eSignBase

Pay-As-You-Go E-Signature API for Business Workflows

eSignBase is an e-signature platform for software platforms and businesses that automate document signing. It lets teams send, sign, and track documents through a REST API and a web dashboard, handling customer, contractor, and supplier agreements while keeping signing history and completed documents together on EU-based infrastructure. The service is designed to work within existing workflows rather than as a standalone signing tool.

Integration is handled through OAuth2 and the REST API, with Python and Node.js SDKs available. A visual editor supports reusable document templates that can be populated through the API, and webhooks notify applications when signing is complete. The web dashboard covers document status, template management, and workflows with one or more signers. A sandbox account allows testing the API before production use, and integration support is available for setup questions. A separate free quotation creator produces PDF quotes without an account, with optional signing through paid credits.

Packaging is usage-based: document credits are purchased in tiers, include API usage and unlimited templates, and do not expire. There is no monthly subscription or per-seat fee, and credit purchases are final and non-refundable. A custom agreement option is offered for tailored needs.
