It computes RSI, MACD, Bollinger Bands, trend detection, and trading recommendations over configurable timeframes (1, 7, 14, or 30 days). The endpoint is part of the Silverback x402 DeFi Intelligence API, which offers 11 pay-per-use endpoints covering swap execution, yield analysis, arbitrage scanning, token audits, whale tracking, and more.\n\nPayment is handled via the x402 micropayment protocol. Each call to the technical-analysis endpoint costs $0.03 in USDC, settled on Base, Solana, or SKALE. The flow is: send a POST request with a JSON body specifying the token and optional timeframe, receive a 402 Payment Required challenge with payment options, sign a USDC authorization, and resend with the payment proof header to receive the JSON response.\n\nThe endpoint accepts POST requests with a JSON body containing a required `token` field (CoinGecko ID such as \"bitcoin\", \"ethereum\", or \"solana\") and an optional `timeframe` field (\"1\", \"7\", \"14\", or \"30\" days). All responses include a `success` boolean field. The API is live and returns a 402 challenge as expected for the x402 protocol. Note that the external docs URL (docs.silverbackdefi.app) was not reachable during crawl, so detailed response schemas are inferred from the OpenAPI spec descriptions only.","tags":[],"capabilities":["technical-analysis","rsi","macd","bollinger-bands","trend-detection","trading-recommendation","x402-micropayment","usdc-payment","multi-chain-settlement","pay-per-use"],"categories":["defi","finance","crypto"],"synonyms":["crypto technical analysis","token TA","RSI MACD API","trading signals API","DeFi market analysis","chart indicators API","cryptocurrency indicators","Silverback TA"],"warnings":["External docs at docs.silverbackdefi.app were not reachable during crawl","The 402 challenge object was empty — payment network details are inferred from OpenAPI guidance only","No example response schema or sample response body is available","The canonical server URL in the OpenAPI spec is https://x402.silverbackdefi.app but the probed endpoint is on silverback-x402.onrender.com — these may diverge"],"endpointUrl":"https://silverback-x402.onrender.com/api/v1/technical-analysis","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xD34411a70EffbDd000c529bbF572082ffDcF1794","amount":"30000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"8wLKe8H59eni5DmERU27GiRHGnN9fogRoq9yNqyKKNJA"},"payTo":"4HVvnhyXTkMnPbMBo9r3kfvYhzW4JSbLGdXg9SkUcVSe","amount":"30000","scheme":"exact","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","maxTimeoutSeconds":300},{"asset":"0x85889c8c714505E0c94b30fcfcF64fE3Ac8FCb20","extra":{"name":"USD Coin","version":"1"},"payTo":"0xD34411a70EffbDd000c529bbF572082ffDcF1794","amount":"30000","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":"30000","scheme":"keeta-usdc","network":"keeta:main","expiresAt":1771370265193,"paymentId":"1cd8d4a0-9b88-46a5-bf49-deca7fc680e5","amountHuman":"0.030000","description":"Technical analysis with RSI, MACD, Bollinger Bands","tokenAddress":"keeta_amnkge74xitii5dsobstldatv3irmyimujfjotftx7plaaaseam4bntb7wnna","maxTimeoutSeconds":300,"requiresPermission":true}]},"qualityScore":"0.650","qualityRationale":"The OpenAPI spec is well-structured with clear parameter schemas, pricing info, and endpoint descriptions.
