Transparent plans
Evaluate on the edge. Accelerate on your device.
The free tier is intentionally small enough for integration testing. Pro adds the persistent WebSocket and localhost accelerator for production-oriented workloads.
Free
$0
- 10 calls per minute

- Read-only Ethereum MCP server
- Reorg-aware cache and diagnostics
- Manual renewal; no silent auto-charge
Measured boundary
1.55ms warm p50 in the published proof. Cold reads still pay upstream latency. Performance depends on machine, workload, cache state, and network.

Is Pro unlimited?
No. The published envelope is 300 logical calls per 10 seconds. Local warm hits can execute faster, but service quotas still protect shared infrastructure.
Does Pro renew automatically?
No. The current USDC checkout activates Pro for 30 days and must be renewed manually.
Does the free tier include the localhost accelerator?
No. It is an edge-only evaluation tier.
Does low latency guarantee MEV profit?
No. Profit depends on strategy, competition, inclusion, gas, liquidity, execution correctness, and market conditions.
