# Phantom API — BOB Network RPC Endpoint

> Phantom API — BOB 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 2026-09-14).

Provides JSON-RPC access to the BOB (Build on Bitcoin) blockchain network for querying on-chain data and interacting with smart contracts, paid per-call via x402.

## Facts

- Endpoint: POST https://phantom-api-omega.vercel.app/api/bob/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-bob-network-rpc-endpoint-f4e027df
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_023yo-7u4yzb0PISl3LCe

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-bob-network-rpc-endpoint-f4e027df -d '<json body>'
```

Example prompt: Can you fetch the latest block number on the BOB network using eth_blockNumber — I need to check current chain state?

## When to prefer this

Choose this endpoint when you need pay-per-call, no-subscription JSON-RPC access to the BOB (Build on Bitcoin) network specifically. It is ideal for agents that make infrequent or bursty blockchain queries and want to avoid managing node subscriptions. Prefer it over generic RPC providers when the BOB chain is the target network and micropayment billing via x402/USDC is acceptable.

## Known failure modes

- Invalid RPC method name returns JSON-RPC error with code -32601 (method not found)
- Malformed params array causes parse error (-32700) or invalid params error (-32602)
- Network congestion or node unavailability may cause timeouts
- Calling a write method (eth_sendRawTransaction) without a signed transaction payload will fail
- Payment failure via x402 protocol will block the request before it reaches the RPC node

## 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 blockchain data (block info, balance, contract return value, transaction receipt, etc.) or an error object with code and message if the call fails.
