Three keys.
Thirty seconds.
Same surface whether your IDE is your hands or your agent. Sign in, activate sandbox, build — no merchant application required.
OTP sign-in · any email · MCP-ready
Agents have keys too.
MCP. CLI. Typed errors. llms.txt. Plug your agent in the way you'd onboard an engineer — a key and a docs URL.
MCP server
Native tool calling
Drop-in MCP server for Claude Desktop, Cursor, Claude Code. Eleven tools cover the full lifecycle — sessions, payment intents, refunds, tokens, error diagnosis.
CLI
Agent-aware terminal
`--json` everywhere. `doctor --for-llm` outputs markdown diagnostics agents paste straight into context. Webhook tail, signature verify, session create — one command each.
Self-orientation
llms.txt + .well-known
The whole API as a single file an agent can fetch and read. Discovery endpoint returns SDK packages and version pins — no guessing what to install.
Three keys, one click.
Activating sandbox provisions a dedicated test merchant under your account, mints all three credentials, and wires a mock gateway so you can create routable checkout sessions immediately.
Server-only
vp_sk_test_…
Secret API key
Authenticates your server to the Checkout API. Doubles as your webhook signing secret. Never ship to a browser bundle.
Client-safe
vp_pk_test_…
Publishable key
Safe to embed in your storefront or admin UI for read-only surfaces. Mode-prefixed so test traffic never collides with live data.
Return-URL guard
ss_test_…
Session signing secret
Verifies the signature on the return URL after a buyer completes checkout. Prevents tampered redirects from spoofing payment success.
From zero to test charge.
01
Sign in
OTP code to your inbox or Google sign-in. Any email works for sandbox — no business required.
02
Activate Vora Sandbox
One button on /dashboard/developers. Three keys appear, copy each one, store in your secrets manager.
03
Drop into a sample
Clone a sample app, paste the keys into .env, run npm install + dev. Live test charge in under five minutes.
What you can build against.
Two integration paths. Two server SDKs. Signed webhooks for every state change. All production-live.
Hosted Checkout
Redirect to a URL.
A fully hosted checkout you reach by URL. Create a session, redirect the buyer, handle the signed return. Two endpoints, one webhook.
Embedded fields
Card on your page.
Drop card, address, and wallet fields into your own checkout. PCI scope on us — the buyer's card never touches your server or your DOM.
Webhooks
Signed. Retried. Replayable.
HMAC-SHA256-signed events for every state change. Exponential backoff retries. Tail them live in your terminal with the CLI.
Server SDKs
Node + Python.
Typed clients on npm and PyPI. Idempotency keys, automatic retries, error-help envelopes, signed-webhook verifiers — same surface in both.
Sample apps
Clone-to-charge in five.
Express, Flask, Next.js, pay-by-link, frame-react. Clone, paste keys, run dev. A live test charge in under five minutes.
Sandbox
Real flows. No real money.
A dedicated test merchant per developer, mock gateway wired in. Test cards for success, decline, 3DS. Same API contract as production.
Spec, samples, support.

Click through what you'll be coding
Embedded fields, hosted checkout, agentic dev — interactive demos powered by scripted state. Use them to map the integration before you write any code.
Embedded payment form
Tokenized card fields rendered inline on your own page. Full UI control, the buyer never leaves your domain, and your PCI scope stays at SAQ-A.
Ideal for
SaaS apps · custom checkouts · CRM platforms
VORA hosted checkout
Redirect the buyer to a VORA-hosted payment page; we tokenize the card and return a signed result to your server. Lowest PCI scope, fastest integration path — ship in days, not months.
Ideal for
E-commerce stores · marketplaces · platforms
Agentic-powered development
Vera doesn't just answer questions — she generates API keys, provisions sandboxes, and walks a developer to their first live transaction with real tool-calls and inline code snippets.
Ideal for
Developers integrating · technical evaluators
Build first. Apply later.
Sandbox keys mint instantly. The merchant application waits until you're ready to ship — not the other way around.
