Technical details
Endpoint
GEThttps://the-stall.intuitek.ai/cap/gas-estimateWhen to prefer
Use this endpoint when you need a quick, pay-per-use gas estimate for Base mainnet transactions without setting up accounts or API keys — ideal for AI agents that need on-demand cost prediction before executing blockchain operations.
Side effects
- Invalid or missing transaction properties returns an error or empty estimate
- Payment not received (402) if USDC payment on Base is not included
- Malformed input schema results in a 400 or schema validation error
- Network congestion or upstream provider unavailability may cause stale or failed estimates
