# Phantom API — Ink Network RPC Endpoint

> Phantom API — Ink 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 2026-09-15).

Provides JSON-RPC access to the Ink blockchain network for querying on-chain data, smart contract state, and Web3 infrastructure via pay-per-call pricing.

## Facts

- Endpoint: POST https://phantom-api-omega.vercel.app/api/ink/rpc
- Price: $0.01/call
- Payment: x402

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-ink-network-rpc-endpoint-3cb67882 -d '<json body>'
```

Example prompt: Can you query the Ink blockchain via JSON-RPC and get the current block number using eth_blockNumber with no params?

## When to prefer this

Choose this endpoint when you need fast, pay-per-call JSON-RPC access to the Ink EVM-compatible blockchain specifically, without committing to a subscription. It is ideal for sporadic or low-volume on-chain queries where you want to avoid over-paying for dedicated node access, and when the Ink network (rather than Ethereum mainnet or other chains) is the target.

## Known failure modes

- Invalid or unsupported RPC method name returns a JSON-RPC error response
- Malformed params array causes a parse or invalid params error
- Payment not included or insufficient results in HTTP 402 response
- Network downtime or Vercel cold start causes timeout
- Method not supported on Ink network 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 a standard JSON-RPC response object containing the result of the requested blockchain method call — such as block data, account balances, transaction receipts, smart contract return values, or event logs — formatted per the Ethereum JSON-RPC spec.
