RPC for Trading Bots & Onchain Execution
Trading bots live or die on latency and reliability. A throttled or laggy RPC means missed fills, stale quotes, and failed transactions — usually right when volume spikes and it matters most.
Where public RPC falls short
- Public endpoints rate-limit aggressively — your bot starts getting 429s exactly during the volatility you're trying to trade.
- US-centric providers add round-trip latency if your infrastructure runs elsewhere.
- A single endpoint degrading mid-strategy means missed opportunities and stuck transactions.
How NodeFlare handles it
Nearest-region routing
Requests follow configured regional preferences. Base, Arbitrum and BNB Chain have primary nodes in 5 regions, which shortens the round trip on your hot path when you run near one of them.
Published rate limits
Paid plans give you your full compute-unit budget within their published requests-per-second limits.
Automatic failover
If a node degrades, the next healthy one takes over before your bot notices.
WebSocket subscriptions
Subscribe to new heads and pending state over WSS for the fastest possible signals.

FAQ
Is there a rate limit for trading bots?
The public endpoint is rate-limited per IP. The keyless endpoint allows 1 request per 10 seconds. Paid keys scale from 50 to 1,500 requests/second with published per-plan rate limits, so your budget is there when you need it.
Do you support WebSocket subscriptions?
Yes, on Ethereum, Base, BNB Chain, Arbitrum, Optimism, HyperEVM and Avalanche (wss://rpc.nodeflare.app/{chain}/ws/v1/{key}) for newHeads and other subscriptions. The other chains are HTTP only.
Which regions do you run in?
Our own bare-metal nodes across US-East, US-West, EU and Asia. Base, Arbitrum and BNB Chain have primary nodes in 5 regions; most other chains have one or two. The gateway routes each request by configured regional preference and fails over to another region when a node is unhealthy, so the benefit depends on the chain and on where your bot runs.
