Turn any API into a paid API.

Aegis is a drop-in edge gateway. Set a price per route in USD; AI agents pay in USDC over x402 and you get paid on every call.

API monetization shouldn’t require a billing team.

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.

1
Connect your API
Enter your backend URL and paste your API key. Aegis encrypts and stores it.

GET /v1/forecast$0.001

Point your domain
Add a CNAME record. Aegis provisions TLS and starts routing. Agents pay, you earn.

Pay per request with x402
Aegis uses the x402 payment standard, the protocol Coinbase built for machine-to-machine payments. Agents pay per request in USDC. No buyer signup. No subscriptions. Just HTTP.
HTTP 402 · USDC
Multi-chain payments
Your API accepts payments on Base and Solana out of the box. Buyers pick their network. You set the price once in USD and Aegis handles the rest.
Base · Solana
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.

Real-time dashboard
Watch paid calls land as they happen: requests, revenue per route and settlement status, updated live.
Live, per route
Your domain, your brand
Point api.yourdomain.com at Aegis. TLS certificates are automatic. Your customers call your domain and Aegis stays invisible.

Production-grade edge
Replay prevention, idempotency locks, black-hole credit protection and automatic 429 preemption. If your upstream fails after payment, buyers retry for free.
