Endpoint
GEThttps://apexrunner.ai/signals/slippage-forecastWhen to prefer

- size_usd below minimum ($10) or above maximum ($1,000,000) returns parameter error
- Payment of 2.1 USDC not completed results in 402 Payment Required
- Signal may expire quickly (valid_for_seconds) and must be re-fetched for live trading
- Network or service unavailability returns 5xx error
