Starter: 100 calls/month. Pro (€9/mo): 10,000/month. Business (€29/mo): 50,000/month. Pro and Business can opt into metered overage from the dashboard — we warn at 80 % and 100 % before any charge.
Node.js (npm: toolcenter), Python (PyPI: toolcenter), PHP (Packagist: toolcenter/sdk). Go SDK is on the roadmap — use raw HTTP in the meantime. Browse SDKs.
