Templates

Generate the document you'll send.

Store a template once with {{placeholders}}, then send only the data that changes. We render a pixel-perfect PDF, hash it with SHA-256, and attach it to the envelope.

FAQ

Questions, answered.

What is Signed?

Signed is a developer-first e-signature API that also generates the document for you. With one API call you generate a document from a template or HTML, send it to one or more signers, collect a legally binding electronic signature, and get back the sealed PDF plus a court-grade audit trail.

How much does Signed cost?

Signed is $0.15 per envelope with document generation included, and volume bundles lower the rate. Test mode is free and unlimited, with no per-seat pricing and no sales call.

Are signatures created with Signed legally binding?

Yes. Signed implements Simple Electronic Signatures (SES) under US ESIGN and UETA and EU eIDAS. Every envelope captures consent and intent, authenticates the signer, and ships with a tamper-evident, hash-chained audit trail sealed with a PAdES signature, plus an RFC 3161 timestamp when configured.

How is Signed different from DocuSign?

Signed is built for developers: a clean API and SDK you embed in your own product, transparent $0.15-per-envelope pricing with no envelope caps, and document generation built in. DocuSign is enterprise-sales-gated with per-seat pricing and was not designed for embedding.

Which countries does Signed support?

Signed supports the United States and the European Union — covering ESIGN and UETA in the US and eIDAS SES in the EU.

Does Signed generate the document too?

Yes. Send a stored template plus data, raw HTML, or a file URL, and Signed renders a pixel-perfect PDF, hashes it with SHA-256, and attaches it to the envelope — so you never need a separate document-generation vendor.
