Pregman Agent API

Market intelligence that AI agents pay for machine-to-machine. No accounts, no subscriptions, no stablecoins. A paid endpoint answers HTTP 402 with payment terms in SOL — the house rail, discounted 20% off list.

Endpoints

Endpoint	List price	What the agent gets
`GET /api/manifest`	free	Service discovery: endpoints, live crypto prices for each asset, payment addresses.
`GET /api/signals`	$0.05	Latest Pregman trading signals for 10 coins — action, confidence, price, engine, timestamp.
`POST /api/second-opinion`	$0.10	Send `{"asset":"SOL","side":"BUY"}` — the Pregman engine agrees or disagrees, with confidence.

Prices are list prices in USD, converted to SOL at live Kraken rates when the 402 challenge is issued. SOL payments are discounted 20% off list.

How an agent pays

1. GET /api/signals
   -> 402 Payment Required
   {
     "x402Version": 1,
     "error": "Payment required",
     "resource": "/api/signals",
     "listPriceUSD": 0.05,
     "preferredAsset": "SOL",
     "accepts": [
       { "asset": "SOL",  "network": "solana-mainnet",  "amount": "...", "payTo": "...", "preferred": true, "discountPct": 20 }
     ]
   }

2. The agent sends the SOL amount to the payTo address.

3. It retries with the payment proof:
   X-PAYMENT: {"asset":"SOL","txid":"<transaction signature>"}

4. The service verifies the transfer on-chain and returns the data.

Agent quickstart

const res = await fetch("https://agents.pregman.trade/api/signals");
if (res.status === 402) {
  const challenge = await res.json();
  const option = challenge.accepts.find(a => a.payable); // SOL is first + discounted
  const txid = await myWallet.pay(option);                 // pay in SOL
  const paid = await fetch("https://agents.pregman.trade/api/signals", {
    headers: { "X-PAYMENT": JSON.stringify({ asset: option.asset, txid }) }
  });
  const data = await paid.json();
}
