How this service works
Lazareus gives AI agents pay-per-call S3-compatible storage, plus real-time network health scores and priority fee recommendations across Solana, Base, and Ethereum. No account, no subscription — paid per call via x402.
Output
Returns a recommended priority fee value (likely in Gwei or wei) for Ethereum transactions, reflecting current network congestion and mempool conditions, potentially alongside a network health score to indicate overall chain responsiveness.
Example use cases
Pre-transaction fee optimization
“Before I submit this Ethereum transaction, what priority fee do you recommend right now so it gets confirmed in the next block without overpaying?”
DeFi agent gas tuning
“My DeFi agent is about to execute a swap on Ethereum — can you check the current network health and tell me the recommended priority fee so I can set it correctly?”
Real-time Ethereum congestion check
“Is Ethereum congested right now, and what priority fee should my bot use to get transactions through reliably?”
Technical details
Endpoint
GEThttps://lazareus.xyz/get_recommended_priority_fee/ethereumWhen to prefer
Choose this endpoint when your AI agent needs to submit Ethereum transactions and wants a real-time, per-call fee recommendation without maintaining its own gas oracle. Particularly useful for autonomous agents that need to optimize transaction inclusion speed versus cost on Ethereum, and that already support the x402 micropayment protocol for per-call billing.
Side effects
- Network unavailable: Ethereum RPC node down or unreachable, resulting in an error or stale data
- Payment failure: x402 micropayment of $0.002 USDC not processed, request rejected
- Rate limiting: excessive calls from a single agent may be throttled
- Stale data: if the underlying fee oracle lags, recommendations may not reflect very recent mempool spikes
