# eSignatures.com

> eSignatures.com is the next generation of online signatures: a mobile-first electronic signature platform with a REST API, pay-per-use pricing and no subscription. Contracts are responsive text built from Markdown templates, not PDFs, so they read cleanly on phones and can be read and edited natively by AI tools. Operating since 2017, based in Melbourne, Australia.

Key facts:

- Pricing: transparent and stable. A flat $0.49 per contract, regardless of signer count or page count, with no price hikes. No subscriptions, annual contracts or auto-renewals. No seat fees, envelope caps, overage charges or feature tiers: every feature is included for every customer, and the API, integrations and Contract links cost the same as the dashboard. Credits never expire. Volume discounts available; non-profits get 40% off. Optional SMS delivery and live photo ID verification are the only extras, each at a flat price.
- Legal validity: compliant with most major frameworks, including the US ESIGN Act and UETA, HIPAA, 21 CFR Part 11, EU and UK eIDAS (simple electronic signatures; advanced and qualified are not offered), Canada UECA, Australia and New Zealand ETA, and South Africa ECTA. GDPR-aligned data processing.
- Security: ISO 27001 certified and regularly audited. Choice of data centre: US East, Canada, EU (Frankfurt), UK (London) or Australia (Sydney). HIPAA BAA available.
- Privacy: contract data is never analyzed, mined, profiled or resold. No marketing emails sent to customers or signers, ever.
- Sending: contracts can be sent from the web dashboard, the REST API, Zapier and Make, or any MCP-enabled AI assistant. Contract links publish a single agreement as a reusable link, QR code or embedded form, and every submission becomes its own contract.
- Signing: each signer gets a unique sign page, delivered by email or SMS, or embedded in your own site or app via an iframe (for API-created contracts and Contract links). Optional email or SMS verification codes and live photo ID verification. Each signed contract is delivered as a PDF with a full audit trail; PDF/A available.
- Editing after sending: contract content, placeholder values and signer details can be updated after a contract is sent, without voiding it.
- AI and MCP: eSignatures.com is the only major esign service which has Markdown compatible contracts and templates, so AI assistants can fully drive the platform over MCP. That includes drafting new templates, editing contract and template content (also after sending), filling placeholder and signer fields, sending, and tracking status.
- Languages: 26 signing locales (cz, da, de, el, en, en-GB, es, fi, fr, hr, hu, id, it, ja, nl, no, pl, pt, ro, rs, sk, sl, sv, vi, zh-CN, zh-TW).
- No sales call required. Free test accounts with full functionality; test contracts are free and stamped "demo".

## Developers

- [API reference](https://esignatures.com/docs/api): REST API v1.3. Contracts, signers, placeholder fields, templates, collaborators, webhooks, embedded signing and Extended Markdown syntax
- [MCP server](https://esignatures.com/docs/mcp): Connect Claude, ChatGPT or any MCP-enabled AI assistant to draft, fill and send contracts
- [Extended Markdown](https://esignatures.com/docs/extended_markdown.md): The syntax for writing templates and contracts. Standard Markdown plus a backtick-wrapped JSON config on any line to add Signer fields (text, date, dropdown, checkbox, radio button, file upload), alignment and header counters, and `{{key}}` Placeholder fields. Read this before drafting or editing content via the API or MCP

API essentials:

- Base URL `https://esignatures.com/api/`. JSON over HTTPS. HTTP Basic Auth with the Secret Token as username and an empty password.
- Send a contract with one call: `POST /api/contracts` with `template_id` and `signers`. Pass `"test": "yes"` for free test contracts.
- Use webhooks rather than polling. Events include `contract-sent-to-signer`, `signer-viewed-the-contract`, `signer-signed`, `signer-declined`, `contract-signed` and `contract-withdrawn`. Requests are signed with an `X-Signature-SHA256` HMAC header.
- Templates are written in Markdown. Extended syntax appends a backtick-wrapped JSON config to a line to define Signer fields (text, date, dropdown, checkbox, radio button, file upload) and formatting.
- Placeholder fields (`{{key}}`) can be replaced with text, Markdown or the full content of another template.
- Content updates use `find_markdown` / `replace_with_markdown` edits, with `dry_run` support.
- Embed signing by appending `?embedded=yes` to a signer's `sign_page_url` in an iframe.
