Technical evaluation No credit card for test key No document upload

Evaluate sealing in six clear steps

Create an account, generate a free test API key, and run an end-to-end seal in minutes. This path is designed for developer and product teams validating fit before production rollout.

Process guide

Step-by-step technical eval

Follow this exact sequence to validate API access, local sealing behavior, and Acrobat results before moving to trusted production certificates.

See Pricing

Step 1

Create an account

Create your Trusted Signatures account to access API credentials and evaluation tooling.

Step 2

Create a test API key

Generate a free test key. This enables sealing with an untrusted certificate and requires no credit card.

Step 3

Install CLI or Zap

Choose the integration path that matches your workflow: command line for engineering pipelines or Zapier for automation.

Step 4

Configure with your API key

Follow documentation to set key ID and key secret in your selected toolchain.

Step 5

Seal a document

Run a seal operation using your test key and verify your output PDF is generated without uploading source documents.

Step 6

Open in Acrobat

The document will be sealed but not trusted yet. In this test mode you should not expect the blue badge or green check.

How it works

Seal and verify workflow

Use this model during technical evaluation to validate the sealing path and reader verification behavior end-to-end.

Seal PDF

  1. Send a request using CLI/API/Zap to Trusted Signatures (no document upload).
  2. Embed the returned seal into the PDF.
  3. Distribute the sealed PDF.

Verify PDF

  1. Open the PDF in a reader or use Trusted Signatures Validator.
  2. The seal is verified automatically and the sealer name is displayed.
