Silverback uses the x402 micropayment protocol, accepting USDC on Base, Solana, and SKALE networks. While this specific endpoint is not individually documented in the OpenAPI spec, the broader API covers liquidity pool analysis, swap routing, yield optimization, technical analysis, whale tracking, and more.\n\nThe Silverback API is designed for autonomous agents and applications in the DeFi ecosystem. Endpoints follow a consistent pattern: an initial request returns a 402 Payment Required challenge with payment options, the caller signs a USDC authorization via x402, and the paid request returns JSON data. The `/api/v1/top-pools` endpoint likely returns ranked liquidity pool data, complementing the documented `/api/v1/pool-analysis` endpoint which provides deep pool analysis with TVL, APR, and health scoring at $0.01 per call.\n\nNote: During probing, this specific endpoint returned 404 on both GET and POST methods, meaning it may have been renamed, removed, or requires a different request format than was tested. The root landing page at the origin is live (HTTP 200), and the broader Silverback API infrastructure appears operational. Pricing for analysis-tier endpoints in this API is $0.01 per call.","tags":[],"capabilities":["defi-pool-ranking","liquidity-analysis","x402-micropayments","usdc-payments","base-chain","solana-chain","skale-chain","pay-per-use"],"categories":["defi","finance"],"synonyms":["top liquidity pools","best DeFi pools","pool ranking","TVL ranking","liquidity pool leaderboard","DeFi yield pools","pool discovery"],"warnings":["Endpoint returned 404 on both GET and POST — may be removed, renamed, or require different request format","This endpoint is NOT listed in the Silverback OpenAPI spec which documents 11 other endpoints","No request/response schema available for this specific endpoint","External docs URL (https://docs.silverbackdefi.app/) was not crawled; /docs on the x402 subdomain returns 'Cannot GET'"],"endpointUrl":"https://x402.silverbackdefi.app/api/v1/top-pools","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xD34411a70EffbDd000c529bbF572082ffDcF1794","amount":"5000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"8wLKe8H59eni5DmERU27GiRHGnN9fogRoq9yNqyKKNJA"},"payTo":"4HVvnhyXTkMnPbMBo9r3kfvYhzW4JSbLGdXg9SkUcVSe","amount":"5000","scheme":"exact","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","maxTimeoutSeconds":300},{"asset":"0x85889c8c714505E0c94b30fcfcF64fE3Ac8FCb20","extra":{"name":"USD Coin","version":"1"},"payTo":"0xD34411a70EffbDd000c529bbF572082ffDcF1794","amount":"5000","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":"5000","scheme":"keeta-usdc","network":"keeta:main","expiresAt":1771370261239,"paymentId":"28d07df4-1869-4f2e-8514-3cea35d370ab","amountHuman":"0.005000","description":"Top yielding pools on Base DEXes","tokenAddress":"keeta_amnkge74xitii5dsobstldatv3irmyimujfjotftx7plaaaseam4bntb7wnna","maxTimeoutSeconds":300,"requiresPermission":true}]},"qualityScore":"0.300","qualityRationale":"This specific endpoint (/api/v1/top-pools) returned 404 on both GET and POST probes, and it is not listed in the OpenAPI spec.
