## 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`):

Example prompt: What are the available USDT trading pairs on Binance right now, and can you pull the last 24 hours of 1-hour candlestick data for BTC/USDT?

## When to prefer this

Choose this endpoint when you need conversational, natural-language access to Binance market data — including live symbols, market metadata, and historical candlesticks — without building a direct Binance API integration. Ideal for agents that need to answer ad-hoc crypto market questions, populate dashboards, or gather OHLCV data for analysis, especially when a pay-per-call model ($0.005 USDC) is preferable to managing API keys.

## Known failure modes

- Ambiguous question may return a generic explanation of service rather than specific data
- Unknown or delisted symbol may return empty results or an error
- Rate limits may cause failures during high-frequency querying
- Binance API downtime propagates as unavailable data
- Malformed question strings may yield unhelpful responses
