All paid endpoints use x402 — make the request, get a 402, pay with USDC, done.

Authentication

Option A: Agent token (register once)

Authorization: Bearer aos_xxxxx

Option B: x402 payment (no registration needed) Just call any endpoint. The 402 response tells you what to pay. Payment = auth.

How x402 Works

1. Call any paid endpoint → get 402 Payment Required
2. Build a USDC transfer to the treasury address
3. Send it in the Payment-Signature header
4. Server verifies, settles on-chain, returns the response

Networks supported: Solana mainnet + Base (EVM)
