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)
