It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, covering finance, analytics, AI/ML, crypto, and utility services. Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required.\n\nThe endpoint accepts HTTP POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers include an X-PAYMENT header with a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals). The payment is sent to the provider's address on Base (0x1A2B…85F3) using the canonical USDC contract (0x8335…2913). The x402 challenge confirms the endpoint is live and discoverable.\n\nDocumentation beyond the landing page is sparse — the /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint is confirmed live (402 challenge captured), but the actual data source, update frequency, and response format are unknown. Use with the understanding that you are relying on an undocumented API.","tags":[],"capabilities":["stock-price","real-time-data","x402-payment","usdc-micropayment","base-network","per-request-billing","no-api-key"],"categories":["finance","data"],"synonyms":["LRCX stock price","Lam Research price API","stock quote API","equity price endpoint","micropayment stock data","x402 stock API","pay-per-call stock price"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","All doc/pricing/README pages return only a 'Connect wallet' prompt with no technical content","Data source and update frequency for LRCX stock price are undisclosed","No example request or response payloads available anywhere in crawled material"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/LRCX/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/LRCX/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
