Gated Alpha Skill

Gated Alpha is a pay-per-call alpha marketplace. Crypto signal groups publish calls. Agents pay USDC to unlock the full payload. Group owners receive automatic onchain payouts within seconds of each purchase.

Live API: https://www.gatedalpha.xyz

Two Ways to Receive Alpha

Option A — Push (Recommended)

Register a webhook once. New matching alpha is delivered to your endpoint the moment it drops. No polling.

Option B — Pull

Poll /alpha/latest on your own schedule and fetch the ones you want.

---

Option A: Webhook Subscriptions (Push Model)

Step 1 — Register your webhook

POST https://www.gatedalpha.xyz/agents/subscribe
Content-Type: application/json

{
  "wallet": "0xYourWalletAddress",
  "webhook_url": "https://your-agent.xyz/hooks/alpha",
  "chains": ["solana", "base"],
  "categories": ["memecoin", "defi"],
  "max_price_usdc": 5
}

Response:

{
  "ok": true,
  "subscription": {
    "id": "sub_abc123",
    "wallet": "0xyourwallet",
    "webhook_url": "https://your-agent.xyz/hooks/alpha",
    "chains": ["solana", "base"],
    "categories": [],
    "max_price_usdc": 5,
    "created_at": "2026-02-26T14:00:00.000Z",
    "last_fired_at": null,
    "fire_count": 0
  }
}

Limits: Max 10 subscriptions per wallet. Dedup window: same alpha won't fire twice to the same subscription within 60 seconds. Webhook must be HTTPS.

---

Step 2 — Handle incoming webhooks

When a matching alpha drops, your endpoint receives:

POST https://your-agent.xyz/hooks/alpha
Content-Type: application/json

{
  "event": "alpha.new",
  "subscription_id": "sub_abc123",
  "sent_at": "2026-02-26T14:05:00.000Z",
  "alpha": {
    "id": "alpha_01kjXXXX",
    "group_id": "grp_01kjXXXX",
    "group_name": "Liquid Path FNF",
    "group_score": 72,
    "chain": "solana",
    "category": "memecoin",
    "price_usdc": 1,
    "mcap_range": "micro",
    "preview_text": "New Solana micro-cap play...",
    "is_new_group": false,
    "trial_url": null,
    "paid_url": "https://www.gatedalpha.xyz/alpha/alpha_01kjXXXX",
    "posted_at": "2026-02-26T14:04:55.000Z"
  }
}

Acknowledge fast. Return 200 immediately, then process async. Delivery is fire-and-forget — if your endpoint is down, the event is not retried.

---

Step 3 — Decide: trial or buy

if trial_url is present AND is_new_group is true:
  → GET trial_url first (free, no payment)
  → Evaluate the preview. If promising, proceed to purchase.

if group_score < 30:
  → Skip. Unproven group.

else:
  → Purchase via x402 (see below)

---

Step 4 — Buy the full alpha (x402)

import { wrapFetchWithPayment } from '@x402/fetch';
import { x402Client } from '@x402/core/client';
import { ExactEvmScheme } from '@x402/evm';
import { createPublicClient, createWalletClient, http } from 'viem';
import { base } from 'viem/chains';
import { privateKeyToAccount } from 'viem/accounts';

const account = privateKeyToAccount('0x<your-private-key>');

const publicClient = createPublicClient({
  chain: base,
  transport: http('https://base-rpc.publicnode.com')
});

const walletClient = createWalletClient({
  account,
  chain: base,
  transport: http('https://base-rpc.publicnode.com')
});

const clientSigner = {
  address: account.address,
  signTypedData: (msg) => walletClient.signTypedData({ account, ...msg }),
  readContract: (args) => publicClient.readContract(args)
};

const coreClient = new x402Client().register('eip155:*', new ExactEvmScheme(clientSigner));
const paidFetch = wrapFetchWithPayment(fetch, coreClient);

// Automatically handles: 402 challenge -> sign ERC-3009 -> retry with payment header
const res = await paidFetch('https://www.gatedalpha.xyz/alpha/alpha_01kjXXXX');
const alpha = await res.json();

Note: @x402/core, @x402/evm, @x402/fetch, and viem must be installed. Run from a directory where these packages exist in node_modules.

Returning buyer: If the same wallet purchases the same alpha_id again, content is served free. No double charge.

Full alpha payload (200 response after payment)

{
  "id": "alpha_01kj457g0nzqdhacwd8jn25ykq",
  "group": {
    "group_id": "grp_...",
    "display_name": "Group Name",
    "group_score": 72,
    "price_usdc": 1
  },
  "token": {
    "name": "TokenName",
    "symbol": "TKN",
    "chain": "base",
    "contract_address": "0x...",
    "pair_address": "0x..."
  },
  "market": {
    "mcap_at_call": 50200,
    "liquidity_usd": 55893,
    "age_hours": 24.7
  },
  "alpha": {
    "thesis": "Raw call text from the group",
    "catalyst": "source_telegram_message",
    "category": "memecoin",
    "confidence": 0.85,
    "risk_level": "low",
    "target_mcap": 15000000
  }
}

---

Option B: Pull (Polling)

Browse free previews

GET https://www.gatedalpha.xyz/alpha/latest?limit=20&chain=solana

Key preview fields:

• id — use to fetch the full paid payload
• group_score — quality signal (0–100), filter on this first
• chain — base, solana, ethereum, bsc, arbitrum
• category — memecoin, defi, etc.
• risk_level — "low", "medium", "high", or null
• confidence — float 0–1 or null
• mcap_range — "<100K", "100K-1M", etc.
• price_usdc — cost to unlock

Filter by default

min_group_score = 40   (skip unproven groups)
chains = ["base"]      (or your target chains)
limit = 20
skip if confidence AND risk_level are both null (unscored call)

Decision logic

if group_score < 40           → skip
if risk_level == "high"
  AND confidence < 0.7        → skip
if mcap_at_call > 5_000_000   → skip (likely too late)
else                          → candidate for purchase

Buy via x402 (same as push flow above)

Hit GET /alpha/{id} — it returns 402 with the payment challenge. Use @x402/fetch to handle automatically. See Step 4 above.

---

Manage Subscriptions

List your subscriptions

GET https://www.gatedalpha.xyz/agents/{wallet}/subscriptions

Delete a subscription

DELETE https://www.gatedalpha.xyz/agents/unsubscribe
Content-Type: application/json

{
  "wallet": "0xYourWallet",
  "subscription_id": "sub_abc123"
}

---

Free Trial Endpoints

If a group has zero purchases, a free trial is available:

GET https://www.gatedalpha.xyz/alpha/{id}/trial

Returns a redacted preview — no payment required. Use this to evaluate new groups before committing.

When trial_url is present in a webhook payload or a 402 response, always check it first.

---

Minimal Webhook Handler (Node.js)

import express from 'express';
import { wrapFetchWithPayment } from '@x402/fetch';

const app = express();
app.use(express.json());

app.post('/hooks/alpha', async (req, res) => {
  const { alpha } = req.body;
  res.sendStatus(200); // Acknowledge immediately

  if (alpha.group_score < 30) return; // Skip low-trust groups

  // Free trial if available (new group, no track record yet)
  if (alpha.trial_url) {
    const trial = await fetch(`https://www.gatedalpha.xyz${alpha.trial_url}`);
    const preview = await trial.json();
    // Evaluate preview — if not interesting, return early
    if (!isWorthBuying(preview)) return;
  }

  // Buy the full alpha
  const res2 = await paidFetch(alpha.paid_url); // paidFetch from Step 4
  const content = await res2.json();
  // Your trading logic here
});

app.listen(3000);
