What it does
X402 Services exposes 147 onchain, trading, and AI tools for Robinhood Chain (chainId 4663), including RPC endpoints, block/transaction/balance data, token transfers, contract interactions, tokenized-stock registry lookups, USDG statistics, address webhooks, and LLM inference—all paid per call in USDG or USDC with no API keys or signup required.
- Query block data, transaction status, account balances, and gas estimates on Robinhood Chain to track onchain activity and build transactions.
- Monitor token transfers and contract events on Robinhood Chain by registering webhooks that POST updates to your agent instead of polling.
- Call LLM inference (fast or frontier models) directly from your agent, with payments settled in USDG on Robinhood Chain.
Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
