Stock market quote for BKNG (Booking Holdings) via x402 micropayment on Base.
What it does
This endpoint at lowpaymentfee.com returns a market quote for the ticker symbol BKNG (Booking Holdings) in exchange for a per-request x402 micropayment of $0.02 settled in USDC on the Base network. The endpoint is live and returns a standard x402 challenge (HTTP 402) requiring an X-PAYMENT header with a payment proof before serving data.
The provider operates a broader platform offering dozens of pay-per-call API endpoints across categories including data analytics, AI/ML inference, finance/crypto market data, and utility services — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access. This specific endpoint sits under the market quote path (`/api/v1/market/quote/{ticker}`) and uses HTTP POST.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no example request/response payloads, and no description of the response format beyond the MIME type `application/json`. The actual data source backing the market quotes is not disclosed.
