It is one of 11 DeFi intelligence endpoints offered by Silverback's x402 API. You supply an input mint address, output mint address, and amount (in base units/lamports), and receive a quote with output amounts, price impact, route plan, and fee breakdown.\n\nThe endpoint uses the x402 micropayment protocol: an initial request returns a 402 Payment Required response with payment options. You then sign a USDC authorization (on Base, Solana, or SKALE) and resend with the payment proof header. Each call costs $0.01 in USDC. The endpoint is a GET request with query parameters, making it straightforward for agents to integrate. An optional slippageBps parameter (default 50 = 0.5%) controls slippage tolerance.\n\nSilverback positions itself as autonomous DeFi infrastructure for the agent economy, offering intelligence services like swap routing, liquidity analysis, yield optimization, and market data. All endpoints return JSON with a `success` boolean field. Payment can also be made with the $BACK token on Base via Permit2 for a 15% discount.","tags":[],"capabilities":["jupiter-dex-quote","solana-swap-routing","x402-micropayment","price-impact-analysis","slippage-control","defi-intelligence","pay-per-use"],"categories":["defi","crypto","trading"],"synonyms":["Jupiter aggregator quote","Solana swap quote","Solana DEX quote","Jupiter route API","Solana token swap pricing","Jupiter v6 quote","SPL token swap quote"],"warnings":["External docs at https://docs.silverbackdefi.app/ were not crawled; the /docs path on the x402 subdomain returns 404.","Response schema is inferred — no actual 200 response body was captured in the probe.","The example response JSON is illustrative based on Jupiter's known format and may not exactly match Silverback's wrapper output."],"endpointUrl":"https://x402.silverbackdefi.app/api/v1/jupiter-quote","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xD34411a70EffbDd000c529bbF572082ffDcF1794","amount":"10000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"8wLKe8H59eni5DmERU27GiRHGnN9fogRoq9yNqyKKNJA"},"payTo":"4HVvnhyXTkMnPbMBo9r3kfvYhzW4JSbLGdXg9SkUcVSe","amount":"10000","scheme":"exact","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","maxTimeoutSeconds":300},{"asset":"0x85889c8c714505E0c94b30fcfcF64fE3Ac8FCb20","extra":{"name":"USD Coin","version":"1"},"payTo":"0xD34411a70EffbDd000c529bbF572082ffDcF1794","amount":"10000","scheme":"exact","network":"eip155:1187947933","maxTimeoutSeconds":300},{"asset":"USDC","extra":{"symbol":"USDC","nodeUrl":"https://api.keeta.com","decimals":6,"serverAddress":"keeta_aabwgiqyij4scwktdoczzvhpi33btieeses5sezeqzqmpi5ik76ttyegwuvfsai","permissionSetupUrl":"/api/v1/keeta/setup-permission"},"payTo":"keeta_aabaolle2k3hceayy4vkyw7smgl35o5wbqeebt2fibyx5sxxodneqb2rmwqkjci","amount":"10000","scheme":"keeta-usdc","network":"keeta:main","expiresAt":1771370260955,"paymentId":"820dca0d-a595-41f1-b7d8-bdee39086f27","amountHuman":"0.010000","description":"Get a swap quote from Jupiter aggregator for Solana tokens.
