Orbis API Marketplace

orbisapi/orbis-sdk

This gives Claude autonomous access to over 3,000 APIs through the Orbis marketplace, handling discovery, subscription, and execution in one go. It uses a pay-per-call model with x402 USDC on Base, so you're paying for actual usage rather than monthly subscriptions. Reach for this when you need Claude to integrate with external services on the fly without manual API key management or when prototyping integrations where you don't want to commit to full subscriptions yet. The streamable HTTP and SSE transports mean it works with both request-response and real-time data patterns. Think of it as giving Claude a credit card and API directory so it can wire up integrations as needed during a conversation.
