Stock market quote for ACN (Accenture) via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns a market quote for the ticker symbol ACN (Accenture) through the x402 payment protocol. It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, which spans data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints on the platform share a uniform $0.02-per-request pricing model settled in USDC on the Base network.
The specific endpoint `/api/v1/market/quote/ACN` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment of up to 20,000 base units (i.e., $0.02 given USDC's 6 decimals) to the designated payTo address on Base. No API keys, accounts, or rate limits are advertised — access is gated solely by the micropayment.
Documentation beyond the landing page is extremely sparse. The /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical detail, request/response schemas, or usage examples. The actual response schema for the quote endpoint is not documented, so the exact fields returned (e.g., price, volume, timestamp) must be inferred from the endpoint's name and category.

However, there is no documented request or response schema, no usage examples, and all documentation pages return only a wallet-connect prompt. The actual data returned by the quote endpoint is entirely unknown.
