Build billing without building billing.
REST API, webhooks, embeddable checkout, and API key management — everything you need to accept card and crypto payments without spinning up a payment processor.
Why payment infrastructure keeps failing people like you.
Stripe setup is a project by itself.
Webhooks, idempotency keys, refund logic, payout schedules, disputes — implementing payments properly takes weeks. Then you have to maintain it forever.
Crypto-native users churn when they hit a card-only checkout.
A growing share of developer tooling customers holds stablecoins and prefers to pay that way. A card-only checkout is a closed door.
Bank accounts, registered entities, tax IDs — just to get paid.
Traditional payment processors require a full business setup. If you're early-stage or operating across jurisdictions, this is a wall.
From zero to getting paid — in under ten minutes.
Create an API key and configure your webhook endpoint
Generate API keys from the dashboard. Point Vulta at your HTTPS endpoint. We'll sign every payload so you can verify origin and prevent replay attacks.
Embed checkout or create links via API
Drop our checkout widget onto your pricing page with one script tag, or generate payment links programmatically via the REST API for dynamic invoice amounts.
Webhook fires on confirmation — your logic runs
When a payment is detected on-chain, we POST to your endpoint immediately. Provision the account, send a confirmation email, update your database.
The features that matter for your use case.
No bloat. No enterprise pricing for basic functionality. Just the tools that make collecting payment simple.
