Historical stock data for ABT (Abbott Laboratories) via x402 micropayment on Base.
What it does
This endpoint provides historical stock price data for the ticker ABT (Abbott Laboratories) through the x402 payment protocol. It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance, crypto, and utility endpoints—all gated behind per-request x402 micropayments settled in USDC on the Base network.
The specific endpoint `/api/v1/stocks/ABT/history` accepts POST requests and returns JSON. Each call costs a maximum of $0.02 (20,000 base units of USDC with 6 decimals). The platform advertises no API keys, no rate limits, and instant access—you pay per request using an X-PAYMENT header containing a signed x402 payment envelope. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` on Base.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no description of what fields the historical stock data includes (e.g., OHLCV, date ranges, granularity). The endpoint is confirmed live via a valid 402 challenge response, but the actual data format and query parameters remain unknown.
