It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, infrastructure utilities, and more — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/accounts/89/statements` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers receive a 402 challenge containing the payment parameters (asset, amount, payTo address) and must attach a valid X-PAYMENT header to authorize the USDC transfer. The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02. No API keys, rate limits, or upfront commitments are required — access is instant once payment is provided.\n\nDocumentation on the site is extremely sparse. The docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no usage examples available from the crawled material. The endpoint appears live (returning a well-formed 402 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","pay-per-request","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["account statements API","financial statements endpoint","x402 API","USDC micropayment API","pay-per-call statements","lowpaymentfee API","Base network API"],"warnings":["No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content","No request body schema or response schema documented; the POST body structure is unknown","The specific resource '/api/v1/accounts/89/statements' references a hardcoded account ID (89) with no explanation of what data it returns","No OpenAPI or ai-plugin manifest found"],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/89/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/89/statements","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 402 challenge, confirming it is operational.
