The endpoint accepts POST requests and returns JSON. Payment is settled in USDC on the Base network at $0.02 per request (maxAmountRequired of 20,000 base units with USDC's 6 decimals = $0.02). No API keys, rate limits, or subscriptions are required — each call is individually paid via the x402 protocol.\n\nThe provider (lowpaymentfee.com) hosts a broader suite of APIs spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all priced uniformly at $0.02 per request. The specific endpoint probed here (/api/v1/stocks/MO) is a stock-specific route not explicitly listed on the landing page's catalog, but it follows the same URL pattern and pricing scheme as the other finance endpoints. The landing page confirms the pricing model: pay-per-use with no minimums, no commitments, and instant access.\n\nDocumentation is extremely sparse. The /docs, /api, /pricing, and /README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no response examples, and no field-level documentation for what the stock data response contains. The endpoint is confirmed live (402 challenge captured), but the actual response payload structure is unknown.","tags":[],"capabilities":["stock-quote","per-call-payment","x402-protocol","usdc-base","no-api-key","pay-per-use","json-response"],"categories":["finance","data"],"synonyms":["stock price API","equity data","MO stock","Altria stock quote","stock market data","micropayment API","x402 stock data","pay-per-call finance"],"warnings":["No documentation available — /docs, /pricing, /api, and /README pages all return only a 'Connect wallet' prompt with no content.","The /api/v1/stocks/MO endpoint is not listed in the provider's own API catalog on the landing page, raising questions about its support status.","No response schema or example response is available; the structure and fields of the stock data are unknown.","No OpenAPI or machine-readable schema is published."],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/MO","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","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).
