Technical details
Endpoint
POSThttps://x402-echo-service.onrender.com/chain/gasWhen to prefer
Use this endpoint when you need a quick, pay-per-call read of current Base gas conditions without setting up your own RPC connection. Ideal for agents that gate transactions on fee thresholds or need to display current gas costs to users. Prefer over full node SDKs when you want a lightweight, metered lookup with no infrastructure overhead.
Side effects
- Base RPC node temporarily unavailable — endpoint may return a 5xx error
- Network congestion or timeout may cause delayed or failed responses
- Returned values reflect the latest block at time of call and may be stale by the time a transaction is broadcast
