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. All endpoints use the x402 protocol on the Base network, accepting USDC payments with no API keys, no rate limits, and no subscriptions required.\n\nThe endpoint is live and responds with a standard x402 payment challenge. It accepts POST requests and charges a maximum of 20,000 base units of USDC (0.02 USD) per call, settled on the Base L2 network to the specified payTo address. The asset used is USDC at contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913. The response MIME type is application/json.\n\nDocumentation on the site is extremely sparse — the docs, pricing, API, and README pages all render only a \"Connect wallet\" prompt with no additional content. There is no OpenAPI schema, no example request/response payloads, and no detailed documentation for the stock price endpoint specifically. The exact shape of the returned JSON (e.g., whether it includes timestamp, open/close, volume) is unknown and must be discovered by making a paid call.","tags":[],"capabilities":["stock-price-lookup","real-time-market-data","x402-micropayment","usdc-payment","base-network","pay-per-request","no-api-key"],"categories":["finance","data"],"synonyms":["stock price API","XOM price","ExxonMobil stock","equity price feed","market data API","x402 stock data","micropayment stock API"],"warnings":["No documentation available beyond the landing page — docs, pricing, API, and README pages all show only 'Connect wallet'","No OpenAPI or JSON schema describing the response format for the stock price endpoint","No example responses available; the exact fields returned are unknown","The endpoint URL is hardcoded to ticker XOM — it is unclear whether other tickers are supported at similar paths"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/XOM/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/XOM/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base).
