41 crypto micropayment services via x402 protocol
Overview
A paid micropayment MCP server giving an assistant 63 crypto, market, satellite, IoT and AI data services billed per call in USDC credits.
- What you can do
- Query crypto trading data: gas prices, token prices and metadata, sentiment, whale alerts, DEX liquidity, trade signals, arbitrage, correlations and risk metrics across several chains, plus stock and forex sentiment and Polymarket and Kalshi prediction market odds and search. Inspect wallets and transactions: multi-chain balances, unsigned transaction building, token approvals, bridge quotes, portfolio tracking and optimization, contract security scans and wallet risk scores. Pull satellite and earth observation data: NASA and ESA fire alerts, weather imagery, vegetation health, flood detection, air quality, land use, precipitation, sea surface temperature, soil moisture and ocean color. Use
- When to use it
- Worth adding when an assistant needs on-demand crypto market intelligence, prediction market odds, satellite or earth observation data, IoT sensor readings or pay-per-call AI inference, and you are willing to pay per request. Less suitable if you need free, unlimited or offline data.
- Requirements
- Runs locally as a Python package installed with pip and launched as a module, configured in the desktop client. Needs a Coinrailz API key in the COINRAILZ_API_KEY environment variable, bought as prepaid credits by card or USDC; an optional base URL override variable exists. Network access to the Coinrailz service is required.
Installation
In SourceWeft
- Open Coinrailz in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.
