Historical stock price data for SLB (Schlumberger) via x402 micropayment on Base.
What it does
This endpoint provides historical stock price data for the ticker SLB (Schlumberger) through the lowpaymentfee.com platform. 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.
The 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.
Documentation 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.

Quality
The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages render only a wallet-connect prompt. The exact request parameters and response format are entirely unknown, making this effectively a stub listing.
