Shared billing hub — no Stripe keys on your side

If you're on Cloudflare Workers, one service binding gives you checkout, a shared credit ledger, and refund-with-feedback. Customers pay once through the hub; refunds return credits with structured feedback you can act on.

1 · Add the service binding

In your wrangler.json, add the portfolio billing service:

"services": [{ "binding":
  "PORTFOLIO_BILLING_SERVICE",
  "service": "riskfreetrial" }]

2 · Create checkout sessions

When a user wants to buy credits for your product, create a checkout session:

await env.PORTFOLIO_BILLING_SERVICE
  .createCheckout({
    domain: "yourproduct.com",
    offeringId: "starter_3",
    email: user.email,
    successUrl: "…/success",
    cancelUrl: "…/pricing"
  })

3 · Consume credits on value

When your product delivers value, consume from the shared balance:

await env.PORTFOLIO_BILLING_SERVICE
  .consumeCredits({
    email: user.email,
    domain: "yourproduct.com",
    deltaCredits: -1,
    actionType: "ai_generation"
  })

4 · Refunds & feedback

When a customer requests a refund through our portal, credits are returned and you get the feedback via the API:

GET /api/refund/requests
  ?domain=yourproduct.com
Authorization: Bearer
  YOUR_PORTFOLIO_BILLING_API_KEY

NEW · MODEL CONTEXT PROTOCOL

Connect refund intelligence to your AI agent

Your refund data shouldn't live in a dashboard your agent can't see. The RiskFreeTrial MCP server pipes refund intelligence — clustered causes, refund rates, prioritized fixes — straight into OpenClaw, Claude, or any MCP-compatible app or agent loop, so your agent can watch refund reasons and draft fixes as part of its normal work.

Add the server to your agent

Streamable HTTP transport — one URL, no install:

{
  "mcpServers": {
    "riskfreetrial": {
      "type": "http",
      "url": "https://www.riskfreetrial.org/mcp"
    }
  }
}

Tools your agent gets

get_refund_intelligence — the clustered refund-cause report, refund rate, confidence, and recommended fixes.
get_merchant_status — connection, policy, and Automation Credits.

Unauthenticated calls compute over the labeled sample dataset with the real engine. Add Authorization: Bearer <merchant token> for your own connected Stripe data.

What agents do with it

Pull the report each cycle, watch a refund cause trend, draft the trial-ending email when "unexpected renewal" spikes, or open an issue when "bug or poor output" crosses a threshold — all inside your existing loop, with your approval gates.

NEW · AD-SUPPORTED FREE TRIALS

Let a sponsor pay for the user's first yes

Some users will never enter a card for a product they haven't tried — and "free tier forever" trains them to never pay. Ad-supported trials are the third option: the user views one sponsor message on a RiskFreeTrial-branded page, and your Stripe purchase flow surfaces as a free subscription — $0 due today, trial period applied, renewal tracked by Penny so nobody gets surprise-charged.

Your product requests a gate. Your server creates a one-time nonce and sends the user to riskfreetrial.org/ad-gate?product=you.com&nonce=…&return_url=…

The user views one sponsor message on the RiskFreeTrial-branded gate — clearly labeled, time-boxed, no dark patterns.

We mint a single-use grant token and redirect back to your return_url with ?grant=…

Your server verifies and unlocks. Call GET /api/adgate/verify?token=… (one-time consume), then grant the trial — free credits, or a Stripe subscription with a trial period showing $0 due today.

Grant tokens are single-use and expire in 10 minutes. Return addresses are allowlisted per partner. Sponsors never see who the user is — the gate shows a message, not a tracker.
