Key patterns: 1. **Always use `--json`** for programmatic access 2. **Check exit codes** - 0 for success, 1 for error 3. **Use saved wallets** - Configure once with `onchain setup`, reference by name 4. **Rate limiting** - APIs have rate limits, add delays between rapid calls ### Example Agent Usage ```bash # Get portfolio value VALUE=$(onchain --json portfolio main | jq -r '.totalValueUsd') # Get price with change onchain --json price btc | jq '{price: .priceUsd, change24h: .priceChange24h}' # Check if market is bullish CHANGE=$(onchain --json markets | jq '.marketCapChange24h') ```
