How this service works
27 paid endpoints for trading bots
Output
Returns a predicted gas price (in gwei or wei) for a specified block horizon, along with a confidence score, recommended gas limit, estimated confirmation time, and a directional trend indicator (rising/falling/stable). Enables trading bots to make cost-aware transaction submission decisions.
Example use cases
Arbitrage bot transaction timing
“My arbitrage bot is about to execute a trade on Ethereum — predict the gas price for the next 3 blocks so it can pick the cheapest slot without getting front-run.”
DeFi liquidation cost estimation
“I'm running a liquidation bot and need a gas price forecast for the next 10 blocks on mainnet so I can decide whether the liquidation profit covers the gas cost.”
NFT mint gas optimization
“There's an NFT mint dropping soon — can you predict what gas prices will look like in the next 2 blocks so I know whether to mint now or wait a few minutes?”
Technical details
Endpoint
POSThttps://x402-chain-intel.vercel.app/api/gas/predict?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need forward-looking gas price estimates rather than current spot prices, especially for latency-sensitive trading bots that need to pre-calculate transaction costs across multiple upcoming blocks. It is particularly suited for DeFi bots, arbitrage engines, and liquidation bots operating on EVM-compatible chains where gas cost directly affects trade profitability.
