# QuickNode Celestia Mainnet JSON-RPC Proxy

> QuickNode Celestia 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 Celestia mainnet blockchain network via QuickNode's infrastructure

## Facts

- Endpoint: POST https://x402.quicknode.com/celestia-mainnet/
- 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-62a3862d
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap__n7_ffBgcUVgEFqttUQNw

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-62a3862d -d '<json body>'
```

Example prompt: Call the Celestia mainnet node and get me the latest block height — use JSON-RPC 2.0 with method 'header.NetworkHead' and no params.

## When to prefer this

Use this endpoint when you need to interact with the Celestia mainnet blockchain specifically — querying blocks, transactions, blob data, or network state on the live production network. Prefer this over the Celestia Mocha testnet endpoint when working with real mainnet data. Choose this when you need reliable, hosted RPC access to Celestia without running your own node.

## Known failure modes

- Invalid JSON-RPC method name returns error response with code and message
- Malformed params array causes parse or invalid params error
- Network congestion or node unavailability returns 503 or timeout
- Payment failure (402) if USDC payment is not processed correctly
- Unsupported method for Celestia returns method not found error
