Overview
AI-generated overview
Lets an assistant fetch crypto market data through a pay-per-call x402 API, paying in USDC on Base from a local EVM wallet.
- What it does
- This local MCP server connects an assistant to a crypto market data API that charges per call over x402, settled in USDC on Base. A free catalog and sample tools return data without a wallet, while paid tools require a funded EVM wallet. It runs as a local stdio process, so the assistant starts it on the user's machine.
- When to use it
- Use it when an assistant needs crypto market data and the user is willing to pay small per-call USDC amounts from a dedicated wallet. It is not needed if only free catalog and sample data are wanted.
- Requirements
- Runs locally over stdio, typically via the npm package. Node.js is required. A funded EVM wallet private key is needed for paid tools, supplied as AGENT_PRIVATE_KEY. Optional settings include BLOCKCHAINIQ_BASE_URL, BLOCKCHAINIQ_NETWORK (base or base-sepolia) and MAX_USDC_PER_CALL. Network access is required.
Before you install
Paid tools spend real USDC from the wallet whose private key is set in AGENT_PRIVATE_KEY; the input advises using a dedicated low-balance wallet. MAX_USDC_PER_CALL caps the price per call, and the dearest call is $0.25. Requests on networks other than the configured one are refused. Keep the private key out of shared or logged environments.
