Jupiter API Integration

Single skill for all Jupiter APIs, optimized for fast routing and deterministic execution.

Base URL: https://api.jup.ag Auth: x-api-key from developers.jup.ag (required for Jupiter REST endpoints)

Use/Do Not Use

Use when:

• The task requires choosing or calling Jupiter endpoints.
• The task involves swap, lending, perps, orders, pricing, portfolio, send, studio, lock, or routing.
• The user needs debugging help for Jupiter API calls.

Do not use when:

• The task is generic Solana setup with no Jupiter API usage.
• The task is UI-only with no API behavior decisions.
• The agent context is not DeFi/crypto (generic triggers like buy, sell, trade assume a DeFi domain).

Triggers: swap, quote, gasless, best route, buy, sell, trade, convert, token exchange, jupiter api, jup.ag, ultra, metis, ultra swap, ultra api, ultra-api.jup.ag, lend, borrow, earn, yield, apy, deposit, liquidation, perps, leverage, long, short, position, futures, margin trading, limit order, trigger, price condition, dca, recurring, scheduled swaps, token metadata, token search, verification, shield, price, valuation, price feed, portfolio, positions, holdings, prediction markets, market odds, event market, invite transfer, send, clawback, create token, studio, claim fee, vesting, distribution lock, unlock schedule, dex integration, rfq integration, routing engine, status page, health check, service health, accumulate, auto-buy

Developer Quickstart

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

const API_KEY = process.env.JUPITER_API_KEY!;  // from developers.jup.ag
if (!API_KEY) throw new Error('Missing JUPITER_API_KEY');
const BASE = 'https://api.jup.ag';
const headers = { 'x-api-key': API_KEY };

async function jupiterFetch<T>(path: string, init?: RequestInit): Promise<T> {
  const res = await fetch(`${BASE}${path}`, {
    ...init,
    headers: { ...headers, ...init?.headers },
  });
  if (res.status === 429) throw { code: 'RATE_LIMITED', retryAfter: Number(res.headers.get('Retry-After')) || 10 };
  if (!res.ok) {
    const raw = await res.text();
    let body: any = { message: raw || `HTTP_${res.status}` };
    try {
      body = raw ? JSON.parse(raw) : body;
    } catch {
      // keep text fallback body
    }
    throw { status: res.status, ...body };
  }
  return res.json();
}

// Sign and send any Jupiter transaction
async function signAndSend(
  txBase64: string,
  wallet: Keypair,
  connection: Connection,
  additionalSigners: Keypair[] = []
): Promise<string> {
  const tx = VersionedTransaction.deserialize(Buffer.from(txBase64, 'base64'));
  tx.sign([wallet, ...additionalSigners]);
  const sig = await connection.sendRawTransaction(tx.serialize(), {
    maxRetries: 0,
    skipPreflight: true,
  });
  return sig;
}
