# QuickNode JSON-RPC Proxy — Lens Testnet

> QuickNode JSON-RPC Proxy — Lens 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 Lens Protocol testnet blockchain, enabling agents to query chain state, submit transactions, and interact with smart contracts on Lens testnet.

## Facts

- Endpoint: POST https://x402.quicknode.com/lens-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-b5ed6ea9
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_mX1YWSnW8zoHsouOFiYF_

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-b5ed6ea9 -d '<json body>'
```

Example prompt: Can you call eth_blockNumber on the Lens testnet via QuickNode to get the latest block height?

## When to prefer this

Choose this endpoint when you need to interact specifically with the Lens Protocol testnet (lens-testnet) chain via standard Ethereum JSON-RPC calls. Prefer this over mainnet endpoints when testing dApps or smart contracts on Lens before production deployment, or when you need a reliable, paid QuickNode-quality RPC node for Lens testnet without managing your own infrastructure.

## Known failure modes

- Invalid JSON-RPC method name returns error code -32601 (method not found)
- Malformed params array returns error code -32602 (invalid params)
- Network or node unavailability returns HTTP 503 or JSON-RPC internal error -32603
- Insufficient payment or expired x402 token returns HTTP 402 Payment Required
- Testnet node sync lag may cause stale or missing data for very recent blocks

## How this service works

## Output

Returns a standard JSON-RPC 2.0 response object containing the result of the requested method (e.g. block number, transaction data, contract return value, account balance) or an error object if the call fails. The response includes the matching request ID and jsonrpc version field.
