# Phantom API – Berachain RPC Endpoint

> Phantom API – Berachain RPC Endpoint is a paid API for AI agents from phantom-api-omega.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

## 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 phantom-api-berachain-rpc-endpoint-f4d46283 -d '<json body>'
```

Example prompt: Can you call eth_getBalance on Berachain for wallet address 0xAbC123... at the latest block so I can see the current BERA balance?

## When to prefer this

Choose this endpoint when you specifically need to interact with the Berachain network via standard JSON-RPC and want pay-per-call pricing without a subscription. Prefer it over self-hosted nodes when you need zero infrastructure management, or over other RPC providers when Berachain-specific network support is the priority.

## Known failure modes

- Invalid JSON-RPC method name returns an error response with code -32601
- Malformed params array returns a parse or invalid params error
- Payment not included or insufficient USDC results in HTTP 402 Payment Required
- Berachain node unavailable or syncing may return temporary 503 or timeout
- Calling a non-existent contract address returns 0x or null result silently

## How this service works

Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.

## Output

A standard JSON-RPC response object containing the result field with the requested on-chain data (e.g. balance in wei, block object, transaction receipt, or smart contract return value), or an error object with code and message if the call fails.
