HTTP RPC API

Overview

OrbitFlare RPC nodes accept HTTP requests using the JSON-RPC 2.0 specification. This API allows you to interact with the Solana blockchain for querying data and submitting transactions.

Request Format

To make a JSON-RPC request, send an HTTP POST request with the following specifications:

Endpoint: https://fra.rpc.orbitflare.com?api_key=YOUR_LICENSE_KEY
Header: Content-Type: application/json
Body: JSON object with these fields:

Field	Type	Description
`jsonrpc`	string	Must be “2.0”
`id`	string/number	Unique request identifier
`method`	string	The RPC method name
`params`	array	Array of method parameters

Example Request

curl https://fra.rpc.orbitflare.com?api_key=YOUR_LICENSE_KEY -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "getBalance",
  "params": [
    "83astBRguLMdt2h5U1Tpdq5tjFoJ6noeGwaY3mDLVcri"
  ]
}'

Response Format

Responses will be JSON objects containing:

Field	Type	Description
`jsonrpc`	string	Always “2.0”
`id`	string/number	Matches request identifier
`result`	varies	The method’s result data
`error`	object	Error details (if applicable)

Commitment

Many methods accept a commitment parameter to specify how confirmed the data should be:

processed: Latest block (fastest, not confirmed)
confirmed: Confirmed by supermajority (balance between speed and finality)
finalized: Finalized by supermajority (slowest, fully confirmed)

Example with commitment:

curl https://fra.rpc.orbitflare.com?api_key=YOUR_LICENSE_KEY -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "getBalance",
  "params": [
    "83astBRguLMdt2h5U1Tpdq5tjFoJ6noeGwaY3mDLVcri",
    {"commitment": "finalized"}
  ]
}'

Batch Requests

You can send multiple requests in a single HTTP call by providing an array of request objects:

curl https://fra.rpc.orbitflare.com?api_key=YOUR_LICENSE_KEY -X POST -H "Content-Type: application/json" -d '[
  {
    "jsonrpc": "2.0",
    "id": 1,
    "method": "getBalance",
    "params": ["83astBRguLMdt2h5U1Tpdq5tjFoJ6noeGwaY3mDLVcri"]
  },
  {
    "jsonrpc": "2.0",
    "id": 2,
    "method": "getBlockHeight",
    "params": []
  }
]'

Common Types

Type	Description
Pubkey	Base-58 encoded public key string
Hash	Base-58 encoded SHA-256 hash string
Signature	Base-58 encoded Ed25519 signature
Slot	Integer block height/slot number

Health Check

You can check node health with a GET request:

curl "https://fra.rpc.orbitflare.com/health?api_key=YOUR_LICENSE_KEY"

Possible responses:

ok: Node is healthy and up-to-date
behind { slots: number }: Node is behind by N slots
error: Node is unhealthy

Rate Limits

Rate limits vary by subscription tier. See the Authentication & Limits page for the exact RPS and TPS values per plan.

Best Practices

Use Appropriate Commitment Levels
- Use processed for UI updates
- Use confirmed for most operations
- Use finalized for critical operations
Optimize Requests
- Use batch requests when possible
- Implement proper caching
- Choose appropriate polling intervals
Handle Errors
- Implement proper error handling
- Use exponential backoff for retries
- Monitor request failures
