APIbase MCP server

Lets your AI look up flights, prediction markets, crypto prices and weather, paying a small fee per request.

APIbase is a single connection that gives your AI helper access to a big library of outside services, like travel search, prediction markets, crypto data and weather. You do not sign up or get a key first. You pay a tiny amount in digital dollars each time your AI actually uses one of those services. It is handy if you want your AI to answer real-world questions without setting up ten different accounts.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you using what it already knows. An MCP server is a small helper program that gives your AI a new skill or a connection to an outside service. This one connects your AI to APIbase, which is a hub that talks to hundreds of other services for it. So when you ask about a flight or a market price, your AI asks APIbase, and APIbase fetches the answer.

What this MCP server does

You ask your AI a question that needs live outside information, like a flight between two cities or the odds on a prediction market. Your AI sends that request to this helper, APIbase. APIbase picks the right service from its catalog, calls it, and pays the small per-call fee in USDC on your behalf. Then it hands the result back to your AI, which turns it into a normal answer in your chat. You never have to visit each provider's website yourself.

Flow diagram: you ask your AI “Find me flights from London to Lisbon next Friday”, the APIbase MCP server reaches Flights, Prediction markets, Crypto prices and Weather, and you get back A normal answer in your chat.

What it gives back to you

Before you start

What you need

A wallet with a small amount of USDC on Base to pay per call (the README says no signup or API key is needed to start)
An AI app that supports MCP servers, like the Claude desktop app, Cursor or Windsurf

Good to know

Each call costs a small amount of USDC from your wallet, so costs add up if you or your AI make many requests.
