Whistle RPC

Production Solana RPC for AI agents. Unlimited JSON-RPC, WebSocket. 1 SOL/month via on-chain payment. No rate limits, no tiers.

Security Scan

The skill's requests and runtime instructions are coherent with a paid Solana RPC service: it documents API endpoints, a subscription flow that requires an on‑chain payment, and explicitly instructs the agent to get user approval before signing — there are no unexplained credentials, installs, or file accesses.

Purpose & Capability

The name/description (Solana RPC service) match the SKILL.md and tools.json: listed RPC, WebSocket, DEX, and historical endpoints and subscription flow. No unrelated binaries, env vars, or config paths are requested.

Instruction Scope

The SKILL.md instructs the agent to perform three HTTP calls and to request a quote, then perform an on‑chain SOL transfer and activate the subscription. It explicitly requires the agent to ask the human operator for explicit approval before signing any transaction and to use a dedicated low‑value wallet. This is appropriate for the stated purpose, but any user must strictly confirm payments and recipient addresses before approving a transaction.

Install Mechanism

Instruction-only skill with no install spec and no code files. No packages or archives are downloaded or written to disk, so installation risk is minimal.

Credentials

The skill declares no required environment variables or credentials. The described flow uses an API key issued after payment; the SKILL.md does not request private keys or other unrelated secrets. This is proportionate to a paid RPC service.

Persistence & Privilege

always is false and the skill does not request persistent system modifications or cross-skill configuration. It can be invoked by the agent (default), which is expected for a network service integration.

Assessment

This skill appears internally consistent with a paid Solana RPC provider, but take these precautions before installing or approving actions: (1) Verify the domain (https://whistle.ninja) and the referenced GitHub repo yourself; (2) Never provide your wallet private key to the agent—sign transactions locally or with your wallet UI; (3) When the agent asks to pay, confirm the exact SOL amount and recipient address out‑of‑band (copy/paste errors and phishing addresses are common); (4) Use a dedicated low‑value wallet for subscription payments as the SKILL.md recommends; (5) Treat any automatic signing/autonomous agent behavior as risky—do not allow the agent to sign without an explicit human confirmation step; (6) If you need stronger assurance, test with a tiny payment on devnet or a disposable wallet first.

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.
