Each call costs $0.02 (20,000 base units of USDC on the Base network, where USDC has 6 decimals). No API keys or rate limits are required — callers simply attach an x402 payment header to a POST request and receive a JSON response.\n\nThe endpoint is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced at $0.02 per request. The platform settles payments on the Base L2 network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge was successfully captured, confirming the endpoint is live.\n\nDocumentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of what parameters the endpoint accepts (e.g., whether a DOGE address is passed in the POST body or as a path parameter). The endpoint path suggests it returns a balance for a DOGE wallet, but the exact input format and response structure are unknown.","tags":[],"capabilities":["doge-balance","crypto-wallet-query","x402-payment","base-network-usdc","pay-per-request"],"categories":["crypto","finance"],"synonyms":["dogecoin balance","DOGE wallet balance","crypto balance lookup","dogecoin address balance","wallet balance API","DOGE balance check"],"warnings":["No API documentation available — docs, pricing, API, and README pages all return only a wallet-connect prompt with no technical content.","Request and response schemas are entirely unknown; the example request is speculative.","No OpenAPI or machine-readable schema was found.","The broader platform lists many endpoints across diverse categories (AI, analytics, finance, utilities) all at the same price, which may indicate a generic or placeholder service."],"endpointUrl":"https://lowpaymentfee.com/api/v1/wallet/DOGE/balance","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/wallet/DOGE/balance","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02/request in USDC on Base).
