```sh
zero fetch --capability losbeto-mempool-data-endpoint-170c8c48
```

Example prompt: Can you pull the current mempool data from Losbeto so I can see what transactions are pending on-chain right now?

## When to prefer this

Choose this endpoint when you need real-time mempool visibility for Solana or Base networks and are operating within an x402 micropayment-capable agent framework. Particularly useful for MEV analysis, pre-trade latency checks, or network congestion assessment at a very low per-call cost of $0.008 USDC.

## Known failure modes

- Payment not included or insufficient USDC (HTTP 402) — requires $0.008 USDC per call via x402 protocol
- Mempool data temporarily unavailable due to node connectivity issues
- Empty mempool response during low-activity network periods
- Malformed properties filter parameter returns schema error
- Railway hosting downtime causes 503 service unavailable
