMA, ATR, trend, zone) in a single pay-per-call request without API key setup. Ideal for lightweight autonomous agents that need fast, actionable market structure data for BTC, ETH, SOL or any USDT pair, billed in USDC micropayments via x402 — no subscription required.

## Known failure modes

- Invalid symbol returns error or empty candle set
- Unsupported interval enum value returns 400-level error
- Limit outside 10–500 range rejected by schema
- Payment failure via x402 (insufficient USDC balance) blocks the call
- Upstream Binance data unavailability may cause stale or empty response
- Network timeout on Cloudflare Worker edge
