Thanks for using our RPC infra. Here are some details:

• We don’t support confirmed commitment level for the following methods:
  • getProgramAccounts
  • getTokenLargestAccounts
  • getTokenAccountsByOwner
• getTokenLargestAccounts returns the top 200 accounts instead of 20
• getProgramAccounts returns at most 100,000 accounts per call
• getProgramAccounts for program 9xQeWvG816bUx9EPjHmaT23yvVM2ZWbrrpZb9PusVFin (Serum DEX V3) is not supported in the initial release (let us know if you really need this!)
• For more details about the method calls please refer to the Solana documentation

How fast is our API?

You can try it out yourself. The following request fetches the hashlist for an NFT project.

curl <https://rpc.theindex.io> -X POST -H "Content-Type: application/json" -d '{
  "method": "getProgramAccounts",
  "jsonrpc": "2.0",
  "params": [
    "metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s",
    {
			"commitment": "finalized",
      "encoding": "base64",
      "filters": [
        {
          "memcmp": {
            "offset": 326,
            "bytes": "B9REbEXGse3JD2EtypAt2rDwPniA57AtPMCQ8n4WfYnK"
          }
        },
        {
          "memcmp": {
            "offset": 358,
            "bytes": "2"
          }
        }
      ]
    }
  ],
  "id": "speed-test"
}'

This takes around a full minute on other RPC providers but we respond in ~5 seconds 😉

<aside> ⚠️ Although we have tested and used this infrastructure internally this is still an experimental service, use it at your own risk.
