It is part of a broader platform offering data, analytics, AI, finance, and utility APIs — all priced at $0.02 per request and payable with USDC on the Base network using the x402 protocol. No API keys, accounts, or rate limits are required; payment is handled inline via the X-PAYMENT header.\n\nThe x402 challenge confirms the endpoint is live, accepting payments to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a max amount of 20,000 base units of USDC (USD Coin, 6 decimals), which equals $0.02 per call. The response MIME type is application/json. The specific schema of the returned stock data is not documented in the crawled material, so the exact fields (price, volume, change, etc.) are unknown.\n\nThe platform's landing page lists many sibling endpoints across finance, AI/ML, data analytics, and infrastructure categories, all at the same $0.02 price point. Documentation pages (/docs, /pricing, /README) returned only a \"Connect wallet\" prompt with no additional technical detail, so the request body format and response schema for this stock endpoint remain undocumented.","tags":[],"capabilities":["stock-quote","per-call-payment","x402-protocol","usdc-settlement","base-network","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["stock price API","SLB stock data","Schlumberger quote","equity data endpoint","pay-per-call stock API","x402 stock quote","USDC stock API"],"warnings":["No documentation available — /docs, /pricing, and /README pages return only a wallet-connect prompt with no technical content.","Request body schema is unknown; it is unclear what (if any) parameters the POST body accepts.","Response schema is unknown; the fields returned for stock data are not documented anywhere in the crawl.","Data source and freshness (real-time vs. delayed) for stock quotes is unspecified.","The platform lists many diverse endpoints (AI, analytics, finance, utilities) all at $0.02 — quality and depth of each is unverifiable."],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/SLB","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/SLB","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 with clear pricing ($0.02 USDC on Base).
