Overview

AI-generated overview

A local MCP server that lets an assistant browse the Orbis API marketplace and call its APIs, paying per call in USDC on Base via x402.

What you can do
Search and list APIs available on the Orbis marketplace across data, AI, finance and utilities categories, with pricing and payment details shown per call. Call any listed API directly, with the x402 USDC micropayment on Base handled by the server. Register an agent wallet for tracking and subscribe to an API for discounted access.
When to use it
Useful when an assistant needs data or services from many third-party APIs without signing up for each provider or managing individual API keys, and when paying a small per-call fee in USDC is acceptable.
Requirements
Runs locally via npx, so Node.js is needed; desktop MCP clients only. A Base mainnet wallet private key is supplied through the WALLET_PRIVATE_KEY environment variable to fund USDC micropayments, and the README also mentions an optional ORBIS_KEY. Network access to the Orbis marketplace and Base is required.
Before you install
The server requires a Base mainnet wallet private key in WALLET_PRIVATE_KEY, which controls real funds; use a dedicated low-balance wallet. Calls spend USDC automatically at roughly one cent each, so costs accumulate without per-call confirmation. Subscribing to an API and registering a wallet change account state. The README and manifest disagree on the credential variable name, so verify configuration before use.

Installation

In SourceWeft

  1. Open Orbis API Marketplace in the dashboard and add it to a workspace.
  2. 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.

How payments work

Orbis uses the x402 protocol — an open HTTP payment standard built on Base. When your agent calls an API:

  1. Orbis returns a 402 Payment Required response with payment details
  2. The MCP server handles the USDC payment on Base automatically
  3. The API call completes — total cost: $0.01

No wallets to configure for browsing. To make paid calls, provide your Base wallet via ORBIS_KEY.
