# Phantom API — Degen RPC Endpoint

> Phantom API — Degen 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 2026-10-10).

Provides pay-per-call JSON-RPC access to blockchain data and smart contract state across 57+ networks via x402 micropayments

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-degen-rpc-endpoint-d15da5ed -d '<json body>'
```

Example prompt: Can you call eth_getBalance with params ['0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045', 'latest'] on Ethereum to check that wallet's current ETH balance?

## When to prefer this

Choose this endpoint when you need low-latency, pay-per-call JSON-RPC access to on-chain data across many EVM-compatible networks without provisioning your own node or committing to a subscription. Ideal for agents making sporadic blockchain queries across multiple chains at $0.01 per call, especially when you want the x402 micropayment flow for trustless, programmatic access.

## Known failure modes

- Invalid or unsupported RPC method name returns a JSON-RPC error object
- Malformed params array causes a parse or invalid params error
- Unsupported network/chain not among the 57+ covered returns an error
- Payment not attached or insufficient USDC causes HTTP 402 Payment Required
- Rate limiting or node downtime returns 503 or timeout
- Contract call reverts on-chain returns execution revert error in 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

A JSON-RPC response object containing the 'result' field with the requested blockchain data (balance in wei, block object, contract return value, transaction receipt, logs, etc.) or an 'error' object if the call failed.
