Throughput

What is throughput?

“Throughput” is the volume of requests your application can successfully send to Conduit RPC gateways within a period of time. Limits are enforced in Compute Units per second (CU/s), learn more.

Current limits

Additional limits:

Method-specific limits

When using the indexed logs backend:

• eth_getLogs: up to 10,000 log events per request
• eth_getLogs block range: up to 2,000 blocks per request

Tips for eth_getLogs:

• Page by block range (for example, chunks of ≤2,000 blocks) and by topics to keep event counts below limits
• Prefer stable block tags (for example, a specific block number) when possible
• Requesting more than 10,000 logs fails with HTTP 400 (error code -32005). Example response:

  1
  {
  2
    "jsonrpc": "2.0",
  3
    "error": {
  4
      "code": -32005,
  5
      "message": "logs count limit exceeded (10000) consider refine/narrow down your query"
  6
    },
  7
    "id": 0
  8
  }

eth_getProof limits

On OP Stack networks, eth_getProof is limited to a recent history window. Requests for deep historical state are not served. This limit exists to prevent denial-of-service on the Reth v2 node backend.

• Proofs for recent and latest blocks are unaffected
• Katana networks are not affected
• If you need a larger history window, see Archive Node Access for options

Handling 429 (rate limited)

If you receive HTTP 429:

• Back off and retry with exponential backoff and jitter; honor Retry-After if present
• Reduce concurrency; queue or rate limit at the client
• Use batch requests to reduce overhead (stay under 5 MB)
• Prefer WebSocket subscriptions for high-frequency event use cases
• For large log scans, paginate ranges rather than one wide query

Best practices

• Understand method cost: some methods are heavier than others. See Compute Units
• Batch sensibly: group similar calls into a single batch where appropriate
• Cache read results and pin to specific block numbers when possible to avoid repeated work
• Use separate API keys per environment and service to isolate traffic. See Get an API key and Access Control & Settings

Increasing limits

Upgrade your plan or contact Conduit for higher limits:

• See Pricing & Costs
• Pro and Enterprise plans support significantly higher sustained throughput
