# QuickNode JSON-RPC Proxy — Solana Devnet

> QuickNode JSON-RPC Proxy — Solana Devnet is a paid API for AI agents from x402.quicknode.com, paid per call via x402, $10/call, status unknown (last checked 2026-09-14).

Proxies JSON-RPC calls to the Solana devnet blockchain, enabling queries and transactions on the Solana test network via standard JSON-RPC 2.0 protocol.

## Facts

- Endpoint: POST https://x402.quicknode.com/solana-devnet/
- Price: $10/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability quicknode-edee0cbe -d '<json body>'
```

Example prompt: Call getBalance on Solana devnet for the account address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU and tell me the current lamport balance.

## When to prefer this

Use this endpoint when you need to interact specifically with the Solana devnet network for testing, development, or staging purposes — not mainnet. Prefer this over other chains when your target application or smart contract is deployed on Solana devnet. Choose this when you need QuickNode's reliable RPC infrastructure with x402 micropayment access rather than managing your own node.

## Known failure modes

- Invalid JSON-RPC method name returns error code -32601 (method not found)
- Malformed params array returns error code -32602 (invalid params)
- Missing jsonrpc '2.0' field causes request rejection
- Payment not included or insufficient USDC triggers 402 Payment Required
- Devnet node unavailable or congested returns 503 or timeout
- Invalid account address format returns parse error
