Integrating Jupiter

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).

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;
}

Token Amounts & Decimals

Every Jupiter amount field is in the token's smallest unit (raw integer) — never a human/UI value.

• Common decimals: SOL & wSOL = 9, USDC & USDT = 6. Canonical mints: SOL So11111111111111111111111111111111111111112, USDC EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v.
• Convert human → raw: raw = Math.round(human * 10 ** decimals). Examples: 1 SOL → 1_000_000_000, 100 USDC → 100_000_000. slippageBps is basis points: 0.5% = 50, 1% = 100.
• Read decimals per-mint on-chain with getMint(connection, mintPubkey) from @solana/spl-token — never hardcode (decimals vary by token), and do not call the Price API just to discover decimals.

Intent Router (first step)

API Playbooks

Use each block as a minimal execution contract. Fetch the linked refs for full request/response shapes, TypeScript interfaces, and parameter details.

Swap

• Base URL: https://api.jup.ag/swap/v2

• Triggers: swap, quote, gasless, best route

• Fee: Variable by pair — 0 bps (Jupiter tokens/pegged), 2 bps (SOL-Stable), 5 bps (LST-Stable), 10 bps (most pairs), 50 bps (tokens < 24h). Referral fees: 50-255 bps (Jupiter retains 20%).

• Rate Limit: 50 req/10s base, scales with 24h execute volume (see Rate Limits)

• Endpoints: /order (GET), /execute (POST), /build (GET, Metis-only raw instructions)

• Quote vs. execute: For a read-only quote/price preview, call GET /order and omit taker — the response transaction is null and you read outAmount, routePlan[].swapInfo.label, and price-impact fields. Pass taker (then sign + POST /execute) only when you actually intend to swap. There is no separate quote endpoint — /swap/v1/quote is deprecated; use /swap/v2/order for quotes too.

• Routing: 4 routers compete — Metis (metis), JupiterZ (jupiterz), Dflow (dflow), OKX (okx). The router response field returns one of these values. swapType is aggregator (Metis, Dflow, or OKX) or rfq (JupiterZ). Response mode field: "ultra" (all routers, default params) or "manual" (restricted by optional params). /build uses Metis only.

• Gasless: Three paths — automatic (Jupiter-covered), JupiterZ (MM-covered), integrator-payer (payer param, Metis-only routing). Eligibility varies by balance, trade size, and parameters used. See Gasless docs for current thresholds and disqualifying params.

• Gotchas:

  • Signed payloads have ~2 min TTL. Transactions are immutable after receipt.
  • Split order/execute in code and logging. Re-quote before execution when conditions may have changed.
  • Routing impact of optional params: referralAccount + referralFee disable JupiterZ only (Metis/Dflow/OKX remain); payer (integrator gasless) restricts routing to Metis only (disables JupiterZ, Dflow, and OKX); receiver does NOT restrict routing, but must differ from taker (receiver=taker returns 400 "Receiver cannot be same as taker").
  • /build transactions cannot use /execute — self-manage via RPC.

• Migrating from an older integration? Use the jupiter-swap-migration skill.

• Refs: Overview | Order & Execute | Build | Gasless | Migration | OpenAPI

  Fees are documented inline on the Order & Execute and Build pages; router competition and the parameter routing-impact matrix are on the Overview and Order & Execute pages.

Common error codes returned by /swap/v2/execute with recommended actions:

On success, /execute returns { status: "Success", code: 0, signature, inputAmountResult, outputAmountResult, slot, totalInputAmount, totalOutputAmount }. On failure it returns status: "Failed" with a non-zero code and an error string. inputAmountResult/outputAmountResult are the actual on-chain amounts; reconcile against your quote.

Lend

• Base URL: https://api.jup.ag/lend/v1
• Triggers: lend, borrow, earn, liquidation
• Programs: Earn jup3YeL8QhtSx1e253b2FDvsMNC87fDrgQZivbrndc9, Borrow jupr81YtYssSyPt8jbnGuiWon5f6x9TcDEFxYe3Bdzi
• SDK: @jup-ag/lend (TypeScript)
• Endpoints: /earn/deposit (POST), /earn/withdraw (POST), /earn/mint (POST), /earn/redeem (POST), /earn/deposit-instructions (POST), /earn/withdraw-instructions (POST), /earn/tokens (GET), /earn/positions (GET), /earn/earnings (GET)
• Gotchas: Recompute account state before each state-changing action. Encode risk checks (health factors, liquidation boundaries) as preconditions. All deposit/withdraw/mint/redeem return base64 unsigned VersionedTransaction.
• For SDK-level integration with @jup-ag/lend and @jup-ag/lend-read, use the jupiter-lend skill.
• Refs: Overview | Earn | SDK | OpenAPI

Perps

• Status: API is work-in-progress. No REST endpoints yet. Interact on-chain via Anchor IDL.
• Triggers: perps, leverage, long, short, position
• Community SDK: github.com/julianfssen/jupiter-perps-anchor-idl-parsing
• Gotchas: Max 9 simultaneous positions: 3 long (SOL, wETH, wBTC) + 6 short (3 tokens x 2 collateral USDC/USDT). Validate margin/leverage against account model.
• Refs: Overview | Position account | Position request

Trigger (Limit Orders)

• Base URL: https://api.jup.ag/trigger/v2
• Triggers: limit order, trigger, price condition
• Min order: 10 USD equivalent
• Auth: Dual-auth — x-api-key (all requests) + Authorization: Bearer <jwt> (order mutations). JWT obtained via challenge-response: POST /auth/challenge → sign challenge with wallet → POST /auth/verify → receive token. JWT expiry does NOT affect open orders — they continue executing.
• Endpoints: /auth/challenge (POST, body: walletPubkey + type), /auth/verify (POST, body: type + walletPubkey + base58 signature), /vault (GET), /vault/register (GET), /deposit/craft (POST), /orders/price (POST create, PATCH update), /orders/price/cancel/{orderId} (POST, initiates withdrawal), /orders/price/confirm-cancel/{orderId} (POST, submits signed withdrawal + cancelRequestId), /orders/history (GET, wallet implicit via JWT)
• Order types: single (one directional trigger), oco (take-profit + stop-loss pair), otoco (entry trigger + OCO). triggerCondition: "above" or "below".
• Architecture: Off-chain custodial vault (Privy) per wallet. Orders invisible on-chain until execution — MEV-resistant. Triggers on USD price (not pool rate ratios). Partial fills supported.
• Gotchas:
  • Order creation is 3 steps — GET /vault/register (register if new; returns 409 "Vault already registered" if it exists, which is fine), POST /deposit/craft (returns transaction + requestId; the body MUST include orderType: "price" and orderSubType (single/oco/otoco)), sign deposit tx, then POST /orders/price with depositRequestId + depositSignedTx.
  • Cancellation is two-step — POST /cancel/{orderId} returns transaction + requestId; sign, then POST /confirm-cancel/{orderId} with signedTransaction + cancelRequestId.
  • Create response field is id (not orderId); order history objects use orderState/rawState (no status field).

Recurring (DCA)

• Base URL: https://api.jup.ag/recurring/v1
• Triggers: dca, recurring, scheduled swaps
• Fee: 0.1% on all recurring orders
• Constraints: Min 100 USD total, min 2 orders, min 50 USD per order
• Pagination: 10 orders per page
• Endpoints: /createOrder (POST), /cancelOrder (POST), /execute (POST), /getRecurringOrders (GET)
• Gotchas: Token-2022 NOT supported. Use params.time for order scheduling; price-based ordering is not supported.
• Refs: Overview | Create | Get orders | Best Practices | OpenAPI

Tokens

• Base URL: https://api.jup.ag/tokens/v2
• Triggers: token metadata, token search, shield
• Endpoints: /search?query={q} (GET, comma-separate mints, max 100), /tag?query={tag} (GET, verified or lst), /{category}/{interval} (GET, categories: toporganicscore, toptraded, toptrending; intervals: 5m, 1h, 6h, 24h), /recent (GET)
• Gotchas:
  • Use mint address as primary identity; treat symbol/name as convenience.
  • Primary trust signal is top-level isVerified (boolean) plus organicScore (0-100) and organicScoreLabel (high/medium/low).
  • Secondary risk flag: audit.isSus — a boolean present ONLY when true (a safe token has no isSus key at all), so check it defensively as token.audit?.isSus === true, never read it directly. Verified live on flagged tokens (dev holds ~100% of supply); those also carry isVerified: null and organicScoreLabel: "low". Absence of isSus is NOT proof of safety — not all risky tokens carry the flag.
  • Other conditional audit fields the live API returns: mintAuthorityDisabled, freezeAuthorityDisabled, topHoldersPercentage, devBalancePercentage, devMigrations, devMints (all nullable, any may be absent; devMigrations is returned but missing from the current OpenAPI schema).
