It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe broader lowpaymentfee.com platform advertises a suite of pay-per-call APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/crypto market data, and infrastructure utilities, all priced at $0.02 per request. However, this specific listing covers only the `/api/v1/accounts/152/statements` endpoint. The site's documentation, pricing, and README pages are stub pages behind a \"Connect wallet\" gate, so detailed schema information, request/response field definitions, and usage examples are not available from the crawl.\n\nThe endpoint is confirmed live: it returns a well-formed x402 version 1 challenge with a 402 status code. The payment scheme is \"exact\" with a 300-second timeout. Because no OpenAPI spec, request body schema, or sample responses were found, the actual data returned by this endpoint remains unclear beyond the generic \"Premium API Access\" description and the JSON MIME type.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","account-statements","pay-per-request","json-response","no-api-key"],"categories":["finance","data"],"synonyms":["account statements API","financial statements endpoint","x402 pay-per-call","USDC micropayment API","lowpaymentfee","Base network API","402 payment required"],"warnings":["No OpenAPI or schema documentation available — request body and response structure are unknown.","All documentation pages (/docs, /pricing, /README, /api) return only a 'Connect wallet' stub with no usable content.","The endpoint is scoped to a single hardcoded account ID (152); unclear if other account IDs are supported or how they are provisioned.","The 'Premium API Access' description is generic and does not clarify what data is actually returned."],"endpointUrl":"https://lowpaymentfee.com/api/v1/accounts/152/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/152/statements","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live via a valid x402 402 challenge, but there is no OpenAPI spec, no request/response schema, no documentation beyond stub pages, and the endpoint's purpose ('Premium API Access' for account 152 statements) is vague.
