OpenAI-compatible LLM gateway at $0.005/call — change base_url, pay in USDC. Plus pay-per-call market data: multi-oracle price consensus, sentiment, forex, equities, commodities, Brazil macro (BCB/B3) and crypto. No API keys, no accounts. USDC on Base, Solana, Algorand and Polygon via x402.
Output
Returns a JSON object containing current mempool data including pending transactions, their statuses, and relevant blockchain state across Solana and/or Base networks, useful for trading signal generation and transaction timing decisions.
Example use cases
MEV arbitrage signal detection
“Check the mempool right now and tell me if there are any large pending swaps on Base that I could front-run or sandwich for an arbitrage trade.”
Pre-trade liquidity check
“Before I execute my USDC trade, pull the current mempool state so I can see how congested Base is and whether my transaction will go through quickly.”
AI trading bot mempool feed
“My trading agent needs a live mempool snapshot from Losbeto every 30 seconds to detect pending whale transactions on Solana — can you fetch the latest one now?”
