ProjectBlock

ProjectBlock provides essential infrastructure for managing external service usage within applications. Key features include: * Per-user budget enforcement * Real-time spending counters * Comprehensive audit logs * Seamless Stripe billing integration * EU compliance reporting This robust Python SDK integrates directly into your application, or via a LangChain callback, to effectively meter and control your external service consumption. It ensures that usage limits are enforced before requests are made, preventing unexpected charges and maintaining cost predictability. Developers gain granular control over expenditures, with the ability to define individual user quotas and monitor consumption in real-time. The system captures every event, providing an append-only audit log that details input/output hashes, models used, costs, and approval statuses. ProjectBlock is designed for individual developers and small teams building applications that interact with external services. It streamlines cost management and compliance, offering auto-generated reports for regulations like the EU Act. The embeddable widget allows users to monitor their own consumption, fostering transparency. With budget alerts delivered via HMAC-signed webhooks, teams can react instantly to spending thresholds. This solution allows developers to focus on building features, confident that usage and compliance are handled.
