Loomal

Freemium

Payments layer for agentic commerce — paywall any API, MCP tool, or store so AI agents can pay in USDC on Base per request.

Five-Line Paywall SDK: Wrap any Express, Hono, Next.js, or FastAPI handler with requirePayment to charge agents per call.
x402 Protocol Support: Uses HTTP 402 Payment Required as a real payment rail, so auth and payment happen in one round trip with no API keys.
USDC on Base Settlement: Payments settle on-chain in seconds; sellers keep custody of funds in their own wallet.
Per-Request Micropayments: Charge anywhere from a tenth of a cent to a dollar per call, enabling models the card networks cannot serve.
Signed Receipts: Every sale returns an Ed25519 receipt sellers can verify offline for provable, auditable revenue.
Hosted Endpoint Option: Paste JSON or upload a file and Loomal will host and paywall it at a URL agents can pay to hit.
Marketplace Discovery: A public marketplace lets agents discover paid APIs and MCP tools hosted through Loomal.
Broad Agent Compatibility: Works with any agent runtime that speaks x402 — Claude, GPT, Gemini, LangChain, CrewAI, MCP clients.

Monetizing an API: Turn a paid tier of a REST API into per-call micropayments that agents can buy without human onboarding.
Selling MCP Tools: Charge for premium MCP tools that agents in Claude Code, Cursor, or Windsurf install.
Data Vendor Distribution: Let agents buy scraped or curated datasets per query with no contracts or seats.
Hosted Content Paywalls: Sell access to a hosted JSON endpoint or uploaded file to agents that discover it in Loomal's marketplace.
Storefront Access (Coming): Add agentic checkout to a Shopify or WooCommerce store so AI shopping agents can transact directly.
