# QuickNode JSON-RPC Proxy — Story Mainnet

> QuickNode JSON-RPC Proxy — Story Mainnet is a paid API for AI agents from x402.quicknode.com, paid per call via x402, $10/call, status unknown (last checked 2026-09-15).

Proxies JSON-RPC calls to the Story Protocol mainnet blockchain node via QuickNode infrastructure

## Facts

- Endpoint: POST https://x402.quicknode.com/story-mainnet/
- Price: $10/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/quicknode-f67736ab
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_zMhx7cS9t9z4ElTaM7Pcx

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-f67736ab -d '<json body>'
```

Example prompt: Call eth_getBlockByNumber with params ['latest', true] on the Story Protocol mainnet to get the most recent block and its full transaction details.

## When to prefer this

Use this endpoint when you need to interact with the Story Protocol mainnet blockchain specifically — querying on-chain IP asset data, smart contract state, transactions, or account balances. Prefer this over generic Ethereum endpoints when the target contracts or data live on the Story network.

## Known failure modes

- Invalid JSON-RPC method name returns error code -32601 (Method not found)
- Malformed params array returns error code -32602 (Invalid params)
- Payment not provided or insufficient returns HTTP 402
- Network congestion may cause timeout on heavy eth_call operations
- Unsupported method for Story mainnet returns method-not-supported error

## How this service works

JSON-RPC proxy — story-mainnet

## Output

Returns a standard JSON-RPC 2.0 response object containing the result of the requested blockchain method call — such as block data, transaction receipts, account balances, or contract return values — or an error object if the call failed.
