OmniAPI

Why OmniAPI

Let your AI agent access any API — instantly

⚡

Zero setup

No registration, no API keys, no OAuth flows. Install the skill and your agent is ready to call real-world APIs in seconds.

💰

Pay only for what you use

Each request costs $0.001 in USDC. No monthly subscriptions, no rate limit tiers, no surprise invoices. True pay-as-you-go.

🔒

No credentials to leak

Your agent never stores API keys. Payment is the authentication. Nothing to rotate, nothing to revoke, nothing to breach.

🌐

Open protocol

Built on the x402 HTTP payment standard and USDC on Base. No vendor lock-in. Any agent, any wallet, any chain that supports x402.

The difference

Traditional APIs vs OmniAPI

Manage dozens of API keys

Risk credential leaks from your agent
Handle OAuth, rate limits, key rotation

One skill install, all APIs available
No keys — payment is the auth
$0.001 per request, nothing more
No credentials stored, nothing to leak
Just call the endpoint and get data
