It is operated by Erudite Intelligence LLC and described in the x402 challenge as \"Crypto data intelligence.\" The endpoint accepts a POST request with a JSON body containing a token address (or pair identifier) and returns quote data in JSON format.\n\nPayment is required via the x402 protocol (version 2). The endpoint accepts two payment options: USDC on Base (network eip155:8453) at 10,000 base units ($0.01 per call, since USDC uses 6 decimals), or USDT on Tron (network tron:728126428) at 10,000 base units ($0.01 per call). Payment is facilitated through the Coinbase CDP x402 facilitator for the Base option. The provider is FinCEN MSB registered (BSA ID 31000324258137) and the bridge supports 20 blockchains for settlement.\n\nDocumentation is sparse — the /docs path returns a 404, and the Bazaar schema embedded in the x402 challenge provides only a minimal example with a token address field and a generic success/data response shape. The exact structure of the returned quote data (e.g., price, liquidity, slippage) is not documented in the available materials. The endpoint is confirmed live, returning a proper 402 challenge on POST requests.","tags":[],"capabilities":["dex-quote","base-chain","token-pricing","x402-payment","usdc-payment","usdt-tron-payment","crypto-data-intelligence"],"categories":["crypto","defi","data"],"synonyms":["DEX price quote","token swap quote","Base DEX pricing","decentralized exchange quote","crypto token quote","on-chain price data","EruditePay DEX"],"warnings":["No dedicated documentation available — /docs returns 404","Response schema example is a stub with empty data object; actual response fields are unknown","Input schema only documents a 'token' field; additional parameters (e.g., amount, slippage) may exist but are undocumented","No OpenAPI specification available"],"endpointUrl":"https://bridge.eruditepay.com/v1/base/dex/quote","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x24c5da6267AEbEBfCBf7B325753C5B2538A5B09B","amount":"3000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t","extra":{"name":"TronTransferAuthorization","version":"1","wrapper":"THGkLBrLY1G5VovZjjK1jP9upyxRdMNL3b"},"payTo":"TSevuRZFjpckeMSSDhQFoiAkPCkckuE5TP","amount":"3000","scheme":"exact","network":"tron:728126428","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is confirmed live with a valid x402 v2 challenge and clear pricing ($0.01/call).
