# 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 [portal.jup.ag](https://portal.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

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

const API_KEY = process.env.JUPITER_API_KEY!;  // from portal.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;
}
```

## Intent Router (first step)

| User intent | API family | First action |
|---|---|---|
| Swap/quote | [Swap](#swap) | `GET /swap/v2/order` -> sign -> `POST /swap/v2/execute` |
| Lend/borrow/yield | [Lend](#lend) | `POST /lend/v1/earn/deposit` or `/withdraw` |
| Leverage/perps | [Perps](#perps) | On-chain via Anchor IDL (no REST API yet) |
| Limit orders | [Trigger](#trigger-limit-orders) | JWT auth -> `POST /trigger/v2/orders/price` |
| DCA/recurring buys | [Recurring](#recurring-dca) | `POST /recurring/v1/createOrder` -> sign -> `POST /recurring/v1/execute` |
| Token search/verification | [Tokens](#tokens) | `GET /tokens/v2/search?query={mint}` |
| Price lookup | [Price](#price) | `GET /price/v3?ids={mints}` |
| Portfolio/positions | [Portfolio](#portfolio) | `GET /portfolio/v1/positions/{address}` |
| Prediction market integration | [Prediction Markets](#prediction-markets) | `GET /prediction/v1/events` -> `POST /prediction/v1/orders` |
| Invite send/clawback | [Send](#send) | `POST /send/v1/craft-send` -> sign -> send to RPC |
| Token creation/fees | [Studio](#studio) | `POST /studio/v1/dbc-pool/create-tx` -> upload -> submit |
| Vesting/distribution | [Lock](#lock) | On-chain program `LocpQgucEQHbqNABEYvBvwoxCPsSbG91A1QaQhQQqjn` |
| DEX/RFQ integration | [Routing](#routing) | Choose DEX (AMM trait) vs RFQ (webhook) path |

### 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](#rate-limits))
- **Endpoints**: `/order` (GET), `/execute` (POST), `/build` (GET, Metis-only raw instructions)
- **Routing**: 4 routers compete — Metis (API value: `iris`), JupiterZ (`jupiterz`), Dflow (`dflow`), OKX (`okx`). 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](https://dev.jup.ag/docs/swap/v2/advanced/gasless.md) 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. `referralAccount`/`referralFee`/`receiver` disable JupiterZ only (Metis/Dflow/OKX remain). `payer` reduces routing to Metis only (per gasless docs; routing docs group all four as disabling JupiterZ but do not itemize the additional Dflow/OKX restriction). `/build` transactions cannot use `/execute` — self-manage via RPC.
- **Migrating from an older integration?** Use the `jupiter-swap-migration` skill.
- Refs: [Overview](https://dev.jup.ag/docs/swap/index.md) | [Order & Execute](https://dev.jup.ag/docs/swap/v2/order-and-execute.md) | [Build](https://dev.jup.ag/docs/swap/v2/build/index.md) | [Fees](https://dev.jup.ag/docs/swap/v2/fees.md) | [Routing](https://dev.jup.ag/docs/swap/v2/routing.md) | [Gasless](https://dev.jup.ag/docs/swap/v2/advanced/gasless.md) | [Migration](https://dev.jup.ag/docs/swap/v2/migration.md) | [OpenAPI](https://dev.jup.ag/docs/openapi-spec/swap/v2/swap.yaml)

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

| Code | Category | Meaning | Retryable | Action |
|------|----------|---------|-----------|--------|
| `0` | Success | Transaction confirmed | — | — |
| `-1` | Execute | Missing/expired cached order | Yes | Re-quote and retry |
| `-2` | Execute | Invalid signed transaction | No | Fix transaction signing |
| `-3` | Execute | Invalid message bytes | No | Fix serialization |
| `-1000` | Aggregator | Failed landing attempt | Yes | Re-quote with adjusted params |
| `-1001` | Aggregator | Unknown error | Yes | Retry with backoff |
| `-1002` | Aggregator | Invalid transaction | No | Fix transaction construction |
| `-1003` | Aggregator | Transaction not fully signed | No | Ensure all required signers |
| `-1004` | Aggregator | Invalid block height | Yes | Re-quote (stale blockhash) |
| `-2000` | RFQ | Failed landing | Yes | Re-quote and retry |
| `-2001` | RFQ | Unknown error | Yes | Retry with backoff |
| `-2002` | RFQ | Invalid payload | No | Fix request payload |
| `-2003` | RFQ | Quote expired | Yes | Re-quote and retry |
| `-2004` | RFQ | Swap rejected | Yes | Re-quote, possibly different route |
| `429` | Rate limit | Rate limited | Yes | Exponential backoff, wait 10s window |

### 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](https://dev.jup.ag/docs/lend/index.md) | [Earn](https://dev.jup.ag/docs/lend/earn.md) | [SDK](https://dev.jup.ag/docs/lend/sdk.md) | [OpenAPI](https://dev.jup.ag/docs/openapi-spec/lend/lend.yaml)

---

### 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](https://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](https://dev.jup.ag/docs/perps/index.md) | [Position account](https://dev.jup.ag/docs/perps/position-account.md) | [Position request](https://dev.jup.ag/docs/perps/position-request-account.md)

---

### 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), `POST /deposit/craft` (returns `transaction` + `requestId`), 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`. Response field is `id` (not `orderId`).

---

### 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](https://dev.jup.ag/docs/recurring/index.md) | [Create](https://dev.jup.ag/docs/recurring/create-order.md) | [Get orders](https://dev.jup.ag/docs/recurring/get-recurring-orders.md) | [Best Practices](https://dev.jup.ag/docs/recurring/best-practices) | [OpenAPI](https://dev.jup.ag/docs/openapi-spec/recurring/recurring.yaml)

- **Gotchas**: Use mint address as primary identity; treat symbol/name as convenience. Surface `audit.isSus` and `organicScore` in UX.
- Refs: [Overview](https://dev.jup.ag/docs/tokens/index.md) | [Token info v2](https://dev.jup.ag/docs/tokens/v2/token-information.md) | [OpenAPI](https://dev.jup.ag/docs/openapi-spec/tokens/v2/tokens.yaml)

- **Triggers**: `price`, `valuation`, `price feed`
- **Limit**: Max 50 mint IDs per request
- **Endpoints**: `/price/v3?ids={mints}` (GET, comma-separated)
- **Gotchas**: Tokens with unreliable pricing return `null` or are omitted (not an error). Fail closed on missing/low-confidence data for safety-sensitive actions. Use `confidenceLevel` field.
- Refs: [Overview](https://dev.jup.ag/docs/price/index.md) | [Price v3](https://dev.jup.ag/docs/price/v3.md) | [OpenAPI](https://dev.jup.ag/docs/openapi-spec/price/v3/price.yaml)

- Refs: [Lock overview](https://dev.jup.ag/docs/lock/index.md)

---

### Routing

- **Triggers**: `dex integration`, `rfq integration`, `routing engine`
- **Engines**: Juno (meta-aggregator), Iris (multi-hop DEX routing, powers Swap API), JupiterZ (RFQ market maker quotes)
- **DEX Integration** (into Iris): Free, no fees. Prereqs: code health, security audit, market traction. Implement `jupiter-amm-interface` crate. **Critical**: No network calls in implementation (accounts are pre-batched and cached). Ref impl: [github.com/jup-ag/rust-amm-implementation](https://github.com/jup-ag/rust-amm-implementation)
- **RFQ Integration** (JupiterZ): Market makers host webhook at `/jupiter/rfq/quote` (POST, 250ms), `/jupiter/rfq/swap` (POST), `/jupiter/rfq/tokens` (GET). Reqs: 95% fill rate, 250ms response, 55s expiry. SDK: [github.com/jup-ag/rfq-webhook-toolkit](https://github.com/jup-ag/rfq-webhook-toolkit)
- **Market Listing**: Instant routing for tokens < 30 days old. Normal routing (checked every 30 min) requires < 30% loss on $500 round-trip OR < 20% price impact comparing $1k vs $500.
- Refs: [Overview](https://dev.jup.ag/docs/routing/index.md) | [DEX integration](https://dev.jup.ag/docs/routing/dex-integration.md) | [RFQ integration](https://dev.jup.ag/docs/routing/rfq-integration.md) | [Market listing](https://dev.jup.ag/docs/routing/market-listing.md)

---

## Rate Limits

**Swap API** (dynamic, volume-based):

| 24h Execute Volume | Requests per 10s window |
|--------------------|-------------------------|
| $0 | 50 |
| $10,000 | 51 |
| $100,000 | 61 |
| $1,000,000 | 165 |

Quotas recalculate every 10 minutes. Pro plan does NOT increase Swap API limits.

**Other APIs**: Managed at portal level. Check [portal rate limits](https://dev.jup.ag/docs/portal/rate-limit.md).

**On HTTP 429**: Exponential backoff with jitter: `delay = min(baseDelay * 2^attempt + random(0, jitter), maxDelay)`. Wait for 10s sliding window refresh. Do NOT burst aggressively.

## Production Hardening

1. **Auth**: Fail fast if `x-api-key` is missing or invalid.
2. **Timeouts**: 5s for quotes, 30s for executions, plus total operation timeout.
3. **Retries**: Only transient/network/rate-limit failures with exponential backoff + jitter.
4. **Idempotency**: Swap `/execute` accepts same `signedTransaction` + `requestId` for up to 2 min without duplicate execution.
5. **Validation**: Validate mint addresses, amount precision, and wallet ownership before calls.
6. **Safety**: Enforce slippage and max-amount guardrails from app config.
7. **Observability**: Log `requestId`, API family, endpoint, latency, status, and error code.
8. **UX resilience**: Return actionable states (`retry`, `adjust params`, `insufficient balance`, `rate limited`).
9. **Consistency**: Reconcile async states (submitted vs confirmed vs failed) before final user success.
10. **Freshness**: Re-fetch referenced docs when behavior differs from expected flow.

## Integration Best Practices

1. Start from the API-specific overview before coding endpoint calls.
2. Enforce auth as a hard precondition for every request. Ref: [Portal setup](https://dev.jup.ag/docs/portal/setup.md)
3. Design retry logic around documented rate-limit behavior, not fixed assumptions. Ref: [Rate limits](https://dev.jup.ag/docs/portal/rate-limit.md)
4. Map all non-success responses to typed app errors using documented response semantics. Ref: [API responses](https://dev.jup.ag/docs/portal/responses.md)
5. For order-based products (Swap/Trigger/Recurring), separate create/execute/retrieve phases in code and logs.
6. Treat network/service health as part of runtime behavior (degrade gracefully). Ref: [Status page](https://status.jup.ag/)

## Cross-Cutting Error Pattern

```typescript
interface JupiterResult<T> {
  ok: boolean;
  result?: T;
  error?: { code: string | number; message: string; retryable: boolean };
}

async function jupiterAction<T>(action: () => Promise<T>): Promise<JupiterResult<T>> {
  try {
    const result = await action();
    return { ok: true, result };
  } catch (error: any) {
    const code = error?.code ?? error?.status ?? 'UNKNOWN';

    // Rate limit — retry with backoff
    if (code === 429 || code === 'RATE_LIMITED') {
      return { ok: false, error: { code: 'RATE_LIMITED', message: 'Rate limited', retryable: true } };
    }

    // Swap execute errors (negative codes)
    if (typeof code === 'number' && code < 0) {
      const retryable = [-1, -1000, -1001, -1004, -2000, -2001, -2003, -2004].includes(code);
      return { ok: false, error: { code, message: error?.error ?? 'Execute failed', retryable } };
    }

    // Program errors (positive codes like 6001 = slippage)
    if (typeof code === 'number' && code > 0) {
      return { ok: false, error: { code, message: error?.error ?? 'Program error', retryable: false } };
    }

    return { ok: false, error: { code, message: error?.message ?? 'UNKNOWN_ERROR', retryable: false } };
  }
}

async function withRetry<T>(action: () => Promise<T>, maxRetries = 3): Promise<T> {
  for (let attempt = 0; attempt <= maxRetries; attempt++) {
    const result = await jupiterAction(action);
    if (result.ok) return result.result!;

## Complete Working Examples

Production-ready code snippets. Each example uses the `jupiterFetch` helper from the sections above; apply `withRetry` around execute calls in production.

- [Swap: End-to-End](./examples/swap.md) — Order -> sign -> execute -> confirm flow
- [Lend: USDC Deposit](./examples/lend.md) — Deposit into Jupiter Lend earn pool
- [Trigger: Limit Order](./examples/trigger.md) — Create and execute a limit order
- [Price: Multi-Token Lookup](./examples/price.md) — Fetch prices with confidence filtering

## Fresh Context Policy

Always fetch the freshest context from referenced docs/specs before executing a playbook.

1. Resolve intent with `Intent Router`.
2. Before coding, fetch the playbook's linked refs (overview + API-specific docs).
3. If needed for validation or ambiguity, fetch the OpenAPI spec.
4. Treat fetched docs as source of truth over cached memory.
5. If fetched docs conflict with this file, follow fetched docs and note the mismatch.
6. If docs cannot be fetched, state that context is stale/unverified and continue with best-known guidance.
7. Keep auth invariant: `x-api-key` is required for Jupiter REST endpoints (not on-chain-only flows like Perps/Lock).
