API monetization shouldn’t require a billing team.

Problem

You built the API. Now you need to charge for it.

  • Traditional monetization means accounts, API keys, invoices, rate limits, and weeks of plumbing.

  • There should be a way to say “this endpoint costs $0.01” and start getting paid. That’s Aegis.

API monetization
x402 payment illustration

Pay Per Request with x402

Aegis uses the x402 payment standard — the same protocol built by Coinbase for machine-to-machine payments. Agents pay per request with USDC. No buyer signup. No subscriptions. Just HTTP.

Multi-chain payments illustration

Multi-Chain Payments

Your API accepts payments on both chains out of the box. Buyers pick their preferred network. You set the price once in USD — Aegis handles the rest.

Secure API Key Injection

Paste your upstream API key once. Aegis encrypts it with AES-256-GCM, stores it in an envelope-encrypted vault, and injects it into upstream requests at the last possible moment. It never appears in logs, responses, or error messages.
