It is part of the EruditePay Bridge infrastructure, which describes itself as a \"Crypto data intelligence\" provider. The endpoint is live and responds with an x402 v2 payment challenge, accepting payment in USDC on Base (EIP-155:8453) or USDT on Tron before returning results.\n\nThe cost per call is $0.01 (10,000 base units of a 6-decimal stablecoin). Payment can be made via USDC on Base to address 0x6961b88476a9b89C4ed97A4aF4D190754d5e70A1, or via USDT on Tron to TTikV9JD3xTfk5TDv8HMEvpWmNQS8Fm6Pw. The facilitator for Base payments is Coinbase CDP's x402 endpoint. The request body is a JSON object with a single field, `address`, representing the wallet or contract address to check. The response is a JSON object with a `success` boolean and a `data` object (contents of `data` are not documented beyond the empty example).\n\nDocumentation is sparse — the provider's /docs path returns a 404, and no OpenAPI spec is available. The exact sanctions lists checked, the structure of a positive match in the response `data` field, and rate limits are all undocumented. The provider is a FinCEN-registered MSB (BSA ID 31000324258137) and operates non-custodially.","tags":[],"capabilities":["sanctions-screening","wallet-address-lookup","x402-payment","usdc-base","usdt-tron","compliance-check","crypto-intelligence"],"categories":["compliance","crypto"],"synonyms":["OFAC check","sanctions screening","wallet sanctions","address screening","AML check","crypto compliance","blockchain sanctions","address risk check"],"warnings":["No documentation available — /docs returns 404 and no OpenAPI spec exists","Response data structure is undocumented; the example shows an empty object","Sanctions/compliance is a regulated category — verify the provider's methodology and list coverage independently","Unknown which sanctions lists (OFAC SDN, EU, UN, etc.) are checked","No rate limit or usage policy documented"],"endpointUrl":"https://bridge.eruditepay.com/v1/base/address/sanctions-check","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x6961b88476a9b89C4ed97A4aF4D190754d5e70A1","amount":"8000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300}]},"qualityScore":"0.450","qualityRationale":"The endpoint is live and returns a well-formed x402 v2 challenge with clear pricing and a basic schema.
