It is part of a broader suite of pay-per-call APIs offered by the same provider, spanning data analytics, AI/ML inference, finance/Web3, and utility services. All endpoints use the x402 payment protocol, settling in USDC on the Base network.\n\nThe specific endpoint `/api/v1/wallet/LUNC/balance` accepts POST requests and returns JSON. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). No API keys are required; payment is handled entirely through the X-PAYMENT header. The provider advertises no rate limits and instant access.\n\nDocumentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no usage examples available from the crawl. The endpoint is confirmed live (returns a proper 402 challenge), but the actual response format and accepted request parameters are unknown.","tags":[],"capabilities":["crypto-wallet-balance","lunc-balance","x402-payment","usdc-settlement","base-network","pay-per-call"],"categories":["crypto","finance"],"synonyms":["LUNC balance API","Terra Classic wallet balance","crypto balance lookup","LUNC wallet query","Terra Luna Classic balance"],"warnings":["No OpenAPI or schema documentation available — request/response formats are unknown","All documentation pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content","Example request JSON is inferred/guessed; actual required fields are unconfirmed","Provider offers many endpoints but none have published technical docs"],"endpointUrl":"https://lowpaymentfee.com/api/v1/wallet/LUNC/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/LUNC/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).
