It is part of a broader suite of APIs hosted at lowpaymentfee.com covering data analytics, AI/ML inference, finance, crypto, and utility services — all sharing the same pay-per-use model.\n\nThe endpoint accepts x402 payments on the Base network using USDC (contract 0x8335…2913). Each request costs a maximum of $0.02 (20,000 base units at 6 decimals). There are no API keys, no rate limits, and no subscriptions — you simply attach an X-PAYMENT header with a valid x402 payment proof and receive a JSON response. The payment timeout is 300 seconds.\n\nDocumentation beyond the landing page is extremely sparse: 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 example request/response, and no description of the response payload structure. The endpoint is confirmed live (returns a proper 402 challenge), but the actual data source for stock prices and the response format are unknown.","tags":[],"capabilities":["stock-price-lookup","x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key"],"categories":["finance","data"],"synonyms":["stock price API","MO stock price","Altria stock quote","equity price lookup","real-time stock data","x402 stock API","pay-per-call stock price"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","All doc pages (/docs, /pricing, /api, /README) render only 'Connect wallet' with no content","The data source for stock prices is not disclosed; accuracy and freshness are unverifiable","The endpoint path is ticker-specific (/stocks/MO/price); it is unclear whether other tickers are supported"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/MO/price","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/MO/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base).
