seal.club Handbook
Quickstart

seal.club — PDF sealing API documentation

REST API reference, webhook events, and the seal.club customer portal — native SvelteKit handbook at /docs.

Edit on GitHub

seal.club is a hosted service for cryptographic sealing of PDF documents: upload or reference a file, create a sealing job, and verify receipts in your own pipelines. These docs mirror how we expect to narrate the product once OpenAPI specs and typed SDKs ship alongside the dashboard.

They are deliberately mocked (example URLs and payloads) so the handbook stays useful before the final wiring goes live.

Quickstart

Request your first sealing job end-to-end in a sandbox environment.

API overview

Base URLs, versioning, idle timeouts, and how jobs relate to attestations.

Portal

Where teams manage environments, quotas, webhook endpoints, and audit logs.

Platform overview

Two-plane build: thin Vercel control plane vs Cloudflare seal_api.

seal_api design

R2 staging, GCP KMS sign, rfc3161.ai.moda/adobe timestamps, ~300ms inline path.

Handbook maintenance

How to add pages, update navigation, and run docs:check.

What ships today versus what is illustrative

Product marketing at https://seal.club/product summarizes the roadmap. Anything under API nav in here uses consistent naming with that page but uses sample IDs so you never mistake examples for prod traffic.

Support

Use the billing email on your invoice or #sealclub-api if we have shared Slack. Mention your environment id (env_…) plus a correlation id from the Seal-Trace-Id response header—we keep them in logs while jobs move through queues.
