How this service works
Per-provider RPC latency, head lag and error rates, last 15 minutes
Output
A structured response with per-provider metrics including: RPC call latency (ms), head lag (number of blocks or time behind chain tip), and error rates — all measured over the trailing 15-minute window. Allows direct comparison across multiple RPC providers.
Example use cases
Picking the fastest RPC for a dApp
“Which RPC provider is performing best right now in terms of latency and error rate? I'm about to run a batch of transactions and want to route through the healthiest node.”
Debugging slow blockchain queries
“My app feels sluggish — can you pull the RPC health stats for the last 15 minutes and tell me if any providers are showing high head lag or elevated error rates?”
Automated RPC failover monitoring
“Check the RPC health dashboard and alert me if any provider's error rate or head lag has spiked in the past 15 minutes — I want to know before it affects my users.”
Technical details
Endpoint
GEThttps://api.cra-agent.tech/v1/paid/rpc/healthWhen to prefer
Use this endpoint when you need a real-time, multi-provider comparison of RPC health metrics (latency, head lag, error rate) in a single call. Prefer it over manually pinging individual RPC endpoints or using generic uptime tools, especially when routing decisions depend on which provider is healthiest at this moment.
Side effects
- Payment not attached or insufficient USDC balance — 402 response
- No data available if all providers are unreachable
- Stale data if the aggregation pipeline is delayed
- Rate limiting if called too frequently
