# Synapse API — Zora RPC Endpoint

> Synapse API — Zora RPC Endpoint is a paid API for AI agents from synapse-api-brown.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Proxies JSON-RPC calls to the Zora blockchain network via a pay-per-call gateway, enabling on-chain reads and writes on Zora.

## Facts

- Endpoint: POST https://synapse-api-brown.vercel.app/api/zora/rpc
- Price: $0.01/call
- Payment: x402
- Status: unknown

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_892Sy5rfWAWeBjBEPD4gL

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 synapse-api-zora-rpc-endpoint-0e6082dc -d '<json body>'
```

Example prompt: Call eth_getBalance on the Zora network for wallet address 0xAbCd...1234 at the latest block and tell me the balance in ETH.

## When to prefer this

Use this endpoint when you specifically need to interact with the Zora Layer 2 network via standard Ethereum JSON-RPC and want pay-per-call pricing without managing your own RPC node or subscription. Prefer over self-hosted nodes when cost per call at $0.01 USDC is acceptable and you need zero infrastructure overhead.

## Known failure modes

- Invalid RPC method name returns JSON-RPC error -32601
- Malformed params array returns parse error -32700
- Payment failure via x402 returns 402 Payment Required before call is processed
- Network congestion on Zora may cause timeouts
- Unsupported method returns -32004 method not supported
- Transaction submission with invalid nonce returns execution error
