Stock market quote for SBUX via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides a real-time stock market quote for SBUX (Starbucks) 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/SBUX` accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers attach an `X-PAYMENT` header with a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals). No API keys, rate limits, or upfront commitments are required — each call is individually paid for on-chain.
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. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint is live (returns a valid 402 challenge), but the exact fields returned in a successful quote response are unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, no example payloads, and all documentation pages beyond the landing page are empty ('Connect wallet' only). The actual content of a successful response is entirely unknown.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All doc/pricing/API/README pages render only 'Connect wallet' with no content
- —The endpoint path suggests a single-ticker quote (SBUX); it is unclear whether other tickers are supported via path parameter substitution
- —No examples of successful responses were found anywhere in the crawl
