# Phantom API — Boba Network RPC Endpoint

> Phantom API — Boba Network 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 2026-10-16).

Provides JSON-RPC access to the Boba Network blockchain, enabling queries for on-chain data, smart contract state, and transaction information on the Boba L2 network.

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 phantom-api-boba-network-rpc-endpoint-25401529 -d '<json body>'
```

Example prompt: Can you check the current BOBA token balance for wallet address 0xABC123... on the Boba Network using an eth_call to the token contract?

## When to prefer this

Choose this endpoint when you specifically need to query Boba Network (an Ethereum L2 optimistic rollup) on-chain data via standard JSON-RPC. It is pay-per-call at $0.01 USDC with no subscription required, making it ideal for sporadic or agent-driven queries. Prefer this over self-hosted nodes when you want zero infrastructure overhead for Boba Network access.

## Known failure modes

- Invalid RPC method name returns a JSON-RPC error with code -32601
- Malformed params array causes a -32602 invalid params error
- Querying a non-existent block or transaction returns null result
- Network congestion or node unavailability may cause timeout errors
- Payment failure via x402 results in 402 Payment Required before the call is processed

## 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

Returns a standard JSON-RPC response object containing the result field with blockchain data such as balances (in hex wei), block objects, transaction receipts, contract return values, or error objects if the call fails.
