Pro
Stripe billed the subscription. Issue an API key below. We store a hash, not the secret. This key raises request limits on /api/pro/*. It does not grant a 24h SLA, white-label, or on-prem — email support@proofchain.us for those.
Send the key as header X-API-Key. Check it with GET /api/keys/me. If checkout succeeded and this page failed, email support@proofchain.us — we fulfill keys manually too.
