# Phantom API – Kaia Network RPC

> Phantom API – Kaia 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 2026-09-14).

Executes JSON-RPC calls against the Kaia (formerly Klaytn) blockchain network, enabling on-chain data queries and smart contract interactions via a pay-per-call endpoint.

## Facts

- Endpoint: POST https://phantom-api-omega.vercel.app/api/kaia/rpc
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/phantom-api-kaia-network-rpc-9bd99b91
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_okzPh4j4LbsyVDgrH_Q8-

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-kaia-network-rpc-9bd99b91 -d '<json body>'
```

Example prompt: Can you check the latest block number and current gas price on the Kaia blockchain using an RPC call?

## When to prefer this

Choose this endpoint when you need direct, low-latency RPC access to the Kaia (formerly Klaytn) blockchain specifically, and want pay-per-call pricing without a subscription. Ideal for agents that need occasional on-demand Kaia chain queries without committing to a dedicated node provider.

## Known failure modes

- Invalid JSON-RPC method name returns error code -32601 (method not found)
- Malformed params array returns error code -32602 (invalid params)
- Network congestion or node unavailability may cause timeouts
- Insufficient x402 payment results in 402 Payment Required response
- Querying non-existent block number or transaction hash returns null result

## 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 the requested on-chain data (block info, balance in hexadecimal, contract return values, transaction receipts, etc.) or an error object with code and message if the call fails.
