Real-time stock price data for SYK (Stryker Corp) via x402 micropayment on Base.
What it does
This endpoint provides real-time stock price data for the ticker SYK (Stryker Corporation) through the x402 payment protocol. It is hosted on lowpaymentfee.com, a platform offering a variety of pay-per-request APIs spanning data analytics, AI/ML, finance, crypto, and utility services. All endpoints on the platform use the same pricing model: $0.02 per request, settled in USDC on the Base network with no API keys, no rate limits, and no commitments required.
The specific endpoint at `/api/v1/stocks/SYK/price` 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. The x402 challenge was confirmed live, returning a proper 402 response with version 1 of the protocol.
Documentation on the site is extremely thin — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no example request/response payloads, and no description of the response format beyond the stated mimeType of `application/json`. The endpoint URL pattern suggests it may support other stock tickers by substituting the symbol in the path, but this is not confirmed.

Quality
The x402 challenge is live and well-formed, confirming the endpoint exists and accepts payments. However, there is no OpenAPI schema, no documented request/response format, no example payloads, and the site's docs pages are empty beyond a wallet-connect prompt. The listing is functional but information-sparse.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown beyond application/json
- —Docs, API, pricing, and README pages on the site all render only 'Connect wallet' with no usable content
- —It is unclear whether the endpoint returns delayed or real-time quotes, or what fields are included in the response
- —The endpoint path suggests other tickers may be supported (e.g., /stocks/{TICKER}/price) but this is unconfirmed
