Lotus Network API – Base L2 Gas Preflight
x402
Lotus Network API – Base L2 Gas Preflight is a paid API for AI agents from lotusnetworkapi.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).
Returns current Base L2 gas conditions (base fee, recent percentiles, volatility, congestion state) plus a probabilistic 80% forecast range for a chosen horizon in minutes.

How this service works
Read-only Base L2 gas conditions computed directly from chain data: current base fee, recent percentiles, realised volatility, congestion state, and an 80% forecast range for a chosen horizon. This is supporting context for timing a transaction, not a trade instruction. Every figure is reproducible from public Base RPC data.
Output
A JSON object containing: the current Base block number, observed timestamp, current base fee in Gwei, gas used ratio, congestion label; recent statistics (median, p10, p90 in Gwei, realised volatility, block count); and a forecast object (center, low, high Gwei estimates, target block, and interval) representing an 80% confidence range for the requested horizon.
Example use cases
DeFi transaction timing decision
“I'm about to execute a swap on Base — can you check the current gas conditions and forecast for the next 15 minutes so I can decide if now is a good time or if I should wait for fees to drop?”
Monitoring Base congestion before mint
“I have an NFT mint coming up on Base. Pull a gas preflight for the next 30 minutes — I need the congestion state, current base fee, and the low-to-high forecast range before I commit.”
Automated agent gas gating
“Before the agent submits that on-chain action, run a gas preflight on Base with a 10-minute horizon and tell me if the network is congested and what the p10 to p90 fee range looks like right now.”
Technical details
Endpoint
GEThttps://lotusnetworkapi.com/api/v1/gas/preflightWhen to prefer
Choose this endpoint when an AI agent needs real-time, statistically grounded Base L2 gas intelligence — especially when deciding whether to execute or defer a transaction. It is distinct from generic Ethereum mainnet gas APIs because it reads directly from Base chain RPC data and provides probabilistic forecast ranges with volatility context, not just a spot price. Prefer it over wallet-embedded gas estimators when the agent needs structured, machine-readable forecast data with percentile breakdowns.
Side effects
- Invalid horizonMinutes value outside 1–60 range returns a validation error
- RPC connectivity issues may cause stale or unavailable chain data
- If Base chain is experiencing an outage, the endpoint may return an error or degraded response
- Payment failure (x402 protocol) will block access before any data is returned
