Signbee is an API-based e-signature service that signs documents with a single POST /api/v1/send call, handling the entire signing flow between sender and recipient and returning the final signed PDF with a tamper-proof SHA-256 certificate, timestamps, and IP addresses. It can create PDFs from Markdown (including tables) or sign existing PDFs via a pdf_url, supports zero-configuration setup, and optionally delivers real-time signing webhooks on the Pro/Business plans. It offers Free, Pro, and Business pricing with increasing document quotas and features, including email delivery to both parties and optional webhook support, enabling AI agents to perform signing with minimal integration.
