# Phantom API — Mantle Network RPC

> Phantom API — Mantle Network RPC 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 2026-10-12).

Provides pay-per-call JSON-RPC access to the Mantle blockchain network for querying on-chain data and interacting with smart contracts

## Facts

- Endpoint: POST https://phantom-api-omega.vercel.app/api/mantle/rpc?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-12
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/phantom-api-mantle-network-rpc-3a36dd2d
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ug-B9mJzBBRFFVFOy0U_8

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-mantle-network-rpc-3a36dd2d -d '<json body>'
```

Example prompt: Can you check the current ETH balance of wallet address 0xAbC...123 on the Mantle network using eth_getBalance?

## When to prefer this

Choose this endpoint when you need pay-per-call access to Mantle network blockchain data without committing to a subscription RPC provider. Ideal for low-frequency queries, agent workflows that need on-chain Mantle data on demand, or when you want micropayment-based access via x402 rather than API key management.

## Known failure modes

- Invalid JSON-RPC method name returns error response
- Malformed params array causes RPC error
- Payment failure (x402) blocks the request
- Contract address not found on Mantle returns null result
- Rate limiting or network congestion causes timeout
- Unsupported Mantle-specific method returns method-not-found error

## 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 standard JSON-RPC response objects containing Mantle blockchain data such as block details, account balances, transaction receipts, smart contract return values, gas estimates, or event logs depending on the method called.
