# QuickNode JSON-RPC Proxy — Hedera Testnet

> QuickNode JSON-RPC Proxy — Hedera Testnet 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 Hedera testnet blockchain node via QuickNode's infrastructure

## Facts

- Endpoint: POST https://x402.quicknode.com/hedera-testnet/
- Price: $10/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/quicknode-bc52bb84
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_QPTIO4oUb0gfntwgSxXJf

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-bc52bb84 -d '<json body>'
```

Example prompt: Call the Hedera testnet via QuickNode JSON-RPC and get the current block number — use method 'eth_blockNumber' with no params and request id 1.

## When to prefer this

Use this endpoint when you need to interact with the Hedera testnet specifically — ideal for testing Hedera-based smart contracts, querying test account balances, or validating transactions before deploying to Hedera mainnet. Prefer this over other QuickNode endpoints when your target chain is Hedera and you are in a development or testing context.

## Known failure modes

- Invalid JSON-RPC method name returns error code -32601 method not found
- Malformed params array causes -32602 invalid params error
- Payment not provided or insufficient results in 402 Payment Required response
- Network congestion or node downtime causes timeout or 503 error
- Using mainnet contract addresses on testnet returns empty or null results
