It is part of a broader suite of pay-per-request APIs covering finance, AI/ML, data analytics, and infrastructure utilities, all gated behind the x402 payment protocol on the Base network.\n\nThe endpoint accepts POST requests and returns JSON. Each call costs $0.02 in USDC (USD Coin) on Base, settled on-chain with no API keys, no rate limits, and no upfront commitments. The x402 challenge was confirmed live, advertising a maxAmountRequired of 20,000 base units of USDC (6 decimals → $0.02). Payment is sent to the provider's wallet address and the endpoint responds with the requested data.\n\nDocumentation is extremely sparse — the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the history endpoint returns or what query parameters it accepts. The endpoint path suggests it returns historical price data for the SLB stock ticker, but the exact shape of the response (date range, granularity, fields) is unknown.","tags":[],"capabilities":["stock-history","financial-data","x402-payment","usdc-base","pay-per-request","no-api-key"],"categories":["finance","data"],"synonyms":["stock price history","SLB historical data","Schlumberger stock","equity price API","stock market data","x402 stock API","micropayment stock data"],"warnings":["No API documentation available — docs, pricing, and API pages all show only 'Connect wallet'","No OpenAPI or JSON schema for request or response bodies","Exact request parameters (date range, granularity, etc.) are unknown","Response format and fields are undocumented","The provider hosts many diverse endpoints (AI, finance, utilities) all at $0.02 — unclear if all are fully implemented"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/SLB/history","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/history","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).
