How this service works
Live Solana network conditions: pending transaction pressure, current fee levels and priority-fee guidance for agents timing an execution.
Output
Returns a JSON object containing current mempool state including pending/unconfirmed transactions visible in the blockchain mempool, likely including transaction hashes, fee data, sizes, and queue depth relevant for trading decisions.
Example use cases
AI trading bot mempool signal
“Pull the current mempool state so my trading bot can spot large pending transactions before they confirm and decide whether to front-run or wait.”
DeFi arbitrage opportunity detection
“Fetch the mempool right now and look for any pending swaps or large trades that might create a price arbitrage window I can act on.”
Network congestion monitoring
“Check the mempool and tell me how congested the network is — I want to know if there are a lot of pending transactions piling up before I submit mine.”
Technical details
Endpoint
GEThttps://api.losbeto.xyz/mempool?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time mempool visibility for an AI trading agent operating on Solana or Base chains, especially when you want micropayment-per-call pricing ($0.008 USDC) rather than a subscription. Best suited for agents that need sporadic or event-driven mempool snapshots rather than continuous streaming.
Side effects
- Missing or invalid x402 payment header returns 402 Payment Required
- Malformed properties filter parameter may return 400 Bad Request
- Network or upstream blockchain node unavailability may return 503 or empty response
- Expired or insufficient USDC payment results in access denial
- Rate limiting if too many calls are made in quick succession
