It is part of a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/accounts/114/statements` accepts POST requests and returns JSON. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 exact scheme with no API keys or rate limits required — callers simply attach an X-PAYMENT header with a valid payment proof.\n\nDocumentation on the platform is extremely sparse. The docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema documentation, and no usage examples available. The endpoint is confirmed live (returns 402 with a well-formed x402 challenge), but the actual data returned after payment and the expected POST body structure are unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","account-statements","json-response","pay-per-request","no-api-key"],"categories":["finance","data"],"synonyms":["account statements API","financial statements endpoint","x402 API","USDC micropayment API","Base network API","pay-per-call API","lowpaymentfee"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'","No OpenAPI or schema definition for request body or response","The specific resource '/api/v1/accounts/114/statements' is unexplained — unclear what account 114 refers to or what statements contain","No request body schema documented; POST body structure is unknown","Platform appears to list many endpoints but provides no technical detail for any of them"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/114/statements","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/accounts/114/statements","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.250","qualityRationale":"The endpoint is live and returns a valid x402 challenge, but there is no documentation, no OpenAPI spec, no request/response examples, and no explanation of what 'accounts/114/statements' actually returns.
