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
Every request is geo-routed to your nearest region — Base and Arbitrum run in 5 regions, BNB in 4 — shaving round-trip time off your hot path.
No per-request throttling
Paid plans give you your full compute-unit budget without artificial per-second throttling.
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. Paid keys scale from 50 to 500 requests/second with no per-request throttling, so your budget is there when you need it.
Do you support WebSocket subscriptions?
Yes — every chain has a WSS endpoint (wss://rpc.nodeflare.app/{chain}/ws/v1/{key}) for newHeads and other subscriptions.
Which regions do you run in?
Our own bare-metal nodes across US-East, US-West, EU and Asia — Base and Arbitrum in 5 regions, BNB in 4. The gateway reads the Cloudflare edge location of each request and routes it to the nearest healthy node, with automatic failover. A bot in Singapore hits our Singapore node, not one in the US.
