Can I monetize any REST API with Opsalis?

Yes. Any REST API can be registered on the Opsalis marketplace without code changes. The control center wraps your endpoint and handles authentication, billing, and settlement automatically.

How is payment handled for REST API calls?

Every API call is settled in USDC on Base L2. The API owner sets the price per call, the platform takes a 5% fee, and the owner receives 95% instantly on-chain.

What latency does the P2P relay add?

The Opsalis P2P layer typically adds under 50ms of overhead. Cross-geography calls (e.g., London to New York) complete in under 100ms total.

How It Works

Data flow: Your browser → London consumer node → encrypted P2P → NYC owner node (New York) → mock REST API → JSON response returned via same path. Settlement on Base L2.

Why REST APIs on Opsalis?

Any REST API can be monetized through Opsalis without code changes. Set your price, register your endpoint, and start earning per call. The marketplace handles authentication, billing, and on-chain settlement so you can focus on building great APIs.

Whether you run a weather service, financial data feed, or machine learning inference endpoint, Opsalis turns your REST API into a revenue stream. Consumers pay per call in USDC on Base L2 — no invoicing, no payment disputes, no 30-day net terms.

Real-world example: A stock market data provider registers their ticker API. A fintech startup in another country subscribes and starts making calls. Each call costs $0.001, settled instantly on-chain. The provider earns 95% of every call, with the 5% platform fee covering infrastructure and settlement.
