It is part of a broader suite of APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments required.\n\nThe specific endpoint `/api/v1/market/quote/MMM` is live and responds with a standard x402 payment challenge. Payment is settled in USDC (USD Coin) on the Base network using the \"exact\" scheme. The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals). The payment is directed to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a timeout of 300 seconds.\n\nDocumentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI schema, no example request/response payloads, and no description of what fields the quote response contains. The endpoint path suggests it returns a market quote for the stock or asset with ticker \"MMM\" (3M Company on NYSE, or possibly another asset), but the exact response schema is unknown.","tags":[],"capabilities":["market-quote","x402-payment","usdc-settlement","base-network","pay-per-call","no-api-key"],"categories":["finance","data"],"synonyms":["market data","stock quote","MMM ticker","3M quote","price quote","asset quote","financial data API","x402 finance"],"warnings":["No API documentation available — /docs, /api, /pricing, and /README pages are all empty","No OpenAPI or output schema provided; response format for the quote is unknown","The ticker 'MMM' is not explicitly defined — it could refer to 3M Company or another asset","This endpoint path (/api/v1/market/quote/MMM) does not appear in the site's listed API catalog, which may indicate it is undocumented or experimental"],"endpointUrl":"https://lowpaymentfee.com/api/v1/market/quote/MMM","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/market/quote/MMM","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 challenge with clear pricing ($0.02 USDC on Base).
