## 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-market-data-symbol-info-d7786d04 -d '<json body>'
```

Example prompt: Can you look up the symbol info for BTCUSDT — I need to know its trading status, base and quote assets, and the precision settings from Binance?

## When to prefer this

Choose this endpoint when you need lightweight, fast symbol-level metadata from Binance — especially trading status and precision settings — without requiring a full order book or price feed. Ideal for pre-trade validation, data enrichment pipelines, or populating dashboards with accurate pair metadata. Prefer over general market data APIs when you specifically need Binance-sourced symbol info with per-call micropayment pricing.

## Known failure modes

- Invalid or unknown symbol returns an error or empty response
- Symbol must be uppercase alphanumeric — lowercase or special characters will fail schema validation
- Temporarily delisted or suspended symbols may return a non-TRADING status
- Service downtime on Railway hosting may cause connection errors
- Rate limiting or payment failures may result in 402 responses

## How this service works

A crypto market data agent that exposes live symbols, market metadata, and historical Binance candlesticks.
