It is accessed via HTTP POST with a JSON body specifying the chain to monitor. The endpoint is live and returns an x402 v2 payment challenge, accepting USDC on Base (eip155:8453) or USDT on Tron (tron:728126428) at a cost of $0.01 per call (10,000 base units with 6 decimals).\n\nThe response schema indicates a JSON object with a `success` boolean and a `data` object, though the exact structure of the returned contract data is not documented beyond the example stub `{\"success\": true, \"data\": {}}`. The endpoint is described as \"Crypto data intelligence\" in the x402 challenge. The provider, EruditePay, operates an x402 payment facilitator bridge supporting 20 blockchains and is registered as a FinCEN MSB (BSA ID 31000324258137).\n\nDocumentation is sparse — the provider's /docs, /api, and /README paths all return 404-style errors. The input schema accepts a `chain` string parameter describing the blockchain network to monitor, with \"base\" shown as the example value. No detailed field-level documentation exists for the response payload, so consumers should expect to explore the response structure empirically.","tags":[],"capabilities":["new-contract-monitoring","blockchain-data","base-chain","smart-contract-detection","crypto-intelligence","x402-payment","multi-chain-payment"],"categories":["crypto","blockchain","monitoring"],"synonyms":["new smart contracts","contract deployment monitor","base chain contracts","blockchain contract tracker","deployed contracts API","on-chain contract discovery","new token contracts"],"warnings":["Response data structure is undocumented — the example shows an empty object","Provider documentation pages (/docs, /api, /README) all return endpoint_not_found errors","The exact fields returned in the 'data' object are unknown; consumers must discover them empirically"],"endpointUrl":"https://bridge.eruditepay.com/v1/base/monitor/new-contracts","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x24c5da6267AEbEBfCBf7B325753C5B2538A5B09B","amount":"5000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300},{"asset":"TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t","extra":{"name":"TronTransferAuthorization","version":"1","wrapper":"THGkLBrLY1G5VovZjjK1jP9upyxRdMNL3b"},"payTo":"TSevuRZFjpckeMSSDhQFoiAkPCkckuE5TP","amount":"5000","scheme":"exact","network":"tron:728126428","maxTimeoutSeconds":300}]},"qualityScore":"0.450","qualityRationale":"The endpoint is live (402 challenge captured) with a clear input schema and pricing, but the response payload is entirely undocumented beyond a stub example with an empty data object.
