It 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 endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.\n\nThe specific endpoint `/api/v1/wallet/RSR/balance` accepts POST requests and costs $0.02 per call (20,000 base units of USDC with 6 decimals). No API keys or accounts are required — payment is handled inline via the x402 `X-PAYMENT` header. The platform advertises no rate limits and instant access.\n\nDocumentation on the site is extremely thin. The docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what parameters the endpoint expects (e.g., a wallet address) or what fields the response contains. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes integration speculative.","tags":[],"capabilities":["wallet-balance-query","rsr-token","x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key"],"categories":["crypto","finance"],"synonyms":["RSR balance","Reserve Rights balance","token balance API","crypto wallet balance","RSR wallet lookup","x402 crypto API","Base network API"],"warnings":["No documentation available — docs, pricing, API, and README pages all render only 'Connect wallet'","No OpenAPI or schema definition; request parameters and response format are unknown","Example request body (address field) is inferred and not confirmed by any source material","The broader platform lists many endpoints but none have documented schemas"],"endpointUrl":"https://lowpaymentfee.com/api/v1/wallet/RSR/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/RSR/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.
