Monetize Cloudflare Workers with Gasless Crypto Payments — Powered by MoltsPay

You can now integrate crypto payments directly into Cloudflare Workers — supporting both EVM and non-EVM chains — with no gas fees, zero cold starts, and just ~10 lines of code. Built on MoltsPay’s Universal Payment Protocol (UPP), this solution redefines how serverless functions handle payments at scale.

The Missing Payment Layer for Serverless & AI Services

Cloudflare Workers revolutionized backend development: code runs across 300+ global edge locations, sub-millisecond cold starts, and fractions of a cent per request. Millions of developers rely on them to build APIs, AI pipelines, and microservices.

But monetizing these services? Traditional options like Stripe left developers stuck with high fees: 2.9% + 30¢ per transaction. For a $0.01 API call, that’s a staggering 3,000% fee. For AI agents — the fastest-growing API users — the pain was even greater: agents lack credit cards, can’t fill out checkout forms, and require programmable, machine-to-machine payment systems.

MoltsPay & the Universal Payment Protocol (UPP)

MoltsPay is building the foundational payment infrastructure for agentic commerce, and we’re setting a new standard for the industry.

At its core lies UPP (Universal Payment Protocol), an open standard created by MoltsPay designed for gasless, instant, machine-to-machine crypto payments. What makes UPP stand out:

• Chain-Agnostic: Works seamlessly across EVM-compatible chains (Base, Polygon) and non-EVM chains like Solana. One protocol, all major chains.
• Zero Gas Costs: Both payers and recipients avoid gas fees — no cross-chain bridges, no gas token management required.
• Agent-Native: Built from the ground up to enable AI agents to discover, pay for, and consume services autonomously.
• Open by Design: A universal standard for any service, chain, or agent — think of UPP as the HTTP of payments.

While others are still debating AI agent payment solutions, MoltsPay has already delivered a production-ready answer.

What @moltspay/cloudflare-plugin Does

The @moltspay/cloudflare-plugin brings UPP’s power to every Cloudflare Worker. Install a single package, and your Worker transforms into a monetizable, agent-accessible service endpoint.

Once deployed, your Worker automatically:

1. Serves a machine-readable service catalog at /.well-known/agent-services.json (the MoltsPay standard for agent service discovery)
2. Returns a 402 Payment Required status for unpaid requests
3. Verifies UPP payments via the MoltsPay API — no private keys stored in your Worker
4. Executes your custom logic only after payment is successfully confirmed

The Payment Flow Simplified

Your Worker never interacts directly with the blockchain. No private keys, no gas management — MoltsPay handles all the underlying infrastructure.

Why This Changes Everything

1. One Protocol, Infinite Chains

Most crypto payment tools lock you into a single chain. UPP breaks that barrier. Whether your users pay with USDC on Base, Polygon, or Solana — the integration process, X-Payment header, and verification flow are identical. MoltsPay abstracts chain complexity, so you can focus on building. As new chains launch, UPP extends to support them — build once, accept payments globally.

2. Viable Micropayments for the First Time

Traditional payment processors can’t handle $0.01 transactions — fees alone exceed the payment amount. With UPP’s zero-fee model, you can profitably charge $0.001 per API call. This unlocks entirely new business models: pay-per-query AI services, per-page translation, per-token inference pricing, and more. MoltsPay makes the long tail of API monetization economically feasible for the first time.

3. AI Agents Are the New Target Audience

The agentic economy isn’t coming — it’s here. AI agents browse, research, code, and make decisions independently, but they’ve been limited to read-only operations due to the lack of agent-focused payment infrastructure. MoltsPay built UPP specifically for this moment.

The /.well-known/agent-services.json standard lets any AI agent:

• Discover your service and its pricing
• Pay via gasless UPP transactions
• Access and use the service’s output

All without human intervention, across any supported chain.

We didn’t adapt human payment rails for agents — we built agent-native payment systems from scratch.

4. Global Reach, Borderless Payments

Traditional payments struggle across borders: varying currencies, complex currency conversion, settlement delays, and local regulatory burdens create major headaches for developers.

Serving users in Tokyo, São Paulo, or anywhere else means navigating regional payment processors, compliance costs, and currency exchange — all adding friction and expense.

With crypto (especially stablecoins like USDC), these complexities vanish. Payments use a single global currency, no exchange rate risks, no fragmented infrastructure.

Paired with Cloudflare’s global network, your service can accept payments from anywhere in the world with a consistent, borderless experience.

The Big Picture: MoltsPay Is Building the Future of Commerce

We believe the future of commerce is agentic — AI agents discovering, evaluating, and paying for services at machine speed. This future relies on three pillars:

1. Discovery: Machine-readable service catalogs (/.well-known/agent-services.json)
2. Payments: Gasless, chain-agnostic, instant crypto (UPP by MoltsPay)
3. Execution: Fast, low-cost, globally distributed compute (Cloudflare Workers)

@moltspay/cloudflare-plugin is where these three pillars converge. It’s the simplest way to turn any Cloudflare Worker into a paid, agent-accessible service — powered by the protocol MoltsPay built exclusively for this vision.

We’re not waiting for the agentic economy. We’re building its payment infrastructure, and leading the industry every step of the way.
