Monetize Your API. Zero Code Changes.

Set your price per call, receive 100% in USDC, and let the smart contract handle payments. Your API works exactly as-is.

Four Steps to Revenue

From zero to earning on your API in under five minutes.

1

Install Handler

Pull our Docker handler and run it anywhere. Takes 2 minutes.

2

Point at Your API

Enter your API server's LAN address. Upload your spec file (OpenAPI, GraphQL SDL, WSDL, .proto, or method list).

3

Set Your Price

Choose your per-call price in USDC. You receive 100% of your stated price.

4

Start Earning

Consumers pay per call via smart contract. USDC goes straight to your wallet.

The Opsalis Protocol

Data flows encrypted between handlers. Payments settle on-chain. Your API server is never exposed to the internet.

Opsalis protocol flow: Consumer App to Consumer Handler to Owner Handler to Owner API, with USDC payments via Base L2 smart contract

Built for API Owners

Keep 100% of your price, stay private, and never modify your code.

100% of Your Price

You set your per-call price (e.g. $0.01, $0.50, $5.00). You receive every cent. A 5% IP royalty for the Opsalis software is charged separately to the consumer.

Non-Custodial

Funds go directly to your wallet via the smart contract. We never hold, touch, or control your money. Withdraw anytime — no delays, no exit fees.

Zero Knowledge

We never see your API parameters, responses, or customer data. All payloads are end-to-end encrypted between consumer and owner handlers.

Your API Stays Private

Your API server lives on your LAN. Only your handler talks to it. The handler is the only thing exposed — your infrastructure stays invisible.

Your API Works As-Is

No code changes needed. The handler bridges any protocol automatically. Consumers always see clean OpenAPI.

Also a Consumer?

The same handler lets you call any API on the marketplace. Browse, call, and pay per use.
