It checks for honeypot behavior, analyzes buy/sell taxes, evaluates ownership and renouncement risks, and returns a risk score with detailed warnings. The endpoint defaults to Base (chain ID 8453) but accepts other EVM chain IDs.\n\nThis is one of 11 pay-per-use DeFi intelligence endpoints in the Silverback x402 API suite. Payment is $0.02 per call, settled in USDC on Base, Solana, or SKALE via the x402 micropayment protocol. Callers first receive a 402 Payment Required response with payment instructions, sign a USDC authorization, and resend with the payment proof header to receive the JSON result.\n\nThe API accepts POST requests with a JSON body containing the token contract address and an optional chain ID. All responses include a `success` boolean field. The broader Silverback platform also offers swap execution, technical analysis, DeFi yield intelligence, arbitrage scanning, whale tracking, wallet portfolio lookup, pool analysis, swap quotes (Base and Solana via Jupiter), and holder analytics — each priced between $0.01 and $0.05 per call.","tags":[],"capabilities":["token-security-audit","honeypot-detection","tax-analysis","ownership-risk-scoring","evm-chain-support","x402-micropayment","pay-per-use","json-api"],"categories":["defi","security","blockchain"],"synonyms":["token audit","smart contract audit","honeypot checker","rug pull detector","token safety check","contract security scan","token risk score","ERC-20 audit"],"warnings":["External docs URL (https://docs.silverbackdefi.app/) was not crawled; the /docs path on the server returns 404.","The 402 challenge object captured in the probe was empty — payment parameters (asset, network, exact amount) could not be independently verified.","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/token-audit","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0xD34411a70EffbDd000c529bbF572082ffDcF1794","amount":"20000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","extra":{"feePayer":"8wLKe8H59eni5DmERU27GiRHGnN9fogRoq9yNqyKKNJA"},"payTo":"4HVvnhyXTkMnPbMBo9r3kfvYhzW4JSbLGdXg9SkUcVSe","amount":"20000","scheme":"exact","network":"solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp","maxTimeoutSeconds":300},{"asset":"0x85889c8c714505E0c94b30fcfcF64fE3Ac8FCb20","extra":{"name":"USD Coin","version":"1"},"payTo":"0xD34411a70EffbDd000c529bbF572082ffDcF1794","amount":"20000","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":"20000","scheme":"keeta-usdc","network":"keeta:main","expiresAt":1771370265629,"paymentId":"499d01f1-fe10-4487-9dd9-8257c6fcca1a","amountHuman":"0.020000","description":"Comprehensive token security audit including honeypot detection, tax analysis, and ownership checks","tokenAddress":"keeta_amnkge74xitii5dsobstldatv3irmyimujfjotftx7plaaaseam4bntb7wnna","maxTimeoutSeconds":300,"requiresPermission":true}]},"qualityScore":"0.720","qualityRationale":"Full OpenAPI schema with clear endpoint description, pricing, and request parameters.
