The API covers swap routing (Base and Solana via Jupiter), technical analysis, DeFi yield opportunities, cross-DEX arbitrage scanning, token security audits, whale transaction tracking, wallet portfolio lookups, liquidity pool analysis, swap quotes, holder analytics, and DEX metrics. Payments are made in USDC on Base, Solana, or SKALE (zero gas), with an optional 15% discount when paying with the $BACK token via Permit2 on Base.\n\nPricing is tiered by endpoint complexity: execution endpoints (swap) cost $0.05 per call, heavy analysis endpoints (technical-analysis, defi-yield, arbitrage-scanner) cost $0.03, intelligence endpoints (token-audit, whale-moves, wallet-portfolio) cost $0.02, and lighter analysis endpoints (pool-analysis, swap-quote, jupiter-quote, holder-analytics) cost $0.01. All responses return JSON with a `success` boolean field. Token identifiers use CoinGecko IDs for market data or 0x contract addresses for on-chain queries; chain defaults to Base (chain ID 8453) unless specified.\n\nNote: The specific `/api/v1/dex-metrics` endpoint listed here returned 404 during probing on both GET and POST, though the OpenAPI spec hosted at the origin describes 11 endpoints and the root landing page is live. The canonical server URL in the OpenAPI spec is `https://x402.silverbackdefi.app`, which may differ from the probed Render URL. Agents should verify the endpoint is reachable at the canonical host before relying on it.","tags":[],"capabilities":["dex-metrics","token-swap","technical-analysis","defi-yield","arbitrage-scanning","token-audit","whale-tracking","wallet-portfolio","pool-analysis","swap-quote","jupiter-quote-solana","holder-analytics","x402-micropayments","permit2-signing"],"categories":["defi","crypto","finance"],"synonyms":["DEX metrics API","DeFi analytics","on-chain intelligence","swap routing API","liquidity pool analysis","whale tracker","token security audit","yield farming API","arbitrage scanner","crypto portfolio API"],"warnings":["The /api/v1/dex-metrics endpoint returned 404 on both POST and GET during probing — it may not be live at the probed Render URL.","The OpenAPI spec lists the canonical server as https://x402.silverbackdefi.app, not the probed https://silverback-x402.onrender.com — the endpoint may only work at the canonical host.","The /api/v1/dex-metrics path is NOT listed in the OpenAPI spec's paths object; its request/response schema is unknown.","The /docs URL returns 'Cannot GET /docs' — external documentation is not accessible at the probed host."],"endpointUrl":"https://silverback-x402.onrender.com/api/v1/dex-metrics","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xD34411a70EffbDd000c529bbF572082ffDcF1794","amount":"2000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"8wLKe8H59eni5DmERU27GiRHGnN9fogRoq9yNqyKKNJA"},"payTo":"4HVvnhyXTkMnPbMBo9r3kfvYhzW4JSbLGdXg9SkUcVSe","amount":"2000","scheme":"exact","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","maxTimeoutSeconds":300},{"asset":"0x85889c8c714505E0c94b30fcfcF64fE3Ac8FCb20","extra":{"name":"USD Coin","version":"1"},"payTo":"0xD34411a70EffbDd000c529bbF572082ffDcF1794","amount":"2000","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":"2000","scheme":"keeta-usdc","network":"keeta:main","expiresAt":1771370263307,"paymentId":"9497672c-bc4b-483a-8773-7bc8873969fc","amountHuman":"0.002000","description":"Base chain DEX ecosystem overview with volume, TVL, gas stats, and top pairs","tokenAddress":"keeta_amnkge74xitii5dsobstldatv3irmyimujfjotftx7plaaaseam4bntb7wnna","maxTimeoutSeconds":300,"requiresPermission":true}]},"qualityScore":"0.450","qualityRationale":"The OpenAPI spec is comprehensive with 11 well-documented endpoints and clear pricing, but the specific /api/v1/dex-metrics endpoint returned 404 on both GET and POST during probing.
