Paywall HTTP endpoints
Wrap an HTTP route with requirePayment so an agent must pay before the handler runs. The source says this works with frameworks such as Express, Hono, Next.js, and FastAPI.
Loomal
Loomal adds paywalls to APIs, MCP tools or hosted files, letting AI agents pay per request in USDC on Base with direct settlement.
What Loomal is
Loomal is a payments layer for agentic commerce. It lets developers add a paywall to an API, MCP tool, or hosted file so AI agents can discover the price, pay in USDC, and receive the requested result.
The product is built around x402, the HTTP payment handshake, and settles payments on Base in seconds. The site says this removes API-key juggling and invoice workflows for agent-facing services, while keeping settlement direct to the project wallet.
Core capabilities
Paywall MCP tools
Charge per tool invocation on an MCP server using the same x402 payment handshake. This lets agent tools become paid actions without changing the protocol agents already speak.
Hosted endpoints
Host JSON or uploaded files on Loomal when you do not want to run your own backend. Loomal serves the content at a paywalled URL that agents can pay to access.
Per-call pricing in USDC
Use per-request pricing in USDC, from a tenth of a cent to a dollar according to the homepage. The product is positioned around micropayments that are difficult to charge with cards.
On-chain settlement and receipts
Settle payments on Base and receive a signed Ed25519 receipt for each sale. The site says funds land directly in your wallet and can be cashed out anytime.
Current and upcoming surfaces
Support flows for current developer integrations and upcoming commerce integrations. The site lists the Paywall API, MCP tools, and hosted endpoints as available now, with Shopify and WooCommerce marked coming soon.
Practical ways to use Loomal
Monetize an API endpoint
Add a payment gate to a paid API response so an agent pays before your endpoint returns premium data, analysis, or another result.
Bill for MCP tool usage
Charge AI clients for each tool invocation on an MCP server, using the same payment handshake for tools that agents already call.
Sell hosted content without server maintenance
Publish a dataset, JSON payload, or file behind a paywalled URL when you do not want to maintain a separate backend.
Launch with simple usage-based pricing
Start with the free plan and move to a paid monthly tier when call volume grows, while keeping the same paywall flow and wallet-based settlement.
Plan for future commerce storefront integrations
Prepare for storefront agent checkout on Shopify, or review the WooCommerce path that the site says is coming soon.
