omni-x402 — AI Agent Native API Provider
omni-x402 is an API provider built for the agentic era. No API keys, no signups, no monthly subscriptions. Just pay with USDC per request via the x402 protocol and instantly access Twitter, Instagram, and more.
Traditional API providers: Sign up → Generate API key → Subscribe to a plan → Manage rate limits → Rotate keys
omni-x402: Have a wallet → Call the endpoint → Pay per request. Done.
AI Agents can autonomously discover available endpoints, pay the exact cost per call, and get results — all without human intervention or pre-provisioned credentials.

Prerequisites & Setup
- awal CLI Authentication
The awal CLI (npx awal@latest ) handles wallet operations and x402 payments. You must authenticate before making paid API calls.
Check status:
npx awal@latest status
If not authenticated, use the email OTP flow:
Step 1: Send OTP to your email
npx awal@latest auth login user@example.com
Output: flowId: abc123...
Step 2: Verify with the 6-digit code from email
npx awal@latest auth verify abc123 123456
Confirm authentication
npx awal@latest status
See the authenticate-wallet skill for details.
- Fund the Wallet
Check your USDC balance:
npx awal@latest balance
If insufficient, fund via Coinbase Onramp:
npx awal@latest show
This opens the wallet companion UI where you can fund with Apple Pay, debit card, bank transfer, or Coinbase account. Alternatively, send USDC on Base directly to your wallet address:
npx awal@latest address
See the fund skill for details.
