## 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-futures-ohlcvt-candles-with-technical-indicators-86161fb1
```

Example prompt: Fetch the last 100 hourly candles for BTC with technical indicators — I need RSI, EMA20, EMA50, ATR, and whether it's in a support/resistance zone right now.

## When to prefer this

Choose this endpoint when your AI trading agent needs OHLCVT candles bundled with pre-computed technical indicators (RSI, EMA, ATR, trend zone) in a single call, without managing an API key or exchange subscription. Ideal for lightweight pay-per-use agents that don't need a persistent data feed. Prefer over raw exchange APIs when you want indicator enrichment included and are already using x402 micropayments on Base. Not suited for tick-level streaming or order execution.

## Known failure modes

- Invalid or unsupported symbol returns error response
- Interval enum value not in allowed set (1m,5m,15m,1h,4h,1d) causes rejection
- Limit out of range (must be 10–500) returns validation error
- Payment failure or insufficient USDC balance causes x402 payment-required response
- Upstream exchange (Binance) outage may cause delayed or empty candle data
- Very short intervals with high limits may hit upstream rate limits

## How this service works

Pay-per-call crypto microdata for trading/onchain AI agents via x402 (USDC on Base): Base gas, token risk, balances, multi-venue prices, Hyperliquid book/funding, kimchi premium. No API keys.

## Output
