It accepts a POST request with a JSON body containing a `query` parameter and returns a JSON response. The endpoint is operated by Erudite Intelligence LLC and is part of the EruditePay x402 Bridge infrastructure, which supports 20+ blockchains for payment verification and settlement.\n\nPayment is required per-call via the x402 protocol (version 2). The endpoint accepts two payment methods: USDC on Base (eip155:8453) at 10,000 base units ($0.01) per request, or USDT on Tron (tron:728126428) at 10,000 base units ($0.01) per request. Payments are facilitated through Coinbase CDP for the Base chain option. The provider is FinCEN MSB registered (BSA ID 31000324258137) and operates non-custodially.\n\nDocumentation is sparse for this specific endpoint. The description in the x402 challenge is simply \"Crypto data intelligence,\" and the input/output schemas are generic (a `query` string in, a `{success, data}` object out). The exact nature of the Kaspa payment support data returned is not documented in the crawled material. The endpoint is live and returning a proper 402 challenge, but the lack of detailed documentation about what queries are supported or what data is returned limits confidence in its utility.","tags":[],"capabilities":["x402-payment-gated","kaspa-payment-data","crypto-data-intelligence","usdc-base-payment","usdt-tron-payment","json-api","post-endpoint"],"categories":["crypto","search"],"synonyms":["kaspa payment check","kaspa supported payments","crypto payment support","kaspa blockchain data","eruditepay kaspa","x402 crypto intelligence","kaspa payment methods"],"warnings":["Endpoint description is generic ('Crypto data intelligence') with no specifics about Kaspa payment support data","Input/output schemas appear to be placeholders — the example output is just {success: true, data: {}}","No detailed API documentation was found at the crawled URLs; docs.eruditepay.com was not reachable in the crawl","The exact queries supported and data format returned are undocumented"],"endpointUrl":"https://bridge.eruditepay.com/v1/kaspa/payment/supported","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x6961b88476a9b89C4ed97A4aF4D190754d5e70A1","amount":"30000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is live and returns a valid x402 v2 challenge with clear pricing.
