Stock market quote for KO (Coca-Cola) via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns a market quote for the ticker symbol KO (Coca-Cola) 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 priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/market/quote/KO` accepts POST requests and is gated by an x402 payment challenge. The maximum amount required is 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the `exact` scheme to the specified payTo address, with a 300-second timeout. No API keys or rate limits are advertised; access is instant once payment is included in the X-PAYMENT header.
Documentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint is confirmed live (returns 402 with a valid x402 challenge), but the actual data source, response format, and field definitions are unknown.
