# QuickNode LTC Mainnet JSON-RPC Proxy

> QuickNode LTC Mainnet JSON-RPC Proxy 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 Litecoin mainnet blockchain via QuickNode's infrastructure

## Facts

- Endpoint: POST https://x402.quicknode.com/ltc-mainnet/
- Price: $10/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

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-50b212d1 -d '<json body>'
```

Example prompt: Call the Litecoin mainnet via QuickNode and get the latest block number using getblockcount — I need to confirm the current chain height.

## When to prefer this

Use this endpoint when you need to interact with the Litecoin (LTC) mainnet blockchain via standard JSON-RPC, such as querying balances, fetching blocks, broadcasting transactions, or reading chain state. Prefer this over generic Ethereum-compatible RPC endpoints when your target chain is specifically Litecoin, and prefer QuickNode's infrastructure for reliable, high-uptime node access without running your own node.

## Known failure modes

- Invalid JSON-RPC method name returns an error object with code and message
- Missing or malformed params array causes a parse/invalid params error
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Network or node unavailability returns a 503 or timeout error
- Unsupported method for Litecoin returns method-not-found error

## How this service works

## Output

A JSON-RPC 2.0 response object containing the result of the requested Litecoin blockchain method call, including the result field with the blockchain data (block info, balance, transaction details, etc.), the matching request ID, and any error object if the call failed.
