Pay-per-call via [x402](https://x402.org) (USDC on Base L2) -- no API key, no signup, no rate-limit wall.\n\nPart of the [klymax402](https://klymax402.com) marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.\n\n## Quickstart -- MCP\n\nAdd to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):\n\n```json\n{\n  \"mcpServers\": {\n    \"jupiter-quotes\": {\n      \"url\": \"https://jupiter-quotes.api.klymax402.com/mcp\"\n    }\n  }\n}\n```\n\n## Quickstart -- HTTP (x402)\n\n```bash\ncurl \"https://jupiter-quotes.api.klymax402.com/api/quote?inputMint=...&outputMint=...&amount=...\"\n# -> 402 Payment Required, with an x402 payment challenge in the response body\n```\n\nAny 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.\n\n## Tools\n\n| Tool | Method | Path | Price | Description |\n|---|---|---|---|---|\n| `jupiter_get_swap_quote` | GET | `/api/quote` | $0.005 | Get best swap quote on Solana via Jupiter aggregator |\n| `jupiter_get_swap_quote` | POST | `/api/quote` | $0.005 | Get best swap quote on Solana via Jupiter aggregator (POST variant) |\n\n### `jupiter_get_swap_quote`\n\nUse this when you need a swap quote on Solana. Returns the best route via Jupiter aggregator across all Solana DEXes with price impact and fee analysis.\n\n**Parameters**\n\n| Name | Type | Required | Description |\n|---|---|---|---|\n| `inputMint` | string | yes | Input token mint address or symbol (SOL, USDC, USDT). e.g. So11111111111111111111111111111111111111112 or SOL |\n| `outputMint` | string | yes | Output token mint address or symbol (SOL, USDC, USDT). e.g. EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v or USDC |\n| `amount` | string | yes | Amount in raw lamports/smallest unit. e.g. 1000000000 = 1 SOL, 1000000 = 1 USDC |\n| `slippage` | number | no | Slippage tolerance in basis points. Default 50 (0.5%). e.g. 100 = 1% |\n\n**Returns**\n\n- `inputToken` -- input token symbol and mint address\n- `outputToken` -- output token symbol and mint address\n- `inAmount` -- input amount in raw units\n- `outAmount` -- expected output amount in raw units\n- `priceImpact` -- price impact percentage (e.g. 0.12 = 0.12%)\n- `minimumReceived` -- minimum output after slippage tolerance\n- `route` -- array of DEX hops used (e.g. Raydium -> Orca)\n- `priorityFee` -- recommended priority fee in lamports\n\nExample response:\n\n```json\n{\"inputToken\":{\"symbol\":\"SOL\",\"mint\":\"So111...\"},\"outputToken\":{\"symbol\":\"USDC\",\"mint\":\"EPjF...\"},\"inAmount\":\"1000000000\",\"outAmount\":\"67450000\",\"priceImpact\":0.05,\"minimumReceived\":\"67112750\",\"route\":[\"Raydium V4\"],\"priorityFee\":5000}\n```\n\n**When to use**: executing any Solana token swap. Essential for getting the best price, understanding slippage, and choosing the optimal route.\n\n### `jupiter_get_swap_quote`\n\nUse this when you need a swap quote on Solana. Returns the best route via Jupiter aggregator across all Solana DEXes with price impact and fee analysis. POST variant of jupiter_get_swap_quote -- same params passed as JSON body instead of query string.\n\n**Parameters**\n\n| Name | Type | Required | Description |\n|---|---|---|---|\n| `inputMint` | string | yes | Input token mint address or symbol (SOL, USDC, USDT). e.g. So11111111111111111111111111111111111111112 or SOL |\n| `outputMint` | string | yes | Output token mint address or symbol (SOL, USDC, USDT). e.g. EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v or USDC |\n| `amount` | string | yes | Amount in raw lamports/smallest unit. e.g. 1000000000 = 1 SOL, 1000000 = 1 USDC |\n| `slippage` | number | no | Slippage tolerance in basis points.
