# Phantom API — Sui RPC Endpoint

> Phantom API — Sui 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).

Executes JSON-RPC calls against the Sui blockchain network, returning on-chain data such as objects, transactions, and account state.

## Facts

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-sui-rpc-endpoint-f02a1f16 -d '<json body>'
```

Example prompt: Can you look up the current balance and owned objects for Sui wallet address 0xabc123... using the Sui RPC?

## When to prefer this

Choose this endpoint when you need pay-per-call access to Sui blockchain RPC without managing your own node or committing to a subscription. Ideal for agents that occasionally query Sui chain data across multiple networks and want metered, low-friction access. Prefer this over self-hosted nodes when you need instant setup and are comfortable with per-call USDC micropayments.

## Known failure modes

- Invalid RPC method name returns method-not-found error
- Malformed params array causes invalid-params error
- Non-existent object ID or transaction digest returns null result
- Payment failure via x402 blocks the request before it reaches the RPC node
- Rate limiting or node unavailability returns a server error
- Network congestion may increase latency beyond typical fast response

## 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 JSON-RPC response from the Sui node containing the requested on-chain data — such as object fields, transaction status, coin balances, event logs, or smart contract state — depending on the method invoked.
