Issue verifiable certificates with one API call.

Stann is a developer-first API for certificates and digital badges. Send a recipient and a template; get back a PDF, a PNG, a hosted verification page, and a QR code — each credential backed by an Open Badges 2.0 assertion. Built for course creators and online communities.

Everything a credential needs — handled

Issuance, verification, QR, standards, and revocation in one API. You ship the cert; Stann does the plumbing.

One-call issuance

POST a recipient and a template; get back the PDF, PNG, verify URL, and QR in a single response. No multi-step orchestration.

Hosted verification page

Every certificate gets a public page showing Valid / Revoked, the issuer, and the credential — the proof your recipients can share.

QR codes built in

Each credential embeds a QR that resolves to its verification page, so a printed or shared certificate is verifiable in one scan.

Open Badges 2.0

Every credential exposes a standards-compliant hosted assertion, so badges interoperate with the wider Open Badges ecosystem.

Revocation

Revoke a credential via the API; the verification page and assertion reflect it instantly. Trust you can take back.

Bulk from a CSV

Issue a whole cohort at once from a member-list export — drop in a Skool or Circle CSV and every row becomes a verifiable certificate.

How it works

From an API call to a shareable, verifiable credential in three steps.

Call the API

Send a recipient, a template id, and your fields to POST /v1/credentials — or upload a CSV for a whole cohort.

Get a credential

Stann renders the certificate and returns the PDF, PNG, hosted verify URL, and QR code, ready to email or display.

Anyone verifies

Recipients and employers confirm authenticity on the public verification page — no account, no login.

Simple, usage-based pricing

Billed per certificate issued each month. Start free; upgrade when a cohort outgrows it.
