It is part of a broader suite of pay-per-request APIs offered by the same provider, spanning data analytics, AI/ML inference, finance, crypto, and utility services. The specific endpoint `/api/v1/stocks/TSLA` accepts POST requests and returns JSON.\n\nPricing is $0.02 per request, paid in USDC on the Base network. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, which has 6 decimals), equaling $0.02. No API keys are required; payment is handled inline via the X-PAYMENT header per the x402 protocol. The provider advertises no rate limits and instant access.\n\nDocumentation is extremely sparse. The docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the stock data response contains. The endpoint is confirmed live (returns 402 with a valid x402 challenge), but the actual data quality and response format are unknown.","tags":[],"capabilities":["stock-data","pay-per-request","x402-payment","usdc-settlement","base-network","json-response"],"categories":["finance","data"],"synonyms":["TSLA stock API","Tesla stock price","stock quote API","x402 stock data","pay-per-call finance API","micropayment stock API","Base USDC API"],"warnings":["No API documentation available — docs, pricing, and README pages all show only 'Connect wallet'","No request body schema or response schema documented anywhere","Unknown what stock data fields are returned (price, volume, OHLC, etc.)","No OpenAPI or machine-readable spec provided","The /api/v1/stocks/TSLA path is not listed on the provider's homepage; only generic categories are shown"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/TSLA","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/stocks/TSLA","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).
