It is part of a broader suite of pay-per-call APIs offered by the provider, spanning data analytics, AI/ML inference, finance/Web3, and utility services. All endpoints are gated behind the x402 payment protocol, settling in USDC on the Base network.\n\nThe specific endpoint `/api/v1/wallet/BLUR/balance` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base), which equals $0.02 per request (USDC uses 6 decimals). The provider's landing page confirms a flat $0.02/request pricing model across all endpoints, with no API keys, no rate limits, and no minimum commitments required.\n\nDocumentation is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is live (returns a proper 402 x402 challenge), but the actual response format and required request body fields are unknown. The wallet balance endpoint likely returns a JSON object with balance information for the BLUR token, but this is inferred from the endpoint path rather than documented.","tags":[],"capabilities":["wallet-balance-query","blur-token","x402-payment","usdc-settlement","base-network","pay-per-call","no-api-key"],"categories":["crypto","finance"],"synonyms":["BLUR balance","token balance API","wallet balance check","crypto balance lookup","BLUR wallet","Web3 balance API","ERC-20 balance"],"warnings":["No documentation available — /docs, /api, /pricing, and /README pages all show only 'Connect wallet' with no technical content","No OpenAPI or schema definition found; request body and response format are unknown","Example request JSON is speculative — actual required fields are undocumented","The broader provider site lists many endpoint categories but this specific wallet balance endpoint is not listed on the landing page"],"endpointUrl":"https://lowpaymentfee.com/api/v1/wallet/BLUR/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/BLUR/balance","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base).
