<!-- Quick Start -->
<div class="section">
<h2>🚀 Getting Started in 3 Steps</h2>
<p>The DeepBlue API is built for autonomous AI agents. No accounts, no rate limits on most endpoints — just pay in USDC and get data instantly.</p>
<h3>Step 1 — Get a USDC wallet (Base or Solana)</h3>
<p>You need any EVM wallet with USDC on Base (chain ID 8453), or a Solana wallet with USDC. Fund it with a few cents to get started — most calls cost $0.001–$0.01.</p>
<h3>Step 2 — Install the x402 SDK</h3>
<pre><code># JavaScript / Node.js
npm install x402-axios
# Python
pip install x402</code></pre>
<p>The SDK intercepts HTTP 402 responses and signs payments automatically from your wallet private key.</p>
<h3>Step 3 — Make your first call</h3>
<pre><code>import axios from 'axios';
import { wrapAxios } from 'x402-axios';
const client = wrapAxios(axios, { privateKey: process.env.PRIVATE_KEY });
// Get live BTC signal — costs $0.01 USDC, paid automatically
const { data } = await client.get('https://api.deepbluebase.xyz/signals');
console.log(data.signals[0]);
// → { coin: 'BTC', direction: 'UP', confidence: 0.68, regime: 'momentum' }</code></pre>
<div class="warning">

<h2>📡 How x402 Payments Work</h2>
<p>We use the <strong>x402 protocol</strong> via <a href="https://payai.network" target="_blank">PayAI facilitator</a>. Your agent pays automatically — no manual steps, no accounts.</p>

<!-- FAQs -->
<div class="section">
<h2>❓ FAQs</h2>
<h3>What networks are accepted?</h3>
<p>Both <strong>Base USDC</strong> (chain 8453) and <strong>Solana USDC</strong>. The x402 SDK picks the right one automatically based on your wallet type.</p>
<h3>Do I need to sign up?</h3>
<p><strong>No.</strong> Just have a wallet with USDC (Solana or Base). The x402 SDK handles everything automatically.</p>
<h3>Is the trading data real?</h3>
<p>Yes. Signals come directly from Fishy (our live Polymarket bot). Performance data is our actual P&L — verifiable on-chain.</p>
<h3>What if a payment fails?</h3>
<p>The request returns HTTP 402. Your wallet is not charged. Retry when your balance is sufficient.</p>
<h3>Can AI agents use this autonomously?</h3>
<p>Yes — that's the point. Use the <code>x402-axios</code> or <code>x402</code> (Python) SDK to make any AI agent pay-per-call automatically.
