# Phantom API — BNB Chain RPC Endpoint

> Phantom API — BNB Chain 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).

Provides pay-per-call JSON-RPC access to the BNB Smart Chain (BSC) blockchain network for querying on-chain data and interacting with smart contracts.

## Facts

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

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_C9eTiYXihJVjsO4iIJJ6G

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-bnb-chain-rpc-endpoint-6a29a626 -d '<json body>'
```

Example prompt: Can you check the current BNB balance for wallet address 0xAbC123... on BNB Smart Chain using eth_getBalance?

## When to prefer this

Choose this endpoint when you need direct, low-latency JSON-RPC access to BNB Smart Chain and want pay-per-call billing in USDC without a subscription. Prefer it over hosted node providers when you need x402 micropayment compatibility or when building agents that make infrequent BSC calls and want to avoid monthly plans.

## Known failure modes

- Invalid RPC method name returns JSON-RPC error with code -32601 (Method not found)
- Malformed params array causes -32602 (Invalid params) error
- Payment not included or insufficient USDC causes HTTP 402 Payment Required
- Network congestion or node unavailability causes timeout or 503 error
- Querying a non-existent block or transaction returns null result field

## 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 an 'id', 'jsonrpc' version string, and a 'result' field with the requested on-chain data (e.g. hex-encoded balance, block object, transaction receipt, contract return value) or an 'error' object with code and message if the call failed.
