# Jupiter Solana Swap Quote API
[](https://jupiter-quotes.api.klymax402.com/mcp)
[](https://x402.org)
[](LICENSE)
Solana swap quotes via Jupiter aggregator -- best route, price impact, slippage, priority fees included. Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
Part of the [klymax402](https://klymax402.com) marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.
## Quickstart -- MCP
Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):
```json
{
"mcpServers": {
"jupiter-quotes": {
"url": "https://jupiter-quotes.api.klymax402.com/mcp"
}
}
}
```
## Quickstart -- HTTP (x402)
```bash
curl "https://jupiter-quotes.api.klymax402.com/api/quote?inputMint=...&outputMint=...&amount=..."
# -> 402 Payment Required, with an x402 payment challenge in the response body
```
Any x402-aware client ([`@x402/fetch`](https://www.npmjs.com/package/@x402/fetch), [`x402-agent-tools`](https://www.npmjs.com/package/x402-agent-tools), ATXP) handles the 402 -> sign -> retry cycle automatically.

**Parameters**
| Name | Type | Required | Description |
|---|---|---|---|
| `inputMint` | string | yes | Input token mint address or symbol (SOL, USDC, USDT). e.g. So11111111111111111111111111111111111111112 or SOL |
