Base URL: https://conc-exe.xyz

Auth: None required. Optional X-Agent-Id: agt_… after agent registration.

Price: 0.10 USDC per call (100000 atomic) · publish signal 1.00 USDC

1. POST with JSON body → 402 + PAYMENT-REQUIRED header (base64 requirements)
2. Sign USDC on Solana or Base — primary facilitator facilitator.payai.network, fallback x402.dexter.cash (Solana 402 lists both fee payers)
3. Retry same request with PAYMENT-SIGNATURE header
4. 200 → JSON response + PAYMENT-RESPONSE settlement header

Use an x402 HTTP client to automate steps 2–3. See Quickstart. For native SPL tokens, see Token Pay (Beta).

Register your token so users pay with your SPL on supported x402 routes (default: POST /api/concierge).

1. Add your row to TOKEN_PAY_MERCHANTS_JSON in .env (local) or Vercel env (production) and redeploy
2. Ensure payTo has an ATA; set fallbackUsd or DexScreener price
3. Verify GET /api/token-pay?merchant=YOUR_ID → readiness.acceptReady: true
4. Wire x402 client: select accept with extra.merchantId + extra.settlement: "self"
5. Monitor on /agent/token-pay

# 1) Payment challenge
curl -s -X POST "https://conc-exe.xyz/api/concierge-intel-momentum" \
  -H "Content-Type: application/json" \
  -d '{"message":"BTC altcoin volatility","limit":5,"includeInsider":true}' \
  -D - -o /dev/null | head -15

# 2) After x402 client pays — same body + PAYMENT-SIGNATURE header → 200 JSON

Alpha body fields: message, optional chain, limit (1–8), includeInsider (default true).

Call from your backend or agent worker (recommended — avoids browser CORS). Use your x402 SDK of choice; pseudocode:

const origin = "https://conc-exe.xyz";
const body = { chain: "solana", project: "meteora" };

// x402Client wraps: POST → 402 → sign → retry
const res = await x402Client.fetch(`${origin}/api/concierge-intel-yields`, {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "X-Agent-Id": "agt_your_agent_id", // optional
  },
  body: JSON.stringify(body),
});

const data = await res.json(); // { ok, pools, dataAsOf, ... }

import httpx

ORIGIN = "https://conc-exe.xyz"
payload = {"message": "Solana airdrop themes", "limit": 5}

# Use PayAI / x402 Python helper for payment round-trip
r = httpx.post(f"{ORIGIN}/api/concierge-intel-airdrop", json=payload)
# First response: 402 — decode PAYMENT-REQUIRED, settle, retry with PAYMENT-SIGNATURE

• Server-side proxy — Browsers on foreign origins may hit CORS; agents should call Concierge from a backend.
• Idempotency — Each paid call is independent; cache Intel JSON by dataAsOf if you poll.
• Insider layer — Alpha + verdict routes weight Lounge creator signals; publish signals to improve alpha quality.
• Distribution — Optional proxy via Corbits Marketplace, list on MPPscan, MCP Registry, or pay.sh pay-skills catalog.
