Whistle RPC — Solana Infrastructure for AI Agents

Production Solana RPC with unlimited JSON-RPC, WebSocket, DEX data, and historical APIs. Designed for AI agents that need reliable blockchain access.

Services

Query param:  https://rpc.whistle.ninja?api_key=YOUR_KEY
Header:       X-API-Key: YOUR_KEY
Header:       Authorization: Bearer YOUR_KEY

Supported RPC Methods

All standard Solana JSON-RPC 2.0:

Account: getBalance, getAccountInfo, getMultipleAccounts, getTokenAccountsByOwner, getMinimumBalanceForRentExemption

Block: getSlot, getBlockHeight, getBlock, getEpochInfo, getRecentPerformanceSamples

Transaction: sendTransaction, simulateTransaction, getTransaction, getSignaturesForAddress, getLatestBlockhash

Node: getHealth, getVersion

WebSocket Subscriptions

slotSubscribe, accountSubscribe, programSubscribe, signatureSubscribe, logsSubscribe

Example:

{"jsonrpc": "2.0", "id": 1, "method": "slotSubscribe"}

Subscription Flow (REST API)

Subscription costs 1 SOL/month, paid on-chain. The flow is three HTTP calls and one Solana transfer.

Important: The payment step sends real SOL on mainnet. The agent must ask the human operator for explicit approval before signing any transaction, display the exact amount and recipient, and use a dedicated low-value wallet.

1. Request a quote

POST https://api.whistle.ninja/api/agent/subscribe
Content-Type: application/json

{ "walletAddress": "YOUR_WALLET_PUBKEY" }

Response: { "nonce": "...", "amount": 1, "recipient": "...", "duration": 30 }

2. Send payment on-chain

Transfer amount SOL (from the quote) to the recipient address using a standard Solana SystemProgram.transfer. The agent must confirm the amount and recipient with the user before signing.

3. Activate the subscription

POST https://api.whistle.ninja/api/agent/activate
Content-Type: application/json

{
  "nonce": "FROM_STEP_1",
  "txSignature": "YOUR_TX_SIG",
  "walletAddress": "YOUR_WALLET_PUBKEY"
}

Response: { "apiKey": "...", "expiresAt": "...", "rpcUrl": "...", "wsUrl": "..." }

Check status

GET https://api.whistle.ninja/api/agent/status/YOUR_API_KEY

Response: { "active": true, "daysLeft": 29, "renewalNeeded": false }

Renewal

When renewalNeeded is true, repeat the subscribe → pay → activate flow. Always confirm with the user before renewing.

Pricing

1 SOL/month. Everything included. No tiers. No rate limits. Revenue is distributed to WHISTLE stakers and node operators.
