Stock market quote for SLB via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns a market quote for the ticker symbol SLB (Schlumberger / SLB Ltd.) via the x402 payment protocol. It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, covering finance, analytics, AI/ML, and utility services. Payment is settled on the Base network using USDC at $0.02 per request with no API keys, rate limits, or subscriptions required.
The x402 challenge confirms the endpoint is live and accepts POST requests. The payment scheme is "exact" with a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02. The asset address (0x8335…) corresponds to USDC on Base. Callers attach an X-PAYMENT header containing the x402 payment proof to receive the JSON response.
The specific endpoint path `/api/v1/market/quote/SLB` suggests it returns a stock or market quote for the SLB ticker. However, no response schema or example response is documented in the crawled material, so the exact fields returned are unknown. The provider's landing page lists this under "Finance & Web3" alongside price feeds, exchange rates, and crypto quotes, but detailed API documentation pages returned only a "Connect wallet" prompt with no further content.
