Is There a Free eSignature API?
Yes. eSignature API includes a free plan with 50 documents per month, no watermark, no credit card required, and no time limit. Documents on the free plan are fully legally binding in production — not a sandbox or test environment.
What the free plan includes
- 50 documents per month (reset monthly)
- Draw, type, or upload signatures
- Five recipient roles: signer, approver, viewer, form filler, carbon copy
- Ten field types including signature, initials, date, text, and checkbox
- Sequential and parallel signing
- Webhooks on signing completion
- REST API access
- Zapier, Make, HubSpot, Bubble, n8n integrations
- ESIGN Act, UETA, and eIDAS (SES) compliant
- SOC 2 Type II and HIPAA certified infrastructure
- PDF generation from templates included
How eSignature API’s free plan compares
Most other eSignature API providers offer a sandbox or test mode rather than a true free plan:
- Docusign: sandbox only, not for legally binding production documents
- Dropbox Sign: test mode only, not legally binding
- BoldSign: sandbox only, documents watermarked and deleted after 14 days
- PandaDoc: 60 documents per year (5/month) with a 2-recipient cap
- SignNow: 250 sandbox invites, not legally binding
eSignature API’s free plan produces real, production-quality signed documents with no restrictions on use — the only limit is 50 documents per month.
When you outgrow the free plan
Paid plans start at $29/month (1,200 credits). Each signed document costs 10 credits. See full pricing at /pricing/.
