It is part of the Silverback x402 DeFi Intelligence API, which offers 11 pay-per-use endpoints covering swap execution, technical analysis, yield intelligence, arbitrage scanning, token audits, whale tracking, wallet portfolios, and more.\n\nThis specific endpoint accepts a POST request with token pair identifiers (symbols like WETH/USDC or 0x contract addresses) or a direct pool address. It costs $0.01 per call, paid in USDC via the x402 micropayment protocol on Base, Solana, or SKALE networks. The $BACK token can also be used for a 15% discount via Permit2 on Base. The endpoint defaults to Base (chain ID 8453) unless otherwise specified.\n\nThe API follows the standard x402 flow: an initial request returns a 402 Payment Required response with payment options; the caller signs a USDC authorization and resends with a payment proof header to receive the JSON result. All responses include a `success` boolean field. Both GET (query params) and POST (JSON body) are generally supported across Silverback endpoints.","tags":[],"capabilities":["liquidity-pool-analysis","tvl-reporting","apr-estimation","health-scoring","x402-micropayments","defi-intelligence","base-chain","solana-chain","skale-chain","usdc-payments"],"categories":["defi","finance","blockchain"],"synonyms":["liquidity pool analyzer","DeFi pool health","pool TVL checker","AMM pool analysis","DEX pool metrics","liquidity depth analysis","pool APR calculator"],"warnings":["External docs at /docs return 'Cannot GET /docs' — documentation link is broken on the Render-hosted instance","The x402 challenge object was captured as empty ({}) — payment details (accepts array, token addresses) were not recorded in the probe","No example response schema is provided; response structure is inferred from the summary only","The endpoint is hosted on Render free/hobby tier (onrender.com) which may have cold-start latency"],"endpointUrl":"https://silverback-x402.onrender.com/api/v1/pool-analysis","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":1771370265753,"paymentId":"c6937da7-4c7a-40e8-87e4-59b4e1a4858c","amountHuman":"0.010000","description":"Analyze Base chain liquidity pools with health scoring","tokenAddress":"keeta_amnkge74xitii5dsobstldatv3irmyimujfjotftx7plaaaseam4bntb7wnna","maxTimeoutSeconds":300,"requiresPermission":true}]},"qualityScore":"0.650","qualityRationale":"Full OpenAPI schema with clear endpoint description, pricing, and request parameters are available.
