During development, you can use the developer endpoints without an API key. For production use, request an API key for higher rate limits.
To increase, trade an input token (USDC, CASH, or any SPL) into the outcome token. To decrease, flip the mints. Both directions use the same /order endpoint.

Set up

Imports, env config, and the wallet/connection used across every step.
import "dotenv/config";

import { Connection, Keypair, VersionedTransaction } from "@solana/web3.js";
import bs58 from "bs58";

const DFLOW_TRADE_API_URL = process.env.DFLOW_TRADE_API_URL ?? "https://dev-quote-api.dflow.net";
const DFLOW_API_KEY = process.env.DFLOW_API_KEY; // optional; not needed for dev endpoints
const DFLOW_SETTLEMENT_MINT = process.env.DFLOW_SETTLEMENT_MINT ?? "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"; // USDC
const SOLANA_RPC_URL = process.env.SOLANA_RPC_URL ?? "https://api.mainnet-beta.solana.com";

const connection = new Connection(SOLANA_RPC_URL, "confirmed");

Request an order

const outcomeMint = "OUTCOME_TOKEN_MINT_ADDRESS";
const amount = 25_000_000; // 25 USDC (6 decimals)

const params = new URLSearchParams();
params.append("inputMint", DFLOW_SETTLEMENT_MINT);
params.append("outputMint", outcomeMint);
params.append("amount", amount.toString());
params.append("userPublicKey", keypair.publicKey.toBase58());

const orderResponse = await fetch(
  `${DFLOW_TRADE_API_URL}/order?${params}`,
  { headers }
).then((r) => r.json());

Sign and submit

const txBuffer = Buffer.from(orderResponse.transaction, "base64");
const transaction = VersionedTransaction.deserialize(txBuffer);

transaction.sign([keypair]);

const signature = await connection.sendRawTransaction(transaction.serialize(), {
  skipPreflight: true,
  maxRetries: 2,
});
console.log(`  Tx: https://orbmarkets.io/tx/${signature}`);

await connection.confirmTransaction({
  signature,
  blockhash: transaction.message.recentBlockhash,
  lastValidBlockHeight: orderResponse.lastValidBlockHeight,
});

Check order status

const status = await fetch(
  `${DFLOW_TRADE_API_URL}/order-status?signature=${signature}`,
  { headers }
).then((r) => r.json());

console.log(status.status, status.fills);

Settlement

Reduce orders settle via one of two paths depending on reserve balance.
When reserves are balanced, the order settles immediately. Unused outcome tokens are refunded, platform fees are transferred, and stablecoins move from the Settlement Vault to your wallet.
When reserves are not balanced, the order fills without immediate settlement. Unused outcome tokens are refunded. Later, when reserves rebalance, the settlement authority completes settlement and transfers stablecoins to your wallet.

Buy Outcome Tokens

Open or grow a prediction market position from any input token.

Redeem Outcome Tokens

Complete redemption flow including scalar outcome payouts.

Track User Positions

Map wallet balances back to markets and outcomes.

Market Lifecycle

States a market moves through and what each one allows.
